During a research project, a scientist collects snails from a beach. he finds several snails that have shells of about the same size and shape. however, the shells have very different patterns and colors. how could the scientist best decide whether the snails belong to different species or to the same species?

he could study how the snails develop.

he could examine the snails’ rna and dna.

he could classify the snails according to shell color.

he could look for other physical similarities in the snails.

The answer would be dogs.

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.
