Compare and contrast osmosis and diffusion?
Diffision is the net movement of molecules from an area where there are many to an area where there are few. Osmosis is the diffusion of water through a cell membrane. Both use each other because diffision is what happens in an osmosis.
How do liver cells work?
They work well unless you drink alcohol. Basically a liver cell filters out substances taht can be harmful to the body, but alcohol and a number of other less popular substances severely damage the abilities of the liver cells over time. All i really know about liver cells is that there also called hepatocytes. LFTs or liver function tests can be used to assess the functioning of the liver cells. I guess that they receive oxygen via diffision.
What are the functions of alveoli?
Alveoli are tiny sacs in the lungs that perform gas exchange. That is the main process of respiration where the body gets rid of carbon dioxide and picks up oxygen which is used in metabolism. They have supply of oxygenated and de-oxygenated blood surrounding their surface giving them a high blood supply. They also have thin walls and a moist surface. This is all required for them to work correctly.

In 1849, a delegation of the National Assembly met in Berlin and offered King Fredrick William IV the crown of Emperor over Germany, he told them he wanted a vote in.
Explain Fick's First Law of Diffusion?
Fick's First Law of Diffusion deals with diffusive flux. The law postulates that flux goes from high to low areas of concentration with a magnitude that is proportionate to its spatial derivative.
