Question

two solutions are separated by a selectively permeable membrane. if solution a has a higher concentration of a nonpermeating solute than solution b, then
multiple choice
neither the solute nor water will diffuse
water will pass down its concentration gradient from solution b to a
the solute will pass down its concentration gradient from solution b to a
water will pass down its concentration gradient from solution a to b
the solute will pass down its concentration gradient from solution a to b

Explanation:

The solute is non - permeating, so only water can diffuse. Water moves from an area of higher water concentration (lower solute concentration, solution B) to an area of lower water concentration (higher solute concentration, solution A) down its concentration gradient.

Answer:

water will pass down its concentration gradient from solution B to A
