← Nature & AnimalsWhich outcome occurs when a saltwater fish encounters a sudden freshwater influx in estuarine waters?
A)Extensive cellular lysis due to hypotonicity✓
B)Increased secretion of concentrated urine
C)Enhanced active transport of NaCl into gills
D)Reduced chloride cell activity activation
💡 Explanation
Cellular lysis results because the influx causes significantly lower external osmolality. Osmoregulation (specifically, cellular water balance equilibrium) fails, therefore the excess water influx bursts cells rather than balancing through ion transport under controlled conditions.
