comment Why do we pass out when we are under attack?
That's a significantly different question. Please edit and clarify.

comment Why do we pass out when we are under attack?
That's like asking why a clock stops if you hit it with a stick. Of course it would be more advantageous to remain conscious. It would also be advantageous to remain alive without a working heart. Unfortunately, our bodies are machines and, like all machines, stop working when they are damaged.

comment Merge several .ab1 sequence files into a single FASTA file?
Ah. That complicates things. Can you somehow export them as fasta? As any kind of text? I have never been forced to work with any kind of closed or binary format so I have very little experience there. Chromas seems to be able to export to FASTA though.

comment Merge several .ab1 sequence files into a single FASTA file?
This is probably better suited to Unix & Linux. If you do ask there, make sure to include examples of your input files. I don't know the ab1 format, what does it look like? Is it fasta? Are you just looking for cat *ab1 > out.fa ?

comment Does your iris color have an effect on your vision?
@AstroMax If this answer solved your issue, please take a moment and accept it by clicking on the check mark to the left. That will mark the question as answered and is the way thanks are expressed on the Stack Exchange sites.

comment Can plants feel pain?
I think @Remi.b meant that it was, when it lacked a definition of pain. Now, it's just virtually impossible to answer :). Can anything with no CNS feel pain? Perhaps not but everything alive (just about, and including plants) will try to move away from harm. Does that mean they feel pain?

comment Can plants feel pain?
@wythagoras the Stack Exchange network of sites (to which this site belongs) doesn't do opinion. We're "just the facts, ma'am". A question where multiple answers are valid ("What's your favorite flower") is a bad fit for this site and will be closed as "primarily opinion based". For more on the type of question we deal with, see biology.stackexchange.com/help/dont-ask

comment Can plants feel pain?
You'll have to define what you mean by "pain". If you define it as "a signal informing the organism of damage", then yes, they do. If you refer to pain as your or I would feel it, that's a different matter.

comment Where’s the flaw in my proposed TB Treatment?
@Lefty good heavens, of course not! Even if your theory worked, it also implies extensive hospitalization. More, in fact, than antibiotic treatment. The patients would need to be hospitalized for the full duration of the treatment, the concentrations of the various gases constantly monitored, doctors and nurses hovering for days etc.

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 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.

An African or European pigeon?

comment Consequence of Plants as Incomplete Protein Source
@Roland I admit I'm biased since I did my PhD on selenoproteins but it's not that rare. There are 22-25 proteins (depending on how you count them) in the human genome and some animals have many more. They are also essential, those animals that have them can't really survive without them. But yes, I know I'm being pedantic, it's just that it's my field and everyone forgets about poor Sec :)

comment Consequence of Plants as Incomplete Protein Source
I changed the 20 to 21 amino acids since most species also code for selenocysteine.
