1. An organism with chloroplasts in its cells is probably.
a.
... [Show More] a heterotroph
b. an autotroph
c. an herbivore
d. a primary consumer Correct answer- B: Organisms that have chloroplasts
in their cells carry on photosynthesis and are therefore autotrophs.
Autotrophs make their own food.
2. What property of water allows someone to fill a glass slightly above the rim
without the water flowing over?
a. specific gravity
b. capillarity
c. opacity
d. surface tension Correct answer- D: Water molecules are polar. Due to the
fact that O2 draws the electrons in the molecule toward itself.
3. The spaces between neurons are called?
a. synapses
b. dendrites
c. inter-neurons
d. cell gaps Correct answer- A: An impulse travels down the axon of a
neuron and reaches the terminus. There, chemicals are released in
response, which travel across the synapse to the next neuron. Thus the
impulse is transmitted to the next neuron.
4. Which Group of chemicals is not normally found in most living things?
a. carbohydrates
b. proteins
c. silicates
d. nucleic acids Correct answer- C: Carbohydrates, proteins, and nucleic
acids (RNA and DNA) are all very important chemicals in living things.
5. The alimentary canal is associated with the?
a. spinal cord
b. digestive system
c. urinary tract

d. birth canal Correct answer- B: The alimentary canal begins at the mouth
and ends at the anus.
6. The numerous villi in the small intestine serve to?
a. secrete enzymes for digestion
b. absorb water from dissolved foods
c. secrete hydrochloric acid to dissolve food
d. provide greater surface for absorption Correct answer- D: The villi are tiny
projections in the small intestine that increase the total surface area of the
intestine for absorption of digested nutrients.
7. As light passes obliquely from air to water, it is bent. This bending is called?
a. diffraction
b. reflection
c. refraction
d. dispersion Correct answer- C: Refraction is the bending of light as it
passes obliquely from one medium to another.
8. Which of the following organelles is not involved in protein synthesis?
a. ribsome
b. mitochondrion
c. rough endoplasmic reticulum
d. nucleus Correct answer- D: The nucleus contains DNA. The ribosomes,
located on the rough endoplasmic reticulum, are the site for protein
synthesis.
9. To be absorbed by cells, proteins must be changed to?
a. amino acids
b. sucrose
c. fatty acids
d. glycerol Correct answer- A: Amino acids are the end products of protein
digestion and are small enough to be absorbed.
10.A neuron that transmits impulses from the receptors to the spinal cord is called?
a. motor neuron
b. an associative neuron
c. an interneuron
d. a sensory neuron Correct answer- D: A sensory neuron conveys a
message from a sensory organ to the spinal cord, which transmits the
message via a motor neuron to the effector muscle.

11.Which group of organisms help prevent the accumulation of organic wastes in
nature?
a. rabbits
b. mosses
c. bacteria
d. ferns Correct answer- C: Bacteria comprise the decomposer portion of the
food chain.
12.As the eardrum is made to vibrate more rapidly, the sound is perceived as?
a. louder in intensity
b. softer in intensity
c. higher in pitch
d. lower in pitch Correct answer- C: High-pitch sounds are heard when the
receptor cells closer to the oval window are stimulated, and low-pitch
sounds result from the stimulation of the cells that are farther down the
cochlea.
13.In a field of pure white asters, a grower noticed a single blue aster. How could
the grower test whether this change affected the gamete-producing cells of the
plant?
a. self-pollinate the flower, and plant the resulting seeds
b. examine the blue petals under an electron microscope
c. preform a chemical analysis to find the nature of the blue pigment
d. preform vegetative propagation on a cutting of the plant Correct answerA: Remember that during a phase change from liquid to gas the
temperature remains constant at 100C.
