Question

study the illustration. the small blue spheres represent water molecules.
in which direction will water molecules move across the membrane?
there will be no net movement of water.
water will move from a to b.
water will move from b to a.

Explanation:

Water moves by osmosis from an area of higher water concentration to lower. Side A has fewer solute particles (implied by fewer dots) than Side B, so water concentration is higher in A. Thus, water moves from A to B.

Answer:

Water will move from A to B.
