Question

multiple choice question osmosis is the passive movement of ______ through a selectively permeable membrane. ions solutes water

Explanation:

Osmosis is defined as the passive movement of water molecules across a selectively permeable membrane from a region of lower solute concentration (higher water potential) to a region of higher solute concentration (lower water potential). Ions and solutes generally move via processes like active transport or facilitated diffusion, not osmosis. So the correct option is water.

Answer:

C. water (assuming the options are labeled as A. ions, B. solutes, C. water)
