Question

a cell placed in an isotonic solution will... a) gain water and burst b) lose water and shrink c) have no net water movement d) gain solutes until equilibrium

Explanation:

In an isotonic solution, the solute concentration is equal inside and outside the cell. Osmosis (water movement) depends on solute concentration gradients. Since there's no gradient, water moves in and out at equal rates, resulting in no net water movement. Option A is for hypotonic (cell gains water), B for hypertonic (cell loses water), and D is incorrect as solute movement (if any) isn't the main factor here, and isotonic means equal solute initially.

Answer:

C) Have no net water movement
