Answer :
The Correct answer is d) Diffusion involves the movement of molecules into or out of a cell.
What is Diffusion?
- The process of molecule movement along a concentration gradient is called diffusion. When molecules travel from one area with a higher concentration to one with a lower concentration, it happens. Every living creature experiences it, and it is a significant process.
- The movement of materials into and out of cells is facilitated by diffusion. The molecules move from an area of higher concentration to an area of lower concentration until the concentration is the same everywhere.
- Since molecules can move about in gases and liquids, diffusion takes place in such media.
- Diffusion is frequently employed throughout several academic fields, including physics, chemistry, and biology. The two primary types of diffusion are simple diffusion and assisted diffusion.
