Question

8. A pronghorn can run for a longer period of time than a cheetah because a pronghorn a. is adapted to aerobic respiration during running while the cheetah relies on anaerobic cellular respiration. b. achieves faster speeds than the cheetah does c. has stronger sprinting skeletal muscles than the cheetah does. d. more glycogen in its muscles than the cheetah does 9. When looking at the ratio of Vozmax to resting Oz consumption at the same temperature, we are referring a. symmorphosis b. aerobic scope of activity. c. aerobic expansibility. d. aerobic capacity.

Answer 1

Answer : 8 ) a

Pronghorn opens its mouth while running to intake more oxygen while cheetah relies on anaerobic respiration which releases energy faster than aerobic respiration by breaking down glucose molecules without oxygen. aerobic capacity allows proghorn to run for a longer period of time than cheetah. All other options are wrong.

9) c

definition of aerobic expansibility is the ratio of VO2 max to resting O2 consumption at a particular temperature.
