ATI TEAS 7 MATH LATEST VERSION | REAL EXAM, 31 QUESTIONS & ANSWERS, 100% CORRECT Q & A | ATI TEAS MATH Question 1 CORRECT 5,344 − 57 Simplify... [Show More] the expression above. Which of the following is correct? 5,277 5,283 5,287 D 5,288 Question 1 Explanation: The correct answer is (C). Remember that calculators are not permitted on the TEAS math test, so make sure you are able to subtract large numbers without using a calculator. (subtraction by regrouping) Question 2 CORRECT 3(x − 4) = 18 Solve the equation above. Which of the following is correct? x = 3/2 x = 22/3 x = 6 x = 10 Question 2 Explanation: The correct answer is (D). First divide both sides by 3: 3(x − 4) = 18 x − 4 = 18/3 x − 4 = 6 Then solve for x: x − 4 = 6 x = 6 + 4 x = 10 Question 3 The above is known as what type of graph? A Line Graph Scatterplot Bar Graph Histogram Question 3 Explanation: The correct answer is (B). The above graph is known as a scatterplot, which is a plot of points on x and y axes. In this case, each point would have an x value equal to the temperature in degrees Celsius, and a y value equal to the amount of money in dollars. Question 4 CORRECT (5x − 1) (3x + 2) Simplify the expression above. Which of the following is correct? A 15x2 − 7x + 3 15x2 + 7x − 2 15x2 + 7x − 3 15x2 − 7x − 2 Question 4 Explanation: The correct answer is (B). The “FOIL method” is the easiest way to remember how to multiply two-termed expressions. Multiply the First two terms, then the Outer two terms, then the Inner two terms, and then the Last two terms, then sum all four to arrive at the answer: 15x2 + 10x − 3x − 2 = 15x2 + 7x − 2 Question 5 CORRECT Timmy can usually make six paper airplanes in an hour. However, if he gets interrupted by his parents, he can only make four per hour. His friend John can make seven paper airplanes per hour. One day, Timmy and John decide to have a three-hour long contest to see who can make the most paper airplanes. During the contest, Timmy is interrupted once every hour. John also had to take a break and do chores for an hour. How many more paper airplanes does the winner make? A 1 2 3 4 Question 5 Explanation: The correct answer is (B). Because Timmy is interrupted during each hour, he can only make four paper airplanes per hour, multiplied by 3 hours, for a total of 12 airplanes. John makes seven paper airplanes during the two hours he works without chores, for a total of 14 airplanes. 14 airplanes minus 12 airplanes equals 2. Question 6 CORRECT If a car travels 360 kilometers in 5 hours, how far will it travel in 9 hours? 72 268 426 648 Question 6 Explanation: The correct answer is (D). Given that it took 5 hours to travel 360km, we can set up a ratio equation to figure out how far the car will travel in 9 hours. 360/5 = x/9 72 = x/9 72*9 = x x = 648 Question 7 CORRECT What degrees Fahrenheit is it at 30 degrees Celsius? Note: °F = (°C * 9/5) + 32 86 89 92 95 Question 7 Explanation: The correct answer is (A). Plug in °C = 30 into the given formula and solve for °F: °F = (°C * 9/5) + 32 °F = (30 * 9/5) + 32 °F = 54 + 32 °F = 86 Question 8 CORRECT A toy manufacturer makes 15,000 toys a year. The company randomly selects 300 of the toys to sample for inspection. The company discovers that there are 5 faulty toys in the sample. Based on the sample, how many of the 15,000 total toys are likely to be faulty? A 25 250 300 600 Question 8 Explanation: The sample indicates that 5 out of every 300 randomly selected toys will be faulty. Consequently, a proportion can be set up that relates the unknown number of faulty toys in the total number of toys to the ratio of faulty toys to the sample. Stated otherwise: T is the unknown number of faulty toys in the total. Multiply both sides by 15,000 and then divide the left hand side by 300 to solve for T: Question 9 At a comic book store, Robert purchased three comics for $2.65 each. If he paid with a $20 bill, how much change did he receive? A $10.95 $12.05 $13.15 $13.85 Question 9 Explanation: The correct answer is (B). Three comics at $2.65 would equal a total of $7.95. The change would equal $20 − $7.95 = $12.05. Question 10 CORRECT Simplify the expression above. Which of the following is correct? 14/54 22/67 29/72 D 18/126 Question 10 Explanation: The correct answer is (C). 7¼ can be expressed as 29/4. 29/4 x 1/18 = 29/(4 x 18) = 29/72. Question 11 CORRECT Express 5/8 as its closest rounded percentage. 56% 60% 63% D 66% Question 11 Explanation: The correct answer is (C). 5 ÷ 8 = 0.625, which equals 62.5%. Rounding up gives us 63%. Question 12 CORRECT Amanda wants to paint the walls of a room. She knows that each can of paint contains one gallon. A half gallon will cover a 55 square feet of wall. Each of the four walls is 10 feet high. Two of the walls are 10 feet wide and two of the walls are 15 feet wide. How many 1-gallon buckets of paint does Amanda need to buy in order to fully paint the room? A 4 5 9 10 Question 12 Explanation: The correct answer is (B). First, we must calculate the area of the walls Amanda wants to paint. Two of the walls are 10 x 10 and two of the walls are 10 x 15: 2 (10 x 10) = 200 2 (10 x 15) = 300 So the total square footage of the walls is 500. If a half gallon of paint will cover 55 square feet, then each gallon will cover 110 square feet. Four gallons would only cover 440 square feet. Five gallons will cover 550 square feet, which will be enough for all 500 square feet of walls. Question 13 CORRECT How many millimeters are there in 5 meters? A 500 5,000 50,000 500,000 Question 13 Explanation: The correct answer is (B). The prefix “milli-” means 1,000. There are 1,000 millimeters in 1 meter, so there are 5,000 millimeters in 5 meters. Question 14 CORRECT Kyra has a budget of $300 for her holiday spending. Kyra decides to buy shoes for her grandchildren. If each pair of shoes costs $40, and Kyra has ngrandchildren, which of the following inequalities represents Kyra’s budget constraint? 