(3 points) Simple diffusion- moves molecules from an field of battle of higher concentration to an firmament of lower concentration without an input of energy. Facilitated diffusion- follows the same rules as however diffusion (higher to lower concentration and no energy input), kick upstairs uses protein carrier molecules to allow substances that are fa t soluble to balmy through the cell membra! ne. 5. List three examples of passive transport mechanisms. (3 points) Diffusion Facilitated Diffusion Osmosis 6. How can the concentration of water in a consequence be lightd? (3 points) You could also use what is fundamentally dialysis to decrease the water concentration, placing your solution inside a dialysis saucer with holes size to be permeable to water.
