← Nature & AnimalsWhich impairment affects marine fish when epithelial chloride cells' exchange capacity saturates at highly elevated salinity?
A)Osmotic imbalance initiates cellular dehydration✓
B)Oxygen uptake decreases causing systemic hypoxia
C)Buoyancy control collapses in swim bladder
D)Digestive enzyme malfunctions cause starvation
💡 Explanation
When exchange capacity is saturated, osmotic disregulation inhibits salt excretion, resulting in lower water potential and cellular dehydration because water diffuses down the gradient to equalize the relative concentrations. Osmotic imbalance triggers cellular dehydration, rather than hypoxia, buoyancy loss or, digestive malfunction because those relate to separate physiological processes.
