Which constraint on bar-headed geese increases when flying over the Himalayas?

💡 Explanation

Reduced partial pressure of oxygen at high altitudes limits its diffusion across membranes because, at a lower concentration gradient, Fick's Law of Diffusion dictates reduced rate of transport; therefore, oxygen diffusion decreases because there is less driving force, rather than changes capillaries or temperature factors.
