Answer to Question 1

B

Answer to Question 2

The main role of vitamin C is as an antioxidant, protecting the body from free radicals. Additionally, vitamin C is responsible for the synthesis of collagen and some neurotransmitters. When vitamin C levels are low for a prolonged period of time, the body is more likely to succumb to infections without the presence of the antioxidants. Additionally, the body fails to make sufficient amounts of collagen, which can affect blood vessel function and lead to bleeding. Initially this bleeding is only in the gums and small hemorrhages, but if left unchecked, the patient can develop scurvy symptoms, with teeth falling out and possible internal bleeding. The lack of sufficient collagen can also lead to wounds that cannot heal. Finally, when the body fails to make neurotransmitters, this can lead to the behavioral disorders like depression and hysteria.
