Many leading taxonomists have grouped chimpanzees and humans into the same family, hominidae, because

The classification of humans, gibbons and orangs, chimps and gorillas in the same family of hominidae is based on the morphological similarities between the three types of organisms. Moreover, taxonomists also incorporate the genetics of these organisms, and the current molecular-based cladistic classification groups all of these organisms in to the same monophyletic group.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.

Ithink the answer is c. i’m not sure though i’ll notify you when i have an exact answer!
