• water * sugar

semipemeable membrane (with arrow pointing to the membrane between two beaker sections labeled a (left) and b (right))
the beaker shows a membrane that is only permeable to water but not sugar. side dropdown is hypertonic since it has a higher concentration of dropdown.
i predict that the level of water on side dropdown will go up.

Explanation:

Step1: Identify hypertonic side

A hypertonic solution has a higher solute (sugar) concentration. Side B has more sugar (red dots) than side A. So side B is hypertonic.

Step2: Predict water movement

Water moves from low solute (high water) to high solute (low water) via osmosis. Since B is hypertonic (more sugar), water moves to B, so water level on B will rise.

Answer:

First blank: B; Second blank: B; Third blank: sugar
