Moving molecules from low to high
Kay [80]

Answer:

Active transport

Explanation:

Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.
