For Question 9, the correct answer would be dynamic equilibrium. In an isotonic solution, the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell, resulting in no net movement of water across the cell membrane. The water molecules move in and out of the cell at equal rates, leading to a state of dynamic equilibrium.
For Question 10, it seems the question may be incomplete. If you provide the entire question or specify what you need to know, I’d be happy to assist!
