Why is oxygen an ideal electron acceptor in cellular respiration? I would guess it's because of its electronegativity but I'm not sure.

Thin discs of fresh potato were cut and separated into batches of ten. Each batch was weighed and placed into one of the six different concentrations of salt solution. Fifteen minutes later the discs were removed, any surface liquid wiped off and then the discs were reweighed. Why would discs left in distilled water not change its mass?

Ok here we go

primordial soup givers rise to amino acids, and protein chains and RNA

but hold on, you need RNA to make amino acids and protiens,
so how can amino acids make RNA, when RNA is needed to make them

ok i called this question EVo, When it's abiogenesis really but still, one supports the other as they suport the theory for millions of years...

but for millions of years how did we get amino acids if you need RNA to make them?

and we couldn't get RNA as we had no amino acids..for millions of years?

even if i added another million there we would still be in a period of activation as we lack the RNA and amino acids and therefore the RNA, yup you see where i am coming from

These are the problems you get when you study evolution and
abiogenesis,

i'm sure you must have the same problems too

your answers please

I know it's to ensure the longevity of the species, but what relevance does this have to the individual? Why does it matter to one person, or mouse, or lion, that their species continues?

Is it because (and I am not well educated so please don't ridicule me) that earth depends on a careful balance, and so that if too many species die the whole of nature would eventually collapsed (and therefore the need to breed is programmed into us at a genetic level)?

Thanks.
