30 points hurry the nucleus of any atom requires a strong force to hold it together. this strong force is required because a) the nucleus of any atom is so small. b) protons and neutrons repel each other. c) positive protons in the nucleus repel each other. d) the charges of the protons and the electrons cancel each other out.

The answer should be B) protons and neutrons repel eachother. the protons and neutrons have opposite charges and repel eachother, so of course the nucleus needs to have a very strong force to hold it all together :P

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.
