How would life on earth be different if its axis were not tilted with respect to its orbit? a. there would be no seasons. b. there would be no day or night. c. all places would be no day and night. d. the seasons would be mush shorter.

If the Earth was not tilted at all, we would have no seasons at all! If it were tilted differently, the seasons would be of a different length. We would, however, still have day and night as the Earth would keep on rotating, which is what gives us the day and night cycle.

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.
