When climbing a hill or mountain, there are different condions which the body reacts to, first: the body begins to exercise, since it must carry all our weight when climbing up a hill, this generates that the heart accelerates and pumps the blood more quickly so that it reaches our whole body out, and the second one, is that at a higher height, less oxygen, if already, our body comes with the heart shaken by the physical exercise, now it has to accelerate your breathing to get the necessary oxygen for the blood and the body, these two things make us breathe heavily.
I am not thinking of a creature but of a tree which is the gingko tree which was in existence back 200 million years ago and there is one on a street where we lived in Vancouver BC and they grow in various parts of the world still. The coelocanth is a prehistoric fish which still lives in the sea also. I think that evolutionists would view such living 'fossils' as proof that these organisms were so well adapted to a wide range of environments or were able to find environments that they originally thrived in that they could survive so long. Also, probably the longer they survived changed conditions the tougher they would get. A creationist would say aha that shows that species don't change and evolve which of course would deny the overwhelming evidence of the change in species through time such as amongst man's ancestors.
No, cells are not dependent on the size of the organism.
