d) epiglottis
(Test 1) - Answer- d)
... [Show More] epiglottis
"the epiglottis covers the trachea during swallowing, thus preventing food from
entering the airway"
?= aka the windpipe
- is a cylindrical portion of the respiratory tract that joins the larynx with the lungs
(Test 1) - Answer- Trachea
?= connects the throat to the stomach
- when someone swallows, this contracts to force the food down into the stomach
- like other structures in the respiratory system, this structure secretes mucus for
lubrication
(Test 1) - Answer- Esophagus

b) cilia
c) trachea
d) alveoli
(Test 1) - Answer- b) cilia
(READ STARRED BULLET POINT****)
- the cilia are the tiny hairs in the respiratory system that are responsible for

On average, how many neutrons does one atom of bromine (Br) have?
NOTE:
- atomic #= 35
- atomic mass= 79.9
a) 35
b) 44.90
c) 45
d) 79.90
(Test 1) - Answer- b) 44.90
to determine the number of neutrons (n), subtract the atomic number (35) from the
atomic mass (79.9)
79.9 - 35 = 44.90
On average, how many protons does one atom of zinc (Zn) have?
NOTE:
- atomic # = 30
- atomic mass = 65.39
a) 30
b) 35
c) 35.39
d) 65.39
(Test 1) - Answer- a) 30
- The number of protons is the atomic number
- The number of protons is the same for every atom of a given element
What is the name of the process in the lungs by which oxygen is transported from
the air to the blood?
a) osmosis
b) diffusion
c) dissipation
d) reverse osmosis
(Test 1) - Answer- b) diffusion
cannot be osmosis- osmosis is the movement of a solution from an area of low conc
to an area of higher conc through a permeable membrane
cannot be dissipation- dissipation is any wasteful consumption or use
cannot be reverse osmosis- a process for purifying a solution by forcing it through a
membrane that blocks only certain pollutants... [Show Less]
