Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes
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.
