comment Which ORF will be translated
Please edit your question and clarify. The answer could be ORF1, ORF2 or both or neither depending on the details. Is this in a species that has introns? Is the RNA spliced? Mature? Are these the same gene? What exactly do you mean by ORF? Are they both terminated by a STOP codon?

comment Why does human hair grow over our eyes
Given that all ones needs to do is tie their hair behind their neck, something that early hominids were perfectly capable of doing, WISIWIG is quite right and there simple was and is no selective pressure to loose this trait. I'm afraid that, simplistic as it may sound, that is the answer. Evolution is not directed, it doesn't have an end goal, if there's no selective pressure, there's no change.

comment Which of the cell types commonly found in mammals has the greatest number of mitochondria?
That's fine, just paste the URL as is and someone can edit it for you. Your answer makes a lot of sense, and I agree that it is very likely going to be muscle cells, but neither of your references support it. They just explain what mitochondria are. I would particularly like to see a reference supporting your claim about photoreceptor cells, that's an interesting point. I can't accept this since you're just giving numbers with no references.

comment Normal death experience
That is a very different question. It asks whether a specific cause of death is painful, citing a scientific paper that claims it is not. You are asking whether we can say that in general, death is preceded by suffering. That is really not a good question for the site as it has nothing to do with biology. There are several hundred thousand ways to die. Obviously some will be painful and some will not. I don't see what we can add to that.

comment Normal death experience
I'm voting to close this question as off-topic because it about philosophical musings on death and not biology.

comment Can all animals of the same species crossbreed?
Whether dogs (Canis familliaris or Canis lupus familliaris) and wolves (Canis lupus) are the same species is debatable. I believe the modern consensus tends towards considering them different subspecies of the same species but as far as I know, the details are not entirely clear. Remember that the line between species is blurry at best.

comment What is the mass of a pigeon tail feather?
@ChrisH I think (no idea really) that pigeon feathers, being relatively large (I'm thinking of entire plumes here, not tiny fluffy ones) would orient themselves pointy end down because of the extra weight of the plume. I may well be wrong though.

comment What is the mass of a pigeon tail feather?
@JanDvorak yes, but we only care about the orientation after it hits the atmosphere. Obviously, there will be no drag coefficient in vacuum. I am guessing that as soon as it hits the atmosphere, the drag will orient it thusly.

comment What is the mass of a pigeon tail feather?
Heh, nothing like the old fashioned empirical approach. I would expect the feather to orient itself with the pointy bit downwards though, it should be relatively standard.