40n > 300 40 + n > 300 40 + n ≤ 300 40n ≤ 300 Question 14 Explanation: The correct answer is (D). If Kyra buys n pairs of shoes at a cost of $40 each, she pays $40n. Since she only has $300 to spend, $40nmust be less than or equal to $300: 40n ≤ 300 Question 15 CORRECT 2 − 8 ÷ (24 ÷ 2) = Simplify the expression above. Which of the following is correct? −6 −¾ 1 D 2 Question 15 Explanation: The correct answer is (C). Remember your order of operations: • Complete operations within parentheses first. • Calculate exponents. • Then multiply and divide in order from left to right. • Then add and subtract in order from left to right. 2 − 8 ÷ (24 ÷ 2) = 2 − 8 ÷ (16 ÷ 2) = 2 − 8 ÷ 8 = 2 − 1 = 1 Question 16 Which type of graph would best indicate the percentage of a school’s annual scholarship fund spent on freshman students? pie chart line graph scatter plot histogram Question 16 Explanation: The correct answer is (A). A pie chart represents percentages of a total, and would thus be the best graphic representation of a budget breakdown. Question 17 −1/4, π, 3/8, −0.2 Order the above list of numbers from least to greatest. Which of the following is correct? A −0.2, −1/4, 3/8, π −1/4, −0.2, 3/8, π −0.2, −1/4, π, 3/8 −1/4, −0.2, π, 3/8 Question 17 Explanation: The correct answer is (B). The smallest number is the greatest negative value: −1/4 (−0.25). The next smallest is −0.2 (−1/5). The largest value is π, or approximately 3.14. Question 18 Simplify: (7y2 + 3xy − 9) − (2y2 + 3xy − 5) 5y2 − 4 9y2 + 6xy − 14 5y2 + 4 5y2 + 6xy − 14 Question 18 Explanation: The correct answer is (A). When subtracting polynomials the first step is to distribute the negative sign through the parentheses. This changes the sign on each term inside the parentheses: 7y2 + 3xy − 9 − 2y2 − 3xy + 5 Arrange like terms next to each other (optional): 7y2 − 2y2+ 3xy − 3xy − 9 + 5 Combine like terms to compute the answer: 5y2 − 4 Question 19 | 2x − 5 | = 19 Which of the following is the solution set for the equation above? {−7, −12} {7, 12} {−7, 12} D {7, −12} Question 19 Explanation: The correct answer is (C). Absolute value equations can be rewritten in two ways to solve: 2x − 5 = 19 and 2x − 5 = −19. Solve both: 2x − 5 = 19 2x = 24 X = 12 2x − 5 = −19 2x = −14 x = −7 The two solutions and −7 and 12. Question 20 CORRECT If Maria left a $10.16 tip on a breakfast that cost $86.89, approximately what percentage was the tip? 12% 17% 25% 31% Question 20 Explanation: The correct answer is (A). The easiest way to answer this question is to round the numbers. Let’s say the tip is $10 and the total was $87. $10/$87 = approximately 11%. (A) is the closest answer to our approximation. Question 21 CORRECT A nurse working at a medical clinic earns $17.81 per hour. The nurse works three 8-hour shifts and one 12-hour shift every week, and is paid weekly. Weekly deductions are: federal tax $102.80, state tax $24.58, federal insurance $18.13, and family health insurance $52.15. What is the nurse's take-home pay each week? A $158.54 $443.50 $514.74 $641.16 Question 21 Explanation: The correct answer is (B). First you must calculate how many hours the nurse works each week. Three 8-hour shifts plus one 12-hour shift equals 36 hours per week. Beginning Salary = 36 x $17.81 = $641.16 Deductions = $102.80 + $24.58 + $18.13 + $52.15 = $197.66 Take-Home Pay = $641.16 − $197.66 = $443.50 Question 22 CORRECT How many imperial gallons are there in 1,400 liters? Note: 1 kiloliter = 220 imperial gallons 308 3,080 30,800 308,000 Question 22 Explanation: The correct answer is (A). There are 1,000 liters in 1 kiloliter: 1,400 liters = 1.4 kiloliters. 1.4 x 220 = 308 imperial gallons Question 23 CORRECT Derek purchased concert tickets in the month of June for $73, $66, $96, $17, and $66 dollars. Which of the following is an accurate estimate of the total amount he spent on concert tickets in June? A $300 $330 $360 $400 Question 23 Explanation: The correct answer is (B). The easiest way to make an estimate is to round each number so there is only one nonzero digit. Then you can easily add up the numbers: 73 ≈ 70 66 ≈ 70 96 ≈ 100 17 ≈ 20 66 ≈ 70 Adding these numbers together yields $330. Question 24 CORRECT 5y − 8 > 32 Solve the inequality above. Which of the following is correct? y > 8 y < 8 y > 6 y < 6 Question 24 Explanation: The correct answer is (A). To solve an inequality, simply treat the inequality symbol as if it’s an equals sign: 5y − 8 > 32 5y > 40 y > 8 Question 25 CORRECT There are 48 students studying foreign language at the community college. If the only two foreign languages offered are French and Spanish, and 28 students are studying French, which of the following represents the ratio of students studying Spanish to the total number of foreign language students? 2/7 1/2 1/3 5/12 Question 25 Explanation: The correct answer is (D). If there are 48 total, and 28 study French, then 20 study Spanish. The ratio of 20 to 48 = 10/24 = 5/12. Question 26 CORRECT What is 181.5% of 18? 3.267 14.67 32.67 D 3267 Question 26 Explanation: The correct answer is (C). First you must convert the fraction to a decimal by moving the decimal point 2 places to the left, which gives you 1.815. Then multiply this by 18. 1.815 x 18 = 32.67 Question 27 CORRECT Which of the following is equivalent to 0.0009? 0.0009% 0.009% 0.09% D 0.9% Question 27 Explanation: The correct answer is (C). In order to convert a decimal to a percent you need to move the decimal point two places to the right and add the percent symbol. Question 28 CORRECT A father is planning a birthday party for his son. He is expecting a total attendance of 7 adults and 13 children. Food costs will be $11.00 for each adult and $5.00 for each child. He will also need to spend $2.00 per child for party favors. Which of the following is the total cost of the birthday party? A $142.00 $168.00 $182.00 $192.00 Question 28 Explanation: The correct answer is (B). The cost for each adult will be $11.00. 