I am not really confident about my answer.
If I am wrong please correct me. <span />
I just did this BTW. The correct answer is A.) Nuclear fusion is the correct answer. Nuclear fission is what we use today in nuclear power plants, a great deal of radioactive waste, the other are by products of this process. Nuclear fusion releases a great deal of energy with a little radioactivity, but the problem is ignition temperatures; but maybe someday.
Because it is meant to be like that for animals , us humans dont need all the stuff that animals do.
C. Exponential growth occurs when there is unlimited resources. Since there is a surplus of food, there are a lot more babies are born because of the favorable circumstances.
