← Nature & AnimalsWhich outcome occurs when a fish's operculum collapses, impeding efficient gas exchange?
A)Reduced oxygen uptake in gills✓
B)Increased carbon dioxide elimination
C)Enhanced diffusion across capillaries
D)Elevated metabolic waste removal
💡 Explanation
Reduced oxygen uptake occurs, because opercular pumping drives water across gills, which facilitates countercurrent exchange. Therefore, inhibited pumping prevents effective oxygen diffusion into the bloodstream, rather than enhancing gas exchange or directly affecting waste removal.
