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.

All cell membranes store a small amount of lipids in the form of phospholipids. Phospholipids give cell membranes their structure. Phospholipids consist of a water-soluble head with a tail that repels water, making it hydrophobic.
