4) The graph below shows the level of antibodies in blood for the primary and secondary immune response.
Explain why the production of antibodies/ the level of antibodies in blood is considerably greater in the secondary immune response compared to the primary immune response.
5) Are the antibodies produced to fight off different pathogens the same; is the same antibody produced to fight off influenza and measles? Explain your answer.
6) Some pathogens produce toxins. How does the immune system deal with/ reduce the effects of these toxins?
