Question

Two solutions are separated by a semipermeable membrane with the same properties as a cell membrane. Solution A is 5% glucose and solution B is 10% glucose. Under these circumstances...

a) Water will move from Solution B to Solution A.
b) Water will move from Solution A to Solution B.
c) There will be no movement of water.
d) Glucose will move from Solution B to Solution A.

Answer 1

Water will move from the hypotonic solution (Solution A) to the hypertonic solution (Solution B) through osmosis until equilibrium is reached.

Step-by-step explanation:

When two solutions with different glucose concentrations are separated by a semipermeable membrane, which allows water but not glucose to pass through, osmosis occurs. Osmosis is the movement of water across a semipermeable membrane from an area of higher water concentration (or lower solute concentration) to an area of lower water concentration (or higher solute concentration).

In this case, Solution A is a hypotonic solution with 5% glucose, and Solution B is a hypertonic solution with 10% glucose. Since water moves from the hypotonic to the hypertonic solution, the answer is: b) Water will move from Solution A to Solution B until equilibrium is achieved, meaning both solutions will reach an isotonic state with equal concentrations of water and solute on both sides of the membrane.