7 x 11 = 77 The cost for each child will be $7.00 ($5.00 for food plus $2.00 for the party favors). 13 x 7 = 91 So the total cost will be 77 + 91, which is 168. Question 29 7 x 4 + (9 − 6) + 13 Simplify the expression above. Which of the following is correct? 34 37 41 44 Question 29 Explanation: The correct answer is (D). According to the order of operations, do what is inside the parenthesis first: 7 x 4 + (3) + 13 Next, move left to right, doing any multiplication or division: 28 + 3 + 13 Finally, move left to right, doing any addition or subtraction: 31 + 13 = 44 Question 30 Write the number 1906 in Roman numerals. MCMLXVIII MCMXVI MCMVI D XIXVI Question 30 Explanation: The correct answer is (C). In the Roman numeral system, M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, and I = 1. The ones, tens, hundreds and thousands must be treated as separate items. If a smaller item precedes a larger item, as in CM, it is treated as the difference of the two, so CM = 1000 − 100 = 900. 1000=M 900= CM 6=VI Question 31 A B D Once you are finished, click the button below.

Transmitting nerve impulses between the brain and the rest of the body. 4. Transporting important hormones released from glands to their sites of action. Correct Incorrect The circulatory system consists of the heart, blood vessels, lymph, lymph nodes, and blood. It circulates materials throughout the entire body, providing tissues and organs with nutrients and oxygen. It is also responsible for transporting hormones and removing waste. The nervous system is responsible for transmitting nerve impulses that originate in the brain and coordinate action in the rest of the body. Question 2 of 53 2. Question Which item below is NOT a disease of the digestive system? 1. Crohn’s disease. 2. Diabetes. 3. Ulcerative colitis. 4. Diverticulosis. Correct The digestive system helps the body process food. The stomach, mouth, and esophagus all participate in food digestion. Common diseases infecting the digestive system include Crohn’s disease, ulcerative colitis, and diverticulosis. Diabetes is a disease of the endocrine system, that impacts the release of insulin from the pancreas. Question 3 of 53 3. Question Which item below best describes the primary function of the nervous system? 1. The nervous system is the center of communication in the body. 2. The nervous system is primarily responsible for helping the body breathe. 3. The nervous system transports blood throughout the body. 4. The nervous system helps the body break down food. Correct The nervous system is the body’s communication center. The body uses the respiratory system to breathe, and blood is transported by the circulatory system. The digestive system breaks down food for the body. Question 4 of 53 4. Question Which of the following is NOT an element of the respiratory system? 1. Ribs. 2. Trachea. 3. Diaphragm. 4. Alveoli. Correct The respiratory system uses the lungs, diaphragm, trachea, alveoli and bronchi to help the body distribute oxygen and remove carbon dioxide. While the ribs contain and protect many of these elements, the ribs are part of the musculoskeletal system, which is responsible for providing structure, stability and protection to the internal organs. Question 5 of 53 5. Question Which of the following cells is NOT part of the immune system? 1. Neurons. 2. Dendritic cells. 3. Macrophages. 4. Mast cells. Correct The immune system helps protect the body from bacteria, viruses, infections, and other elements that could cause illness. Depending on the foreign element that enters the body, different cells respond to attack the foreign element. Cells that contribute to this protection and response include leukocytes, or white blood cells (eosinophils, basophils, natural killer (NK) cells, and mast cells), and phagocytic cells (dendritic cells, macrophages and neutrophils) in addition to cells of adaptive immunity (B cells and T cells) which are produced in the bone marrow. A neuron is a nerve cell that is central to the nervous system and transmits nerve impulses. Question 6 of 53 6. Question Which of the following is NOT one of the major types of bones in the human body? 1. Dense bone. 2. Long bone. 3. Short bone. 4. Irregular bone. Correct The human body has five types of bones: long bones, short bones, irregular bones, flat bones, and sesamoid bones. While bones may be dense, this is not a major category of bones in the body. Question 7 of 53 7. Question Which of the following bone types is embedded in tendons? 1. Long bones. 2. Sesamoid bones. 3. Flat bones. 4. Vertical bones. Correct Sesamoid bones are embedded in tendons. Vertical bones, is not a major bone type. Long bones contain a long shaft, and flat bones are thin and curved. Question 8 of 53 8. Question Two nursing students will be completing a scientific experiment measuring the mass of chewed gum after one-minute chewing increments. Which lab equipment will the students most likely use? 1. Triple beam balance. 2. Anemometer. 3. Hot plate. 4. Microscope. Correct A triple beam balance would be used to measure the mass (in grams) of the gum in this experiment. An anemometer is used to measure wind speed. A hot plate is used to heat liquids. A microscope is used to magnify microscopic particles or organisms. Question 9 of 53 9. Question Which of the following is not a product of respiration? 1. Carbon dioxide. 2. Water. 3. Oxygen. 