How Cell Membrane Lets Things in and Out?

It is the cell membrane that keeps the insides in and the outside out. Though like your house it has doors and windows in it to let things in and out. A cell membrane is very flexible and the cell can change shape quite easily. However some cells have given up this flexibility for greater strength and protection in the form of a ‘cell wall’. A cell wall is not flexible so cells that have one have a constant shape.

How Did Aids Come About?

Back in the late 90’s, there was a study that showed that the oldest know HIV specimen was a virus that did in fact transfer from an animal to a human. This may have happened as early as the 1940’s. In 1959, a man that looked healthy went to give blood for a study devoted to blood disorders. The blood was analyzed, frozen, and then completely forgotten about. In the 80’s, researchers observed the blood a second time and found that there was a strain of HIV in it. This is the oldest known specimen that has been taken of the AID’s virus and it is theorized that it will help scientists realize when and how it really transferred from the monkey/chimpanzee to the human.
