comment How long does a signal from the brain take to reach the limbs?
@Christian - Roughly half, I'd assume. A full reflex arc is from a sensory neuron to the spinal column and back out to the muscles. The difference is probably due to length and the added junctions.

comment How long does a signal from the brain take to reach the limbs?
@shigeta - They're some overlap (the Vagus is a good example), but the function maps to the fiber type fairly well since space is the primary limiting factor for the peripheral system. However, I'll admit I haven't refreshed myself of the topic for a while, so it's possible the ratios are less strict than I believe.

comment What is a catalytic domain of an enzyme?
AFAIK MattDMo is correct. The catalytic site is the active site where the reaction takes place that triggers the conformation change. He is also correct about there being nearly infinite potential catalytic site designs.

comment Why do we absorb vitamins better from whole foods than from pills?
@user6035 - Yes, you could eat an artificial diet of macronutrients and micronutrients that would satisfy your biochemical needs. It would probably be "healthy" in that you would probably continue to live without issues you weren't already predisposed to. How other chemicals and compounds contribute to our health are unknown (think antioxidants), but have the potential to contribute significantly. However, please consult medical professionals for further info if you intend to pursue this. Due to genetic variation your body might have greater or lesser needs than the recommendations.

comment How does strength of a pulse related to EKG(ECG)?
Predict? I have no idea. I know V-tach and A-tach can be reasonably predicted by increasingly chaotic signals on an EKG, but I don't think the equipment would have the granularity to predict "strong" and "weak" beats.

comment What is the point of having evolved two nostrils?
I doubt it's so much that two nostrils are that much more beneficial than one as much as that most complex organisms follow bilateral symmetry for their body design. That said, your body will clog one and keep the other clear during fevers, allergies, or when it's cold to prevent it from drying out completely.
