Hello!

❖ This is known as active transport. Active transport uses the cell's energy to move molecules from an area of high concentration to an area of low concentration.
(Note: Active transport is the only time that molecules move from high to low concentration)

<span>Mutagens are chemical or physical factors that increase the rate of mutation.</span>
We do science because if we didn't we would not know a lot of the things we do know now.
The answer is B, osmosis is the movement of water. Diffusion is the movement to chemicals and molecules.
Both osmosis and diffusion are movement of molecules from a region of higher concentration of the substance moving to lower concentration down the concentration gradient. However, osmosis is only for the movement of water molecules, while diffusion is for any type of substances including liquid or gas. So we can also say osmosis is a type of diffusion actually.
And also, both of these movement of molecules does not require extra energy, they all happen due to natural tendency.
