Which outcome occurs when high metabolic demand affects a fish in oxygen-poor water?

💡 Explanation

Increased metabolic demand forces enhanced oxygen uptake driven via lamellar recruitment; blood flow reroutes to maximize countercurrent exchange because fish expand active gill surface area rather than reduce effort, and maintain function to limit buildup rather than decrease functions overall.
