Question

which of the following is not a characteristic of specific immunity?
antigen specificity
memory response
rapid response to pathogens
production of antibodies
question 8 (bonus) (1 point)
what is the primary function of memory cells in the immune system?
long - term immunity upon re - exposure to pathogens
production of antibodies
immediate response to pathogens
question 9 (1 point)
which of the following is not a type of antigen - presenting cell?

Explanation:

• First question: Specific immunity (adaptive immunity) has antigen specificity (recognizes specific antigens), memory response (remembers antigens for future encounters), and production of antibodies (by B - cells). The rapid response to pathogens is a characteristic of innate immunity, not specific immunity.
• Second question: Memory cells in the immune system provide long - term immunity upon re - exposure to pathogens. Antibodies are produced by plasma cells (a type of B - cell), and the immediate response to pathogens is mainly by innate immune cells.

Answer:

• First question: C. Rapid response to pathogens
• Second question: A. Long - term immunity upon re - exposure to pathogens
