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. Active transport requires energy and moves substances against a concentration gradient. Passive transport includes diffusion of substances other than just water. Dynamic equilibrium is a state where there is no net change, not specifically the diffusion of water.

Answer:

B. osmosis
