4. A beaker with a membrane is separating two solutions, initially of equal volumes. The solution on side A is 100 mM KCl while the solution on side B is 150 mM sucrose. The membrane is not permeable to ions or carbohydrates. In what way will the water move? (A) down its concentration gradient from side B to side A (B) down its concentration gradient from side A to side B (C) In osmosis, water moves against its concentration gradient. (D) As sucrose dissociates, it creates more individual molecules in solution and is therefore the higher concentration gradient. (E) There is no movement of water.
