Organs of salmon work to control homeostasis but endocrine and nervous system engage more in maintain homeostasis.
Answer:

aquaporins are channel proteins that allow water to flow through a membrane. The rate of osmosis depends on ratio of intracellular to extracellular concentration as well as the presence of aquaporins in the cell membrane
Because they have different functions (so different genes are active in different tissues)