4. ATP. Correct In respiration, the human inhales air, consisting of oxygen, and then produces energy (ATP) and exhales nitrogen, carbon dioxide, and water (in the form of vapor). While oxygen is a main component of the respiratory system’s process, it is not produced by the respiratory system. Rather, it is utilized and distributed throughout the body, and then what is not absorbed, is exhaled back into the environment. Question 10 of 53 10. Question Of the following, the blood vessel containing the least-oxygenated blood is: 1. the aorta. 2. the vena cava. 3. the pulmonary artery. 4. the capillaries. Correct The pulmonary artery carries oxygen-depleted blood from the heart to the lungs, where CO2 is released and the supply of oxygen is replenished. This blood then returns to the heart through the pulmonary vein, and is carried through the aorta and a series of branching arteries to the capillaries, where the bulk of gas exchange with the tissues occurs. Oxygen-depleted blood returns to the heart through branching veins (the femoral veins bring it from the legs) into the vena cava, which carries it again to the heart. Since the pulmonary artery is the last step before replenishment of the blood’s oxygen content, it contains the blood which is the most oxygen depleted. Question 11 of 53 11. Question Which layer of the heart contains striated muscle fibers for contraction of the heart? 1. Pericardium. 2. Epicardium. 3. Endocardium. 4. Myocardium. Correct The myocardium is the layer of the heart that contains the muscle fibers responsible for contraction (Hint: myo- is the prefix for muscle). The endocardium and epicardium are the inner and outer layers of the heart wall, respectively. The pericardium is the sac in which the heart sits inside the chest cavity. Question 12 of 53 12. Question Which blood vessel carries oxygenated blood back to the heart? 1. Pulmonary vein. 2. Pulmonary artery. 3. Aorta. 4. Superior vena cava. Correct While generally speaking, veins carry deoxygenated blood and arteries carry oxygenated blood, in this case, the pulmonary veins carry oxygenated blood from the lungs to the left side of the heart and the pulmonary arteries carry deoxygenated blood from the right side of the heart to the lungs. The aorta, takes oxygenated away from the left side of the heart and distributes it throughout the body. The superior vena cava returns unoxygenated blood back to the right side of the heart, to then be distributed through the lungs and reoxygenated. Question 13 of 53 13. Question Mrs. Jones’s class conducted an experiment on the effects of sugar and artificial sweetener on the cookie recipe’s overall color when baked. What would be the independent variable in the cookie experiment? 1. The students should use the same ingredients in both recipes, but bake the cookies with sugar at 450 degrees and those with artificial sweetener at 475 degrees. They should increase the baking time on the artificial sweetener cookies, since the package instructs them to do so. 2. The students should use the same ingredients in both recipes, but increase the baking time on the artificial sweetener cookies, since the package instructs them to do so. 3. The students should use the same ingredients, same baking temperatures, and same baking times for both recipes. 4. The students should use the same ingredients and baking times in both recipes, but bake the cookies with sugar at 450 degrees and the artificial sweetener cookies at 475 degrees. Correct The independent variable is the variable that is changed in the experiment in order to determine its effect on the dependent variable or the outcome of the experiment. The dependent variable results from the experimenter making only one change to an experiment that can be repeated with the same results. Mrs. Jones’s class was comparing the effects of sugar and artificial sweetener on the overall color of cookies once they are baked; thus, the one thing that should be changed in the experiment is the sugar and artificial sweetener in the recipe. All of the other ingredients stay the same. For the experiment to be valid and not influenced by any other variables, the students should keep the temperature and baking time the same, as these could affect the color of the cookies as well. Question 14 of 53 14. Question Which part of the cell is often called the cell “power house” because it provides energy for cellular functions? 1. Nucleus. 2. Cell membrane. 3. Mitochondria. 4. Cytoplasm. Correct Mitochondria are often called the power house of the cell because they provide energy for the cell to function. The nucleus is the control center for the cell. The cell membrane surrounds the cell and separates the cell from its environment. Cytoplasm is the thick fluid within the cell membrane that surrounds the nucleus and contains organelles. Question 15 of 53 15. Question What function do ribosomes serve within the cell? 1. Ribosomes are responsible for cell movement. 2. Ribosomes aid in protein synthesis. 3. Ribosomes help protect the cell from its environment. 4. Ribosomes have enzymes that help with digestion. Correct Ribosomes are organelles that help synthesize proteins within the cell. Cilia and flagella are responsible for cell movement. The cell membrane helps the cell maintain its shape and protects it from the environment. Lysosomes have digestive enzymes. Question 16 of 53 16. Question What is the most likely reason that cells differentiate? 1. Cells differentiate to avoid looking like all the cells around them. 2. Cells differentiate so that simple, non-specialized cells can become highly specialized cells. 3. Cells differentiate so that multicellular organisms will remain the same size. 4. Cells differentiate for no apparent reason. Correct Cells differentiate so that simple, less specialized cells can become highly specialized cells. For example, humans are multicellular organisms who undergo cell differentiation numerous times. Cells begin as simple zygotes after fertilization and then differentiate to form a myriad of complex tissues and systems before birth. Question 17 of 53 17. Question How is meiosis similar to mitosis? 