Detailed explanation-1: -Correct option (B) Explanation of the correct option (B): Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. It is the net movement of molecules or atoms from a region of high concentration to a region of low concentration.
Detailed explanation-2: -The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration.
Detailed explanation-3: -Diffusion is defined as the net movement of molecules from an area of greater concentration to an area of lesser concentration. The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy.
Detailed explanation-4: -Passive transport does not require energy input. An example of passive transport is diffusion, the movement of molecules from an area of high concentration to an area of low concentration. Carrier proteins and channel proteins are involved in facilitated diffusion.
