Answer:
Your answer is below
Explanation:
The first picture shows a cell membrane inside the protein there is a protein that needs energy to carries a molecule. Then, picture a is active transport, it needs energy.
The second picture shows a cell membrane that is that is eating a molecule then this picture shows a endocytosis process. It needs energy.
The third picture shows a cell membrane and a protein inside it, but it doesn't needs energy to carries a molecule, then this picture is an example of facilitated diffusion.
The fourth picture shows a membrane that is excreting wastes or molecules, then this picture is exocytosis. It needs energy.
