Biology 1500 Exam 5 – MIZZOU Questions And
Answers |Latest 2025 | Guaranteed Pass
Find out the approximate elevation of Mt. Everest in meters - Answer✔Between 8,800 and
8,900
According to the article, roughly what percentage of people who climb Mt. Everest die there? -
Answer✔10
The characteristic of the 'death zone' that prevents people from remaining there for more than
48 hours is - Answer✔insufficient oxygen
- up there, the oxygen is only 1/3 of the sea level value
- the body will use up its store of oxygen faster than breathing can replenish it
- grabbing oxygen is the problem, not the release of it
The bar-headed geese migrate between - Answer✔India and Mongolia .
What is remarkable about the migration of the bar-headed geese? - Answer✔remarkable
because on their journey, they are able to fly above Mt. Everest, which is at a very high altitude
- this high altitude that Bar-Headed Geese can fly over, is at an altitude where humans struggle
to survive.
According to the article, the geese achieve this feat by - Answer✔- acquire oxygen very
efficiently.
- they also have more capillaries and more efficient red blood cells, meaning their bodies can
deliver more oxygen to muscle cells fast -> muscles have more mitochondria (produces energy)
- hyperventilation (without feeling dizzy) to increase the net quantity of oxygen in the blood

tidal volume - Answer✔The amount of air that moves in and out of the lungs per breath when
breathing normally
vital capacity - Answer✔- The maximum amount of air that can be inhaled or exhaled during a
respiratory cycle
- The greatest volume of air that be expelled from the lungs after taking the deepest breath
possible
alveoli - Answer✔- Gas exchange happens here
- Tiny air sacs of the lungs that allow for rapid gas exchange (close contact of air and blood)
- Where the lungs and the blood exchange oxygen and carbon dioxide during the process of
breathing in and out - their presence increases the surface area of the lung to maximize gas
exchange
O2 partial pressure - Answer✔portion of total gas pressure exerted by oxygen rather than by
other gases in the mixture
residual volume - Answer✔the amount of air left in the lungs after exhaling - this volume is
never exchanged (1-1.5)
ventilation - Answer✔the movement of air through the conducting passages between the
atmosphere and the lungs
--> Occurs via inhalation when air enters the body through the nasal cavity - air passes through
the nasal cavity and is then warmed to body temperature.
gas exchange - Answer✔movement of oxygen from air into blood, and of co2 from blood into
air
The functions of the mammalian respiratory system are to supply ...... to the cells, which they
need for performing the process of ......, and to rid the body of ....... that was produced by cells
as a byproduct of ..... - Answer✔1. oxygen
2. respiration/the electron transport chain
3. carbon dioxide
4. citric acid cycle/respiration

The partial pressure of O2 (PO2) is ...... on Mt. Everest than it is at sea level. This is because O2
makes up ...... percentage of the air molecules at high altitudes, but the total number of air
molecules there is ..... at sea level. - Answer✔1. lower
2. the same
3. lower than
Gases move from an area of .... partial pressure to an area of ..... partial pressure . - Answer✔1.
high
2. low
The air in the lungs has .... O2 partial pressure than the outside atmosphere, and ...... O2 partial
pressure than the blood. - Answer✔1. lower
2. higher
Main points of Goose Paper - Answer✔-the geese have adaptation that facilitate flying in high
altitudes
Evaluate:
A. Po2 is lower at the top of Mt. Everest than at sea level
B. Oxygen makes up a smaller percentage of the total air molecules present on Mt. Everest than
it's percentage at sea level.
True or false for each statement, is B a valid explanation of A? - Answer✔- A is true
- B is false
--> oxygen is 1/3 the amount on Mt. Everest than at sea level
how does oxygen move from the lungs to the blood? - Answer✔it moves spontaneously from a
region with a higher concentration of oxygen to a region with a lower concentration of oxygen
How does the Po2 of the outside air compare with the Po2 inside the lungs - Answer✔Po2 is
higher in the outside air
How does the Pco2 of the outside of the air compare with the Pco2 inside the lungs? -
Answer✔Pco2 is higher inside the lungs
proteins are chains of... - Answer✔amino acids
how does carbon dioxide move from the body cells to the lungs? - Answer✔dissolved in blood
plasma
