PPM (parts per million)- a 100 ppm solution is 0.01%. The "parts per" notation, while still in use, has largely been replaced by mole fraction PPB (parts per billion)- typically used to express contamination of dilute solutions Some units may be converted from one to another. However, i...

In biology, this is a difference between the two processes. One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane. This can be confusing because ...

Given baseline levels of (on average) 0.14ppm in women and 0.18ppm in men, this works out to a 1.96-3.42 ppm increase. More than twice what Enovid manages. The dominant model is that the new NO in the nose is borrowed from the sinuses rather than being newly generated. Even if this ...
