Answer:
The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N).
Glucose is a hydrocarbon, so it contains carbon (C), and hydrogen (H). It also contains oxygen (O).
Nucleic acids are complex arrangements of carbon, hydrogen, oxygen, nitrogen, and phosphorous.

I believe the answer is A. A single origin of modern people and eventual replacement of archaic homo sapiens throughout Africa, Asia and Europe. Out of Africa model; asserts that modern humans evolved relatively recently in Africa, migrated into Eurasia and replaced all populations which had descended from Homo erectus. After Homo erectus migrated out of Africa the different populations became reproductively isolated, evolving independently, and in some cases like the Neanderthals, into separate species. Homo sapiens arose in one place, probably Africa. Homo sapiens ultimately migrated out of Africa and replaced all other human populations, without interbreeding modern human variation is a relatively recent phenomenon.
Answer:Yes, there is plenty of evidence, maybe to much. Many people throughout the article state many different reasons why red leaves protect the trees. (Maybe you should consider removing some information because it is a little long.)
Explanation: You should remove some of the information because this article
(assuming that you wrote this), is a bit wordy.
ATP means adenosine triphosphate. It consists of carbon, hydrogen, nitrogen, oxygen, and phorphorus, with the formula C10H16N5O13P3. Structurally it is a nucleoside made up of adenine (a nucleobase) and a ribose sugar molecule, with three phosphate groups. It transfers a phosphate group to another molecule to phosphorylate it (give it energy to get the bonds into a transition state).
