1.The oldest rocks are exposed in the center
1. Diffusion: Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room
2.Osmosis: a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
3. Facilitated diffusion: Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.
4. Protein pumps: a kind of protein that is capable of pumping out compounds that could pose a threat to the cell. An example is AcrB, a bacterial protein complex that repels a wide range of antibiotics through its ability to capture and pump out a spectrum of structurally diverse compounds
5.exocytosis: a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
6.endocytosis: Endocytosis definition and purposes. Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle. These can include things like nutrients to support the cell or pathogens that immune cells engulf and destroy.
