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. complete the sentence. the solution on the left side of the membrane has a ____ concentration of solute and a ____ concentration of water than the solution on the right side of the membrane. higher...higher lower...higher lower...lower higher...lower

Explanation:

To determine the solute and water concentrations, we analyze the number of solute molecules (orange dots) on each side of the semipermeable membrane. The left side has fewer solute molecules than the right side, so it has a lower solute concentration. Since the total volume of the solution (water + solute) is considered, a lower solute concentration means a higher water concentration (because water molecules are more abundant relative to solute on the left). Thus, the left - side solution has a lower solute concentration and a higher water concentration compared to the right - side solution.

Answer:

B. lower...higher
