comment What does the human body use oxygen for besides the final electron acceptor in the electron transport chain?
@WYSIWYG You seem to know more about this than I do clearly. So far I had no reason to doubt the text books in this regard. I’ll happily defer to your expertise.

@WYSIWYG Your analysis is better. I didn’t actually want to get too hung up on the $\ce{O2->CO2}$ conversion (that was by accident), I just wanted to show that the stuff we breathe in is used up in respiration. Maybe I’ll clarify that and reference your answer.

comment Genes-of-interest analysis between organisms
@AliceD RNA-seq is a gene expression profiling technique akin to microarrays. The sequencing step is just a technical detail.

comment Why cancer is not a communicable disease?
@Kendall I have to admit that I don’t know anything about that, but please feel free to add your own answer and/or edit mine. Also, thanks for this interesting piece information, I didn’t know that.

comment Why cancer is not a communicable disease?
@GoodGravy No, it’s not a moot point at all, because it doesn’t explain why cancers generally aren’t transmissible, and that was the whole question. (I also disagree with your edit, since it changed the answer substantially, and such edits are frowned upon on Stack Exchange – you should have written your own answer instead.)

comment How do I find a protein from this DNA sequence?
Translation would fail on this sequence since it’s not a complete open reading frame (doesn’t start with a start codon, doesn’t stop with a stop codon, and length not divisible by three). As such, we don’t even know whether it’s in frame, or maybe shifted by a nucleotide.

comment Why cancer is not a communicable disease?
I’m unhappy with this answer, and although I haven’t downvoted it, let me try explaining why it was downvoted. First of all, as you note yourself later on, your initial sentence is simply wrong: many cancers are caused by infectious agents. More importantly though, your premise is fundamentally flawed: again, as you show yourself, cancer itself is an infectious agent (ever heard of metastases?). So why, then, is it usually not transmissible between individuals? Your answer doesn’t explain that at all.

comment What were the first neural systems like?
@ChrisStronks We know tons about evolution that isn't preserved at all in the fossil record. For instance, we can study evolutionary model organisms and do comparative genomics. In fact, fossils play a fairly minor role in the modern study of evolution.
