Question

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

Explanation:

Osmosis is specifically the diffusion of water molecules across a semi - permeable membrane from an area of high water concentration to an area of low water concentration. Passive transport includes other types of molecule diffusion besides water. Active transport requires energy and is not related to simple water - only diffusion. Dynamic equilibrium is a state, not a transport process.

Answer:

osmosis
