Question

which of the following statements about the conditions shown in the u - shaped tube are true? select all that apply. water is tightly clustered around the hydrophilic solute molecules on both sides of the membrane. there is less free water in the right arm of the tube than in the left arm of the tube. solutes can pass through the selectively permeable membrane from right to left, but free water cannot. there is more solute in the left arm of the tube than in the right arm of the tube.

Explanation:

• Water molecules cluster around hydrophilic solutes due to their polar - nature. In the right arm with higher solute concentration, more water is associated with solutes, leaving less free water compared to the left arm. Solutes cannot pass through the selectively - permeable membrane as they are too large, while water can move by osmosis. The right arm has more solute.

Answer:

Water is tightly clustered around the hydrophilic solute molecules on both sides of the membrane.
There is less free water in the right arm of the tube than in the left arm of the tube.
