Question

part a during osmosis, ____ move(s) across the membrane. options: solute, solution, ions, solvent.

Explanation:

Osmosis is the process by which solvent molecules (usually water) move across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Solute molecules generally do not move freely across the membrane in osmosis (they may be restricted by the semi - permeable nature of the membrane), ions are a type of solute in many cases, and a solution is a mixture of solute and solvent, so it is the solvent that moves during osmosis.

Answer:

solvent
