What is one distinct disadvantage of sexual reproduction?
a) organisms that sexually reproduce do not produce much genetic variety.
b) sexual reproduction, unlike asexual reproduction, can rapidly produce too many new offspring.
c) sexual reproduction requires two individuals, which may be difficult for endangered or uncommon species of organisms.
d) sexual reproduction produces offspring that are all equally vulnerable to the same diseases, predators, and other environmental pressures

You didn’t give us any choices

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.
