← Nature & AnimalsWhich biological process determines shark tissue salt concentration?
A)Urea-based osmoregulation retention mechanism✓
B)Dietary electrolyte intake regulation
C)Active chloride cell secretion process
D)Metabolic water conservation strategy
💡 Explanation
Sharks use urea-based osmoregulation retention because it allows their internal salt concentration to be slightly higher than seawater; therefore water passively enters their bodies, rather than being constantly lost to the salty environment.
