Question

which experiment would you perform to test what happens under extreme exercise conditions?
a) make the mouse run at high speed and/or with low oxygen availability
b) make the mouse run at super speed
c) make the mouse run at high speed with normal oxygen availability
d) make the mouse run at normal speed with normal oxygen availability

Explanation:

Extreme exercise conditions involve both high physical exertion and physiological stress like limited oxygen, which mimics real extreme exercise scenarios. Option a combines high speed (intense exertion) and/or low oxygen (physiological stress), which fully tests extreme exercise effects. Other options lack the combined extreme factors: option b is overly vague, option c only has high speed without oxygen stress, and option d is normal conditions, not extreme.

Answer:

a) Make the mouse run at high speed and/or with low oxygen availability
