Question

which of the following molecules crosses through a semipermeable membrane during the process of osmosis? salt water protein sugar

Explanation:

Osmosis is the movement of solvent molecules (usually water) across a semipermeable membrane from a region of lower solute concentration to higher solute concentration. Salt, protein, and sugar are solutes and generally do not pass through the semipermeable membrane during osmosis; water (the solvent) does.

Answer:

water
