Question

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

Explanation:

Osmosis is the process where water molecules diffuse 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 is a general term for transport that doesn't require energy and includes diffusion of various substances, not just water. Dynamic equilibrium is a state where there is no net change, but it's not the specific term for water - only diffusion.

Answer:

B. osmosis
