D. Predict the direction of net flow of water across a cell membrane due to osmosis given information about solute concentrations on either side of the membrane. Explain what happens to rates of movement of water molecules in both directions across the membrane at equilibrium.

The net movement of water across the membrane is zero.

Explanation:

For a cell membrane that is at equilibrium, the rate of movement of water molecules in both directions is equal. That is, there is no net movement of water molecules across a cell membrane that is in equilibrium. An equal amount of water molecules travel in and out of the cell
