Answer:
a. Nothing happens because the two solutions are isotonic to one another.
Explanation:
Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.

Alfred Wegener has spent lot of times looking at maps, as it was his job. One day he noticed something peculiar, the western coast of Africa and the eastern coast of South America were an almost perfect match. They looked like peaces of puzzle that belong together.
