comment Can brain cells move?
Do you consider the cells of a malignant brain tumor "brain cells"? Because they do move when invading the tissue.

comment How is satiety measured?
I am aware that the wording is not especially good for biology, but I had to migrate. The feeling of satiety has nothing to do with cooking, and the human physiology of eating food is strictly off topic on cooking.se. It is probably a bit more confusing because the OP imagines something which doesn't (and cannot) exist: some kind of universal scale saying that pasta is X times more filling than bread. But an explanation how the feeling of satiety emerges, as the reason why the scale doesn't exist, can be quite interesting.

comment Does eating antacid (such as Magnesia) before meal have any impact on digestion?
What language was the lecture in? In German, Natronlauge is a name for sodium lye (NaOH), which will cause extensive chemical burns long before it reaches the stomach. But the word Natron is used for baking soda (sodium bicarbonate), which will not cause immediate wounds. Still, it's not a good idea to eat it, it disrupts the chemical balance of the stomach. I have a relative who, after prolonged use of sodium bicarbonate, got a bad case of GERD, but cannot say if the soda caused it, or if he would have gotten it anyway and the soda failed to prevent it.

now that I read the question again, I may have misunderstood it. I have to make a pro forma edit before I can remove the downvote. But I have to wait for the peer review.

comment How did aquatic dinosaurs go extinct?
Interesting info, but the aquatic dinosaurs went extinct millions of years before the meteor. So, this doesn't answer the question.

comment About animal ecology and one view of this in science fiction
I agree that the question is formulated very badly, has a strong philosophical bent, and could be interpreted in different ways. But there is a surprisingly simple answer: all interpretations I can think of are false. Animals do not strive towards maintaining environmental balance, neither consciously or unconsciously. The existing balance is a byproduct of the sum of their independent non-cooperative actions.

comment How are arms different than legs?
Why do they have to be defined physiologically? It is a matter of common everyday language, and human language is generally inconsistent and full of "because we've always called it this way" and "because they look similar" reasons. Do you have any example of any scientific research which divides appendages in "arms" and "legs" and proves results which are true for the one and not for the other? Maybe if you got to stuff which is about gripping, or bearing weight, but then you are back at the informal language level.

comment Why does botulinum toxin seem to be more dangerous to humans than to other mammals?
From a food safety point of view, you don't get botulism from "carcasses" (meat). Common botulism vectors are plants, especially the parts growing around dirt (making homemade garlic oil is a really bad idea), and honey (a danger to infants, adults can stomach the spores and they can't form a colony of living bacteria in honey). So, if there are animals which come frequently into contact with botulism, they aren't vultures. Actually, I might have to write an answer about that...
