3. were there any stages of the cell cycle that you did not observe? how can you explain this using evidence from the cell cycle? 4. as a cell grows, what happens to its surface area to volume ratio? (hint: think of a balloon being blown up). how does this ratio change with respect to cell division? 5. what is the function of mitosis in a cell that is about to divide? 6. what would happen if mitosis were uncontrolled? 7. how accurate were your time predictions for each stage of the cell cycle? 8. discuss one observation that you found interesting while looking at the onion root tip cells.

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.

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process. 

Yes yes yes very good
