Question

can someone please tell me what is possible terminology in the blank space?

Osmotic regulation Oceanic distribution There are fishes that can do both like salmon Some fish spend different parts of their lifecycle in different environments. Alevins hatch Changes in environment are made possible by drastic changes in physiology ( plasticity!).

Answer 1

Plasticity = The ability to modify form or physiology to adapt to the changing environmental conditions.

Osmoplasticty = The ability to modify physiology to adapt to the changing salt concentrations

Osmoregulation = The maintenance of a stable osmotic potential in the body irrespective of changes in the environment
