When Salinity Increases, Many Invertebrates React By

Question

When salinity increases, many invertebrates react by
A) Rapidly taking up inorganic salts
B) Degrading amino acids, to produce cellular ammonia
C) Synthesizing urea
D) Synthesizing free amino acids

Accepted Answer

When salinity increases, many invertebrates synthesize free amino acids to help balance the osmotic pressure, allowing them to better cope with the increased external salinity. This process helps to maintain their internal water balance by adjusting the osmotic pressure inside their cells.
