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.

The membrane consists of a double-layer (a phospholipid bilayer) of amphipathic lipids. The hydrophobic ends face each other on the inside, and the hydrophilic ends are on the outsides of the membrane. That way, the hydrophobic regions do not interact with water, and the hydrophilic regions do. Both parts of each phospholipid molecule are happy.. Other molecules are also found in the membrane.
