The mechanism of regulation, generally between organism and its environment, of solutes and the gain and the loss of water is called________?

Explanation

Osmoregulation is the control of water balance and the concentration of dissolved salts in an organism relative to its environment. It maintains suitable water potential and ion concentration in body fluids. Students may choose homeostasis, but homeostasis is the broader maintenance of a stable internal environment, whereas osmoregulation specifically concerns water and solutes.
