That clicking thing was a Geiger counter. If it's clicking alot, there's alot of radiation. Doesn't matter what type (a/b particle emissions, radon is a).
Well they call it tricarboxylic acid cycle in my cell and molec book. I guess it's just how it works in upper level biology classes, something which you're not yet familiar with.
Bah. Everyone knows that glycolysis just produces pyruvate for the tricarboxylic acid cycle, so I might have included that, which takes place in the mitochondria (only in eukaryotes).
An 80 year doesn't have any knowledge that would help a 30 year old reproduce, at least not any that other 30 year olds don't have. Also, consider that language only came along 200,000 years ago by a random mutation, so obviously before that there were no elderly by our standards today, and certainly no way to communicate high level knowledge.
Anything more than basic knowledge is not a survival factor. In fact, the cretins breed more... so being ignorant is more of an advantage than being a genius. Knowledge needed to survive can be imparted by just about anyone.
What is everyones opinion on which level of physics you should take? College Physics is algebra based and alot simpler, University Physics is calculus based and alot harder, but gives you a better understanding. Obviously if you're a physics major you should take calc based, but what about if you're in another major?
Amino acids form RNA... and there's strong evidence RNA might have been able to self-replicate in the past. Translation now involves enzymes that bind to RNA... but there are some cases where other parts of the RNA chain itself acts as the enzyme. These could be remnants of how it used to work.
