Question

complete the paragraph to describe what happens during osmosis.
during osmosis, there is a net movement of water molecules across a membrane toward the area of higher solute concentration. the movement of water molecules into that area dropdown the solutions volume on that side of the membrane, which consequently options: increases, decreases the solutions concentration on that side.

Explanation:

During osmosis, water moves to the area of higher solute concentration. When water molecules move into that area, the amount of liquid (solution's volume) on that side of the membrane increases. This increase in volume, with the solute amount remaining relatively constant (assuming no solute movement), will lead to a decrease in the solution's concentration (but the question here is about the volume change, so the correct word for the volume change is "increases").

Answer:

increases