1. Both produce daughter cells that are genetically identical. 2. Both produce daughter cells that are genetically different. 3. Both occur in humans, animals, and plants. 4. Both occur asexually. Correct Both meiosis and mitosis occur in humans, animals, and plants. Mitosis produces cells that are genetically identical, and meiosis produces cells that are genetically different. Only mitosis occurs asexually. Question 18 of 53 18. Question In the suburban neighborhood of Northwoods, there have been large populations of deer, and residents have complained about them eating flowers and garden plants. What would be a logical explanation, based on observations, for the large increase in the deer population over the last two seasons? 1. Increased quantity of food sources in surrounding areas. 2. Decreased population of a natural predator in Northwoods. 3. Deer migration from surrounding areas. 4. Increase in hunting licenses sold. Correct A decrease in a natural predator, such as a wolves, coyotes, bobcat, or wild dogs, would allow the population to become out of control. In a population of deer that has increased, there would be a natural decrease in a food source for the nutritional needs for the animals in surrounding areas. Although deer have been known to share a human’s developed habitat, it is often forced by reduced territory and food sources. An increase in hunting licenses would be used by local officials to try to control the population, helping to decrease the number of adults of breeding age. Question 19 of 53 19. Question How do DNA and RNA function together as part of the human genome? 1. DNA carries genetic information from RNA to the cell cytoplasm. 2. RNA carries genetic information from DNA to the cell cytoplasm. 3. DNA and RNA carry genetic information from the cell nucleus to the cytoplasm. 4. DNA and RNA do not interact within the cell. Correct DNA is the primary carrier of genetic information in most cells. RNA serves as a messenger that transmits genetic information from DNA to the cytoplasm of the cell. Question 20 of 53 20. Question The majority of nutrient absorption occurs in the: 1. mouth. 2. stomach. 3. small intestine. 4. large intestine. Correct Food enters the digestive system through the mouth and proceeds down to the stomach after mastication by the teeth. Once in the stomach, enzymes are secreted that begin to digest the specific substances in the food (proteins, carbohydrates, etc.). Next, the food passes through to the small intestine where the nutrients are absorbed and then into the large intestine where extra water is absorbed. Question 21 of 53 21. Question What process should the DNA within a cell undergo before cell replication? 1. The DNA should quadruple so that daughter cells have more than enough DNA material after cell division. 2. The DNA should triple so that daughter cells have three times the amount of DNA material after cell division. 3. The DNA should replicate so that daughter cells have the same amount of DNA material after cell division. 4. The DNA should split so that daughter cells have half the amount of DNA material after cell division. Correct After cell division, the daughter cells should be exact copies of the parent cells. Therefore, the DNA should replicate, or make an exact copy of itself, so that each daughter cell will have the full amount of DNA. Question 22 of 53 22. Question What basic molecular unit enables hereditary information to be transmitted from parent to offspring? 1. Genes. 2. Blood. 3. Traits. 4. Cell. Correct Genes are the molecular units that enable parents to pass hereditary traits on to their offspring. The blood, organs, cells and hair all contain the genes that makeup the offspring, but these are not basic molecular units. Question 23 of 53 23. Question Which statement most accurately compares and contrasts the structures of DNA and RNA? 1. Both DNA and RNA have 4 nucleotide bases. Three of the bases are the same but the fourth base is thymine in DNA and uracil in RNA. 2. Both DNA and RNA have the same 4 nucleotide bases. However, the nucleotides bond differently in the DNA when compared to RNA. 3. Both DNA and RNA have 6 nucleotide bases. However, the shape of DNA is a triple helix and the shape of RNA is a double helix. 4. Both DNA and RNA have a double helix structure. However, DNA contains 6 nucleotide bases and RNA contains 4 nucleotide bases. Correct Both DNA and RNA are made up of 4 nucleotide bases. Both DNA and RNA contain cytosine, guanine, and adenine. However, DNA contains thymine and RNA contains uracil. Choice B is incorrect because DNA and RNA do not have the same 4 nucleotides, and choices C and D are incorrect because neither DNA nor RNA contains 6 nucleotides. Furthermore, DNA has a double helix structure, and RNA has a single helix structure. Question 24 of 53 24. Question Which of the following characteristics is part of a person’s genotype? 1. Brown eyes that appear hazel in the sunlight. 2. CFTR genes that causes cystic fibrosis. 3. Black hair that grows rapidly. 4. Being a fast runner. Correct The genotype describes a person’s genetic makeup. The phenotype describes a person’s observable characteristics. Among the choices, the CFTR gene refers to genetic makeup while the other choices all describe traits that are observable. Question 25 of 53 25. Question Let B represent the dominant gene for a full head of hair, and let b represent the recessive gene for male pattern baldness. The following Punnett square represents the offspring of two people with recessive genes for baldness. /> According to the Punnett square, which selection includes all outcomes that would produce an offspring with male pattern baldness? 