Question

Quizplus · Accepted Answer

When a freshwater animal is transferred to seawater, it needs to adapt to the higher salinity. This adaptation involves increased aquaporin expression in the intestinal epithelia to facilitate water absorption and increased NKCC (Na-K-Cl cotransporter) expression in the gill lamellae to excrete excess salts.
