Question

which homeostatic process is characterized by the diffusion of only water molecules?
active transport
osmosis
passive transport
dynamic equilibrium

Explanation:

Osmosis is the diffusion of water molecules across a semi - permeable membrane from an area of higher water concentration to an area of lower water concentration. Passive transport includes diffusion and osmosis but osmosis specifically refers to water diffusion. Active transport requires energy and moves substances against a concentration gradient. Dynamic equilibrium is a state of balance.

Answer:

osmosis