1. Possibility 1. 2. Possibility 4. 3. Possibilities 1, 2, and 3. 4. Possibilities 2, 3, and 4. Correct The complete Punnett square is shown below. Because male pattern baldness is a recessive gene, the offspring would need the bb gene combination in order to inherit this trait. Possibility 4 corresponds to the bb gene combination. Question 26 of 53 26. Question Let B represent the dominant gene for a full head of hair, and let b represent the recessive gene for male pattern baldness. The following Punnett square represents the offspring of two people with recessive genes for baldness. /> According to the Punnett square, which selection includes all outcomes that would produce an offspring with a full head of hair? 1. Possibility 1. 2. Possibility 4. 3. Possibilities 1, 2, and 3. 4. Possibilities 2, 3, and 4. Correct The complete Punnett square is shown below. Because male pattern baldness is recessive, the offspring would need the bb gene combination in order to inherit this trait. Therefore, any offspring with the B gene will have a full head of hair. Possibilities 1, 2, and 3 all have the B gene. Question 27 of 53 27. Question Where is the interstitial fluid found? 1. In the blood and lymphatic vessels. 2. In the tissues around cells. 3. In the cells. 4. In the ventricles of the brain. Correct Interstitial fluid is found in the tissues around the cells; intracellular fluid is found within the cells. Fluid in the ventricles of the brain and down into the spinal cord is called cerebrospinal fluid. Cerebrospinal fluid bathes these sensitive tissues in a fluid that helps to protect them. Blood and lymph are the fluids that carry nutrients, oxygen, waste, and lymph material throughout the body. Question 28 of 53 28. Question Which type of cell secretes antibodies? 1. Bacterial cell. 2. Viral cell. 3. Lymph cell. 4. Plasma cells. Correct Plasma cells secrete antibodies. These cells, also known as plasmacytes, are located in lymphoid tissue. Antibodies are only secreted in response to a particular stimulus, usually the detection of an antigen in the body. Antigens include bacteria, viruses, and parasites. Once released, antibodies bind to the antigen and neutralize it. When faced with a new antigen, the body may require some time to develop appropriate antibodies. Once the body has been exposed to an antigen, however, it does not forget how to produce the correct antibodies. Question 29 of 53 29. Question Chemical C is a catalyst in the reaction between chemical A and chemical B. What is the effect of chemical C? 1. Chemical C increases the rate of the reaction between A and B. 2. Chemical C decreases the rate of the reaction between A and B. 3. Chemical C initiates the reaction between A and B. 4. Chemical C converts A from a base to an acid. Correct A catalyst increases the rate of a chemical reaction without becoming part of the net reaction. Therefore, chemical C increases the rate of the reaction between A and B. The catalyst does not change the chemicals within the reaction or initiate the reaction itself. Question 30 of 53 30. Question What type of molecules are enzymes? 1. Water molecules. 2. Protein molecules. 3. Tripolar molecules. 4. Inorganic molecules. Correct Enzymes are protein molecules produced by living organisms. Enzymes serve as catalysts for certain biological reactions. Question 31 of 53 31. Question Which structure controls the hormones secreted by the pituitary gland? 1. Hypothalamus. 2. Adrenal gland. 3. Testes. 4. Pancreas. Correct The hypothalamus controls the hormones secreted by the pituitary gland. This part of the brain maintains the body temperature and helps to control metabolism. The adrenal glands, which lie above the kidneys, secrete steroidal hormones, epinephrine, and norepinephrine. The testes are the male reproductive glands, responsible for the production of sperm and testosterone. The pancreas secretes insulin and a fluid that aids in digestion. Question 32 of 53 32. Question Where does gas exchange occur in the human body? 1. Alveoli. 2. Bronchi. 3. Larynx. 4. Pharynx. Correct Gas exchange occurs in the alveoli, the minute air sacs on the interior of the lungs. The bronchi are large cartilage-based tubes of air; they extend from the end of the trachea into the lungs, where they branch apart. The larynx, which houses the vocal cords, is positioned between the trachea and the pharynx; it is involved in swallowing, breathing, and speaking. The pharynx extends from the nose to the uppermost portions of the trachea and esophagus. In order to enter these two structures, air and other matter must pass through the pharynx. Question 33 of 53 33. Question All of the following are parts of the respiratory system EXCEPT the: 1. trachea. 2. bronchi. 3. esophagus. 4. larynx. Correct The esophagus is the only structure that is not part of the respiratory system, it is part of the digestive system. The larynx houses the voice box; it also acts as a passageway for air to travel into the lungs. The trachea connects the larynx to the lungs. The trachea splits into the right and left bronchi, which divide into smaller passageways called the bronchioles. Question 34 of 53 34. Question What lab equipment would most likely be used to measure a liquid solution? 1. Flask. 2. Triple beam balance. 3. Graduated cylinder. 4. Test tube. Correct In order to have accurate measurements, the use of a graduated cylinder would be the best measurement equipment for a liquid solution. A triple beam balance measures the weight of an object in grams. A flask and a test tube are used to contain a liquid while being heated or stored. Question 35 of 53 35. Question An atom has 5 protons, 5 neutrons, and 6 electrons. What is the electric charge of this atom? 1. Neutral. 