← Nature & AnimalsWhich risk increases for deep-sea fish when tissues exceed protein denaturation temperature?
A)Loss of buoyancy control during swim✓
B)Increased bacterial symbiotic activity rate
C)Enhanced bioluminescence signal production
D)Accelerated osmoregulation pump ATP hydrolysis
💡 Explanation
Buoyancy changes quickly with temperature, because protein denaturation alters swim bladder gas permeability reducing the fish's control; therefore, regulated ascent fails, rather than other metabolic or symbioses because the swim bladder's regulation relies upon intact and working proteins.
