....i dont even know how to nswer this one becasue i dont know wht and isotonic solution means

Answer 1

An isotonic solution is a solution in which concentration or solute is equal to that of a cell placed in it. Thus, the system is in dynamic equilibrium, and so water molecules flow in both directions.
The correct answer is C. water molecules flow in both directions at the same rate.
