SFSU BIO 230 FINAL EXAM QUESTIONS WITH
SOLUTIONS
How does strangulation and hyperventilation disrupt homeostasis?-correct-
answer-Strangulation/Hypoxia: disrupts homeostasis b/c oxygen doesn't get to
the cells (low concentration of O), so we can't do cellular respiration.
Hyperventilation/Hypocapnia disrupts homeostasis b/c a low concentration of Co2
causes your pH levels to raise & feel like you don't need to breathe.
Why is the choking game so dangerous (think molecules!)?-correct-answer-It kills
your brain cells and disrupts your motor skills
many diseases are caused or caused by a-correct-answer-disruption in
homeostasis
maintaining homeostasis is a ____________ event and requires _________?-
correct-answer-1. Active
2. Energy
,2|Page
Homeostasis is achieved through cooperation of-correct-answer-multiple organ
systems, including the nervous and endocrine system
which part of cellular respiration is water produced?-correct-answer-Electron
transport chain
Cellular water balance is achieved by-correct-answer-osmosis
water balance is achieved by-correct-answer-regulating the uptake, generation,
and elimination of water
most of the water in our body is located-correct-answer-inside our cells
hypertonic-correct-answer-hypertonic refers to the one with the greater solute
concentration
HYPOTONIC-correct-answer-hypotonic refers to the one with the lower solute
concentration
, 3|Page
Drinking water or other solutions low in solutes (like Gatorade)-correct-answer-
decreases the concentration of solutes in
blood.
When the blood has less solute-correct-answer-it is HYPOTONIC compared to cells
throughout the body.
The pretense of microvilli-correct-answer-increase the surface area (structure)
and facilitate the absorption of food and water (function)
After ingestion, water diffuses into cells of the small intestine microvilli. Where is
the next place the water goes on its way to your bloodstream?-correct-answer-
Into the interstitial space between microvilli cells
Suppose you could check your collecting duct permeability. Then you drink two
big glasses of water. Half an hour later, you check the permeability again. On the
second check, the permeability is most likely to be:-correct-answer-Lower
