Diffusion-movement of substances from a region of higher concentration to a region of lower concentration down a concentration gradient.
Osmosis (also similar to diffusion) - movement of water molecules from a region of higher water potential to a region of lower water potential down a water potential gradient:)
Random thermal motion causes molecules to move around, without requiring any specific method of moving them. If there is more of some compound on one side of a membrane than there is on the other side, there will be what is known as osmotic pressure. Sheer random motion will tend to equalize such differences in concentration.
Diffusion is what leaves the cells. The cells has to have cellular energy.
Cellular Respiration
They all need to repodes
Respiration by definition refers to oxygen exchange. However cellular metabolism which does not require oxygen is called glycolysis.
If you are looking for a cellular phone directory, your best bet would be the National Cellular Directory. This is an opt in service, so they might not have the number you require.
Only one, passive diffusion.
Diffusion is the methods that leave cells. Diffusion also has to have cellular energy.
Both of these methods require the presense of matter.Both of these methods require the presense of matter.Both of these methods require the presense of matter.Both of these methods require the presense of matter.
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
