The diagram in Figure 5 shows the difference between negative feedback and positive feedback. (i)Explain why negative feedback is important in homeostasis.              (ii)Explain how negative feedback enables the carotid and aortic bodies and the medulla to maintain a constant blood carbon dioxide level.                    (iii)It is said that the initiation of an Action Potential is an example of positive feedback. With reference to the process involved, state why you think this statement is accurate?