2. Positive. 3. Negative. 4. Undetermined. Correct The atom is negatively charged. Neutrons have no charge. Protons have positive charge and electrons have negative charge equal in magnitude to the positive charge of the proton. Because the atom has more electrons than protons, the atom has a negative charge. Question 36 of 53 36. Question All of the following are components of the genitourinary system EXCEPT: 1. the kidneys. 2. the urethra. 3. the rectum. 4. the bladder. Correct The genitourinary system is responsible for removing waste from the body through urine. Components include two kidneys, two ureters that drain the urine from the kidney to the bladder, and the urethra that drains urine from the bladder out of the body. The rectum is the last section of the large intestine, and part of the digestive system. Question 37 of 53 37. Question Which of the following best describes the structures found underneath each rib in descending order? 1. Vein, nerve, artery. 2. Artery, vein, nerve. 3. Vein, artery, nerve. 4. Nerve, vein, artery. Correct The neurovascular structure found under each rib in descending order is the vein, artery, and nerve. When a procedure such as a thoracocentesis or chest tube needs to be performed, the medical professional should aim for directly over the rib in order to avoid damaging to these structures. Question 38 of 53 38. Question The table below contains information from the periodic table of elements. " /> Which pattern below best describes the elements listed in the table? 1. The elements are arranged in order by weight with H being the heaviest atom and Be being the lightest atom. 2. The elements are arranged in order by electron charge with H having the most electrons and Be having the fewest electrons. 3. The elements are arranged in order by protons with H having the most protons and Be having the fewest protons. 4. The elements are arranged in order by protons with H having the fewest protons and Be having the most protons. Correct The atomic number equals the number of protons in an atom. Since Be has an atomic number of 4, it has 4 protons. H has the fewest protons, as denoted by its atomic number of 1. Question 39 of 53 39. Question Which of the following is true regarding the primary function of the spleen? 1. It produces bile to emulsify fats. 2. It filters microorganisms and other foreign substances from the blood. 3. It helps control blood glucose levels and regulates blood pressure. 4. It regulates blood clotting factors. Correct The spleen’s job is to filter the blood by removing dead or dying red blood cells as well as microorganisms. In humans it is found in the left upper quadrant of the abdomen lateral to the liver. Question 40 of 53 40. Question The process of changing from a liquid to a gas is called ________. 1. freezing 2. condensation 3. vaporization 4. sublimation Correct Vaporization is the process of changing from a liquid to a gas. For instance, water vaporizes when boiled to create steam. Freezing is the process of changing from a liquid to a solid. Condensation describes changing from a gas to a liquid, and sublimation is the process of changing from a solid to a gas. Incorrect Question 41 of 53 41. Question A nurse wants to investigate how different environmental factors affect her patients’ body temperatures. Which tool would be the most helpful when the nurse conducts her investigation? 1. Scale. 2. Yard stick. 3. Thermometer. 4. Blood pressure monitor. Correct The nurse wants to investigate her patients’ body temperatures. A thermometer is the only tool in the list that will help measure the temperature of a person’s body. Question 42 of 53 42. Question A scientific study has over 2000 data points. Which of the following methods is most likely to help the researcher gain usable information from the data? 1. Use statistical analysis to understand trends in the data. 2. Look at each individual data point, and try to create a trend. 3. Eliminate 90% of the data so that the sample size is more manageable. 4. Stare at the data until a pattern pops out. Correct The researcher should use statistical analysis to understand trends in the data. Different statistics tools can help manage and examine large data sets. The researcher would probably miss important correlations by looking at the individual data points, and eliminating most of the data would defeat the purpose of conducting the study. Simply staring at the data would not be helpful. Question 43 of 53 43. Question Many years ago, people believed that flies were created from spoiled food because spoiled food that was left out in the open often contained fly larvae. A scientist placed fresh food in a sealed container for an extended period of time. The food spoiled, but no fly larvae were found in the food that was sealed. Based on this evidence, what is the most likely reason that spoiled food left out in the open often contained fly larvae? 1. The spoiled food evolved into fly larvae. 2. Since the food was left out in the open, flies would lay eggs in the food. 3. Fly larvae were spontaneously generated by the spoiled food. 4. People only imagined they saw fly larvae in the spoiled food. Correct Based on the evidence, the most likely explanation for fly larvae in the spoiled food is that flies laid their eggs in the food. When the food was left out in the open, the flies had access to it and laid their eggs. However, when the food was in a sealed container, the flies could not lay their eggs in the food. Hence, the spoiled food in the sealed container had no fly larvae. Question 44 of 53 44. Question The average life expectancy in the 21st century is about 75 years. The average life expectancy in the 19th century was about 40 years. What is a possible explanation for the longer life expectancy in the present age? 1. Advances in medical technology enable people to live longer. 