Final answer:
Osmosis will cause water to move from side A (hypotonic) to side B (hypertonic) until there is an equal water concentration on both sides, reaching isotonic equilibrium.
Step-by-step explanation:
When water is added to one side of a membrane (side A), and an equal volume of a 5% solution of glucose is added to the other (side B), a process called osmosis occurs. This means that water molecules will move from side A, which is the hypotonic solution with a higher concentration of water, to side B, the hypertonic solution with a lower concentration of water. The movement of water will continue until the concentration of water is equal on both sides, reaching a state called isotonic equilibrium.
During this process, the water level on side A will decrease, while the level on side B will increase until the osmotic pressure is balanced. This is because the glucose molecules cannot move across the membrane, but the water can. Therefore, the water moves to where there are fewer water molecules (side B), which also has a higher concentration of glucose, until equilibrium is reached.
