Question

multiple choice question
what process, that occurs in capillaries, is described as the movement of molecules across a membrane under the influence of hydrostatic pressure?
osmosis
diffusion
active transport
filtration

Explanation:

Osmosis is the movement of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Active transport requires energy to move molecules against a concentration gradient. Filtration is the movement of molecules across a membrane under the influence of hydrostatic pressure, which is consistent with the description in the question.

Answer:

D. Filtration
