comment Are there verbs for “undergo mitosis” and “undergo meiosis”?
How about "divide" or even "multiply" (if you include the entire cell cycle)? Those are generic terms, but the process is called cell division. And minor pet peeve of mine: "Google" isn't a verb...

comment Why isn't there any repulsive force between Na+ and K+ disrupting thier roles in transmembrane voltage/ action potentials
I agree with rwst's response below, and just wanted to add that it's not the individual ion species that matter, but the fact that there are several ions, each with ion channels of varying permeabilities. Both sides of the membrane are electrically neutral, but the chemical potentials differ due to the channels. More specifically, the resting membrane potential exists because of the higher permeability of the K+ channels.

comment Is there a biological basis to physical attraction?
@shigeta I agree, and I didn't mean it to sound like attraction was completely biological, just that there is some biological part of it. The examples I chose (or at least the first and last ones) were intended to highlight interesting and bizarre findings that caught my attention. I wrote it at work, so I probably didn't do a good job of writing it up...

I didn't take it that way, no worries :)

comment Does body mass have a bearing on reflex speed?
That's really interesting, thanks. I didn't realize there would be such measurable changes, even in the larger nerves. Diabetic neuropathy causes serious problems for people, initially in the hands and feet, due to their distance from the brain. But apparently excess weight can cause negative physiological changes to nerves.

comment Do egg laying animals experience a pregnancy?
And can you also clarify what "pregnancy-like period" refers to? A "period" can refer to two things :P And the short answer is yes, but I don't fully understand the question.

comment How is hibernation/aestivation different from anesthesia?
I'm assuming you're referring to general anesthesia, which still encompasses many types of mechanisms. Here's an interesting article about whether humans can hibernate. It's not a true scientific paper, but it brings up some interesting points.

comment What controls the feeling of discomfort/comfort before and after sleep?
The compound you're thinking about is lactic acid. When oxygen is low, pyruvate is reduced to lactic acid to regenerate NAD+. It might have something to do with the aching related to sleep, but I'm not sure.
