DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mrs. Crandall placed 2 tablespoons of salt into a glass of water and then placed a selectively-permeable membrane into the glass that divided the glass into left and right halves. The left side is ____ to the right side.
A
isotonic
B
hypertonic
C
hypotonic
Explanation: 

Detailed explanation-1: -osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances-i.e., solutes).

Detailed explanation-2: -The diffusion of water across a selectively permeable membrane is called: B. osmosis. Osmosis is a transport pathway that allows the movement of water molecules down the concentration gradient across the plasma membrane in most living organisms. The process occurs passively without the need to expend ATP energy.

Detailed explanation-3: -The diffusion of water molecules through a selectively permeable membrane is known as osmosis.

Detailed explanation-4: -Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes.
