The lipid bilayer is a thin polar membrane made of two layers of lipid molecules.These membranes are flat sheets that form a continuous barrier around all cells.The cell membranes of almost all living organisms and many viruses are made of a lipid bilayer, as are the membranes surrounding the cell nucleus and other sub-cellular structures.rokaryotes have only one lipid bilayer-the cell membrane (also known as the plasma membrane). Many prokaryotes also have a cell wall, but the cell wall is composed of proteins or long chain carbohydrates, not lipids.
Cholera is an infection of the small intestine that causes a large amount of watery diarrhea. Cholera is caused by the bacterium Vibrio cholerae. These bacteria release a toxin that causes an increased amount of water to be released from cells that line the intestines. This increase in water produces severe diarrhea. People get the infection from eating or drinking food or water that contains the cholera germ. Living in or traveling to areas where cholera is present raises the risk of getting it. Cholera occurs in places with a lack of water treatment or sewage treatment, or crowding, war, and famine.
