Question

osmosis across a cell membrane can be modeled using a u - shaped tube. this diagram of a u - shaped tube shows two solutions immediately after they were poured into the tube. the solutions were made by dissolving different amounts of the same solute in water. according to the diagram, which statements describe the solutions immediately after they were poured into the u - shaped tube? select all that apply. the two solutions have different concentrations. the two solutions are at equilibrium. the two solutions have the same volume. water is the solute in both solutions.

Explanation:

• The diagram shows different amounts of solute in water on each side, so concentrations are different.
• Equilibrium is not reached as there is a concentration - gradient.
• The liquid levels in the U - tube are the same initially, indicating equal volumes.
• Water is the solvent, not the solute.

Answer:

The two solutions have different concentrations.
The two solutions have the same volume.
