I hadn't seen tenor either. I checked in Google and there are 17,700 examples of tenure and only 959 of tenor, so I think it could be a mistake. If you look at these two examples from the same bank, it does look like a mistake: http://www.icicibank.com/pfsuser/loa...howtorepay.htm. http://icicibank.com.sg/sg_loanagainstdep.htm.
Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients. Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane.The simple diffusion of water is known as osmosis.onpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.

Phospholipids serve a major function in the cells of all organisms: they form the phospholipid membranes that surround the cell and intracellular organelles such as the mitochondria. The cell membrane is a fluid, semi-permeable bilayer that separates the cell's contents from the environment, see animation below.ipid molecules are slightly soluble to insoluble in water. Lipids are hydrophobic because the molecules consist of long, 16-18 carbon, hydrocarbon backbones with only a small amount of oxygen containing groups. Lipids serve many functions in organisms.
