D)sugars and salts moving down their concentration gradient

Question

Quizplus · Accepted Answer

Osmosis involves the movement of water molecules from an area of high concentration to an area of low concentration, which is also known as a concentration gradient. This is the process by which water molecules move through a selectively permeable membrane. Therefore, the correct answer is option A.
