comment Are stem cell lines also kept worldwide like HeLa cells?
There is a limit for normal somatic cells - it's called the Hayflick limit which happens due to the fact that the telomeres get shorter with every division and at some point active genetic regions will be shortened. However, this does not apply to stem cells (at least to current knowledge which is pretty solid here) as these cells have an active telomerase.

This is written under the premise that the cell lines are identified by suitable methods and that this identity is controlled regulary.

comment Evolutionary explanation for women having long hair, wearing jewels, stockings and high heel shoes
If this would be evolutionary favorable (as for the colored peacocks) than all individuals should have this. Or if it is a recently acquired trait, all individuals of a certain are should have it. And this is not what I see with make up and related stuff.

There is no evolutionary explanation for this, since this is a social behaviour. Not everything which happens with us can be explained evolutionary.

comment What are the survival limitations of alcohol?
I would say that the main problem with high percentage alcohol is that it is a cytotoxic substance which will not do good.

comment What are the factors on which protein-protein interaction depend?
Proteins are not acidic or basic per se. It depends on the environment - if this is acidic, than some aminoacids can be protonated, while others cannot. But in a given environment proteins are either acidic or basic, but not both.

The answer is relatively simple: About 10% more (assuming that there is not much loss in the uptake and conversion).
