Question

The diagram shows two solutions of strong glucose and weak glucose solution, which are separated by a partially permeable membrane. This membrane will allow the transfer of water molecules not glucose molecules. As a result?

Choices

Choice (4) Response
a.

No change will occur in both solutions

b.

Water can move from the left to right

c.

From left to right against their concentration gradient

d.

Water can move from the right to the left

Answer

d.

Explanation

The diagram shows two glucose solutions of strong glucose and weak glucose solution, which are separated by a partially permeable membrane. This membrane will allow the transfer of water molecules not glucose molecules. As a result water can move from the right, where there is high concentration of water molecules is present, to the left, where water concentration is low.
