Which outcome occurs when amphibian tadpoles develop in oxygen-depleted water bodies?

💡 Explanation

When tadpoles are in oxygen-depleted water, increased respiratory demand activates hypoxia-inducible factors, stimulating angiogenesis and cell proliferation in the gills, expanding their surface area for enhanced oxygen diffusion. Therefore, branchial surface area increases, rather than other adaptations that alter blood properties, development speed or cutaneous oxygen uptake, as gill perfusion is immediately modified in response to the oxygen changes
