<span>The answer is C)Water molecules flow in both directions at the same rate. In a hypotonic solution, the water concentration of the cell's cytoplasm is lower than that of the hypotonic solution. In a hypertonic solution, the water concentration of the cell's cytoplasm is higher than that of the hypotonic solution. In, an isotonic solution, there is a balance in the water concentration between the cell's cytoplasm and the solution. Thus, water molecules flow in both directions at the same rate.</span>
