A population of 50% brown and 50% gray squirrels live in a forest. A forest fire kills 20% of the brown squirrels and 90% of the gray squirrels. The new population of squirrels is now mostly brown squirrels. What type of evolution is presented in the scenario?

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.
