QUESTION (Select all that are correct.) Which of the following are ways that bar-headed geese are adapted to the low-oxygen environment at which they migrate? O a. higher tolerance for low blood PO2 b.higher ventilatory response to hypoxia (They increase their depth of breathing more than other birds when blood PO2 is low.) C.increased lung size relative to body size for a bird (ncreased diffusion. See Fick Equation.) d an inactive lifestyle that reduces 02 demand e. higher hemoglobin affinity that is especially temperature sensitive O f. mitochondria in muscles are closer to the capillaries than usual. 9 more efficient muscles that need less oxygen and ATP h. a mutation in their hemoglobin destabilizes the T state, which increases oxygen affinity.

Explanation / Answer

1. The option a, b, c, and e are correct.

a. Higher tolerance for low blood PO 2.
b. Higher ventilatory response to hypoxia.
c. Increased lung size relative to body size for a bird.
e. Higher hemoglobin affinity that is especially temperature sensitive
2. the Option c and e are correct.

c. the Z mb max increases as zmb increases.
e. The zmb max increases then decreases again as zmb increases.
