← Nature & AnimalsWhich disruption occurs when ocean fish excessively drink seawater?
A)Cellular dehydration from osmotic imbalance✓
B)Increased urea production for water balance
C)Decreased salt excretion via gills
D)Reduced active transport by kidney
💡 Explanation
Cellular dehydration results from drinking seawater because the osmoregulation attempts equalization using osmosis rather than active transport of salt alone; therefore the water exits cells to dilute bloodstream salt concentration, rather than just excreting extra salt.
