Question 10 Answer a. equal on both sides of the membrane b. concentration of solutes in the environment is low with respect to the cytosol of the cell c. will never be equal on both sides of the membrane d. concentration of solutes in the environment is high with respect to the cytosol of the cell

Answer 1

Answer: A. Equal on both sides of the membrane.

Explanation: Here, we are discussing types of solutions. In an isotonic solution, concentrations of water are equal on both sides of the membrane. This is opposed to that of a hypertonic solution (where concentrations of water are higher outside of the membrane, leading to shrinkage) and a hypotonic solution (where water is concentrated inside the membrane, leading to swelling.
