Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Osmosis is the diffusion of ____ across the cell membrane.
A
Salt
B
Proteins
C
Water
D
Nutrients
Explanation: 

Detailed explanation-1: -Osmosis is the diffusion of water from high concentration to low concentration. When you drink water, your cells have a lower concentration of water than the water in your digestive system. So water flows across the cell membrane (from high concentration to low concentration) of your cells hydrating you.

Detailed explanation-2: -Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Detailed explanation-3: -OSMOSIS. Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.

Detailed explanation-4: -In osmosis, water moves from areas of low concentration of solute to areas of high concentration of solute.
