Question

the membrane does not allow the green molecules to pass through it. what will happen next? water will flow into side a. water will stay still. water will flow into side b.

Explanation:

This is a question about osmosis. Osmosis is the diffusion of water across a semi - permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Since the membrane doesn't allow the green molecules to pass, water will move to equalize the solute concentration. Side B has a higher solute concentration (more green molecules), so water will flow into side B.

Answer:

Water will flow into side B.