2. Knowledge about how basic cleanliness can help avoid illness has enabled people to live longer. 3. The creation of various vaccines has enabled people to live longer. 4. All of the statements above offer reasonable explanations for longer life expectancy. Correct Longer life expectancy could be explained by any or all of the alternatives presented. Advances in medical technology, basic cleanliness, and vaccines could all help people live longer in the 21st century. Question 45 of 53 45. Question A doctor needs to convince his boss to approve a test for a patient. Which statement below best communicates a scientific argument that justifies the need for the test? 1. The patient looks like he needs this test. 2. The doctor feels that the patient needs this test. 3. The patient’s symptoms and health history suggest that this test will enable the correct diagnosis to help the patient. 4. The patient has excellent insurance that will pay for several tests, and the doctor would like to run as many tests as possible. Correct A scientific argument should be based on measurable and observable facts such as the patient’s current symptoms and health history. Discussing the patient’s appearance or the doctor’s feelings does not communicate a scientific argument. While insurance may be a factor in most healthcare systems, the status of the patient’s insurance does not communicate a scientific argument that justifies the need for the test. Question 46 of 53 46. Question Which of the following is a protein that interferes with virus production? 1. Lysozyme. 2. Prion. 3. Interferon. 4. Keratin. Correct Interferons are members of a larger class of proteins called cytokines. Cytokines are specialized proteins that carry signals between cells. Interferons are proteins that are produced by cells infected by pathogens such as viruses. They signal neighboring cells to produce antiviral proteins which help prevent the spread of infection. Incorrect Question 47 of 53 47. Question Which of the following does not contain blood vessels? 1. Hyperdermis. 2. Hypodermis. 3. Dermis. 4. Epidermis. Correct Humans have three layers of skin called the epidermis, the dermis, and subcutaneous fat. Epidermis is the top layer of the skin, the dermis is the second layer, and subcutaneous makes up the bottom layer. The epidermis does not contain blood vessels. Question 48 of 53 48. Question What structure is responsible for the release of hormones that stimulate the gonads during puberty? 1. Hypothalamus. 2. Midbrain. 3. Basal ganglia. 4. Hippocampus. Correct The hypothalamus is a tiny gland at the base of the brain. It helps regulate temperature, sleep, emotions, sexual function and behavior. During puberty it secretes hormones that stimulate the gonads which initiate sexual development. Question 49 of 53 49. Question Which of the following structures has the lowest blood pressure? 1. Arteries. 2. Arteriole. 3. Venule. 4. Vein. Correct Of the given structures, veins have the lowest blood pressure. Veins carry oxygen-poor blood from the outlying parts of the body to the heart. An artery carries oxygen-rich blood from the heart to the peripheral parts of the body. An arteriole extends from an artery to a capillary. A venule is a tiny vein that extends from a capillary to a larger vein. Question 50 of 53 50. Question Which of the heart chambers is the most muscular? 1. Left atrium. 2. Right atrium. 3. Left ventricle. 4. Right ventricle. Correct Of the four heart chambers, the left ventricle is the most muscular. When it contracts, it pushes blood out to the organs and extremities of the body. The right ventricle pushes blood into the lungs. The atria, on the other hand, receive blood from the outlying parts of the body and transport it into the ventricles. The basic process works as follows: Oxygen-poor blood fills the right atrium and is pumped into the right ventricle, from which it is pumped into the pulmonary artery and on to the lungs. In the lungs, this blood is oxygenated. The blood then reenters the heart at the left atrium, which when full pumps into the left ventricle. When the left ventricle is full, blood is pushed into the aorta and on to the organs and extremities of the body. Question 51 of 53 51. Question Which part of the brain interprets sensory information? 1. Cerebrum. 2. Hindbrain. 3. Cerebellum. 4. Medulla oblongata. Correct The cerebrum is the part of the brain that interprets sensory information. It is the largest part of the brain. The cerebrum is divided into two hemispheres, connected by a thin band of tissue called the corpus callosum. The cerebellum is positioned at the back of the head, between the brain stem and the cerebrum. It controls both voluntary and involuntary movements. The medulla oblongata forms the base of the brain. This part of the brain is responsible for blood flow and breathing, among other things. Question 52 of 53 52. Question A vaccination is a way of acquiring which type of immunity? 1. Passive natural immunity. 2. Active natural immunity. 3. Active artificial immunity. 4. Passive artificial immunity. Correct A vaccination is a way of acquiring active artificial immunity, where an antigen is deliberately introduced into an individual to stimulate the immune system. Vaccines contain dead or dying pathogens which are not enough to cause an infection, but allow the immune system to “remember” the pathogen and become immune to it. Question 53 of 53 53. Question Which component of the nervous system is responsible for lowering the heart rate? 1. Central nervous system. 2. Sympathetic nervous system. 3. Parasympathetic nervous system. 4.
