Explanation:

Osmosis is the process by which solvent diffuses through a selective permeable membrane from a low solute concentration zone to a higher one.

In this example, the fish skin represents that selective membrane. Also, we are told that is a marine fish. Sea water have higher concentration of salt and fishes are adapted to it, their cells have also high concentrations of salt compared to freshwater fishes.

If a person placed this marine fish into a fresh water lake, water (solvent) would diffuse down its concentration gradient (from high water concentration in the lake to lower, inside the fish) and therefore enter the fish.
