Vedclass · Answer

(A) When a marine fish is placed in fresh water,the concentration of solutes in the surrounding fresh water is much lower than the concentration of solutes in the fish's body fluids (cytoplasm). Due to this concentration gradient,water molecules move from the surrounding environment into the fish's cells through the process of endosmosis. This influx of water causes the cells to swell and eventually burst,leading to the death of the fish.
