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? Salbcted Answerss higher one orlo bood Po2 b higher ventlatory 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 (Increased diffusion. See Fick Equation.) e. higher hemoglobin affinity that is especially temperature sensitive a, higher toleranceor 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 (Increased diffusion. See Fick Equation.) d an inactive lifestyle that reduces O2 demand e. higher hemoglobin affinity that is especially temperature sensitive f. mitochondria in muscles are closer to the capillaries than usual. g more efficient muscles that need less oxygen and ATP Answers: a mutation in their hemoglobin destabilizes the T state, which increases oxygen affinity

Explanation / Answer

1. Selected answers:

b) Higher ventilatory response to hypoxia.

a) Higher tolerance for low blood PO2.

c) Increased lung size relative to body size for a bird.

e) Higher hemoglobin affinity that is especially temperature sensitive.

2. Selected answers:

c) The Zmb max increases as Zmb increases.
