Answer to Question 1

ANS: D
IgM is the first antibody made in response to an infection. Adult levels of IgG are reached by 1 year of age. Children attain an adult level of IgA by 5 years of age. IgE is important in the response against fungus spores, animal dander, and pollen.

Answer to Question 2

ANS: A
Vaccinations provide one type of active immunity. Passive immunity is brought about through immunoglobulins, either passed via the mother or given to the child through another means. Innate protection is provided by physical barriers, such as the skin or mucous membranes. Man-made immunity is not a classification of immunity.
