Osmosis is the passage of ...1... molecules from a region of their higher concentration to a region of their lower concentration through a ... 2 ... permeable membrane

• 1: sugar, 2: completely

• 1: sugar, 2: partially

• 1: water, 2: completely

• 1: water, 2: partially

The diagram shows two chambers with different concentration of molecules separated by a selectively permeable membrane. Predict what will happen to the water molecules ?

• move from B to A due to diffusion

• move from B to A due to osmosis

• move from B to A due to active transport

• move from A to B due to osmosis
