← Nature & AnimalsWhich physiological consequence occurs when marine vertebrate osmoregulation fails?
A)Cellular dehydration by osmotic water loss✓
B)Buildup toxins like NH3 and urea
C)Catastrophic failure energy regulation cells
D)Impairs efficient oxygen transportation tissues
💡 Explanation
Osmoregulation prevents excess ion concentrations in cells; loss causes cellular *desiccation* because water passively exits cells along the concentration gradient resulting in cellular shrinkage and organ failure, therefore dehydration occurs rather than toxin buildup or failure of O2 transport.
