← Nature & AnimalsWhich outcome impairs fish respiration in stagnant water?
A)Reduced concentration gradients across gills✓
B)Elevated water viscosity inhibits flow
C)Damaged gill filaments impede exchange
D)Increased active transport oxygen loading
💡 Explanation
Impaired gas exchange in the gills is caused by lack of fluid motion to maintain the concentration gradients; oxygen transfer via diffusion requires higher oxygen concentrations because, rather than continuous renewal, the stagnant surroundings reach equilibrium.
