Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is Osmosis?
A
equal concentration
B
diffusion of water through a selectively-permeable membrane
C
movement of sugar through a membrane
D
non-polar tail
Explanation: 

Detailed explanation-1: -Osmosis is a simple diffusion process. The process of spontaneous net flow of solvent molecules from a selectively permeable membrane into a region of high solute concentration is referred to as osmosis.

Detailed explanation-2: -A selectively-permeable membrane is a membrane that allows only some substances and molecules to pass into or leave the cell. An example of a selectively-permeable membrane is the cell membrane. It allows the passage of only certain types of molecules through diffusion and occasionally by facilitated diffusion.

Detailed explanation-3: -In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane.

Detailed explanation-4: -Osmosis is the passage of water molecules across a semi-permeable membrane from a solution with a high concentration to a solution with a lower concentration. It is a generalized process in which gases also participate.
