Re: How would I do this experiment? [Advanced]

Have you planned how shall you count E. coli cells and Kefir cells and distinguish between them? If you use turbidity as a measure of concentration of bacteria, it may not distinguish between those two, moreover you may get noise due to killed/dead cells in the readings. If you use live cell stains,...

Re: Can human body hair disappear as a result of... clothing?

In this case, in addition to natural selection, sexual selection must also be operating: different sexes may show particular mating preference for other sex's characteristics. If females prefer hairy males and males prefer hairless females, the forces would be conflicting. As you have pointed out, t...

Re: Oxygen requirements of eukaryotes

Here is a user's guide for parasites, may have some of your organisms with their oxygen requirement:,

Also, I know of Bergey's manual for bacterial taxonomy, you could check if something similar exists for all of the eukaryotic microbes.

Re: Purpose of a primase/polymerase localized to the cytosol?

Hi, I have some naïve thoughts about this situation: If it is an RNA pol, it may be helping maintain/regulate RNA levels in cytosol by e.g. recharging decaying RNA levels in cytosols for extended translation. If it is a DNA pol, it might be a long surviving vestigial remnant of bacterial ancestry. I...

I don't have an expertise in this area, but have some guesses to offer. I see that it is a possibility that such useless or harmful instincts prevail for some time, but it is also likely that such instincts may undergo mutation ( mutation in its broader sense) and selection to establish useful repla...
