Sure, let's address the question about the net movement of water between a 10% and 20% sucrose solution separated by a membrane impermeable to sucrose.

Answer
The net movement of water will occur from the 10% sucrose solution to the 20% sucrose solution.
Solution
a
Osmosis: Osmosis is the movement of water molecules through a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration
b
Concentration Gradient: In this scenario, the 10% sucrose solution has a lower concentration of solute compared to the 20% sucrose solution
c
Direction of Water Movement: Since the membrane is impermeable to sucrose, water will move from the 10% sucrose solution (lower solute concentration) to the 20% sucrose solution (higher solute concentration) to balance the solute concentrations on both sides of the membrane
Key Concept
Osmosis
Explanation
Osmosis is the process by which water moves across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, water will move from the 10% sucrose solution to the 20% sucrose solution.
