What is the best description of the chromosomes by the end of metaphase of mitosis? a- the chromosomes separate at the centromere and begin to move apart b- the chromosomes reach opposite sides of the cell and begin to be incorporated into two new nuclei c- the chromosomes have coiled and become more compact d- the chromosome pairs collect in a line across the middle of the cell(20 )

The answer to this problem is B- The chromosomes reach opposite sides of the cell and begin to be incorporated into two new nuclei. :D hope it helps...

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.
