Extracted text: 1. When encountering antigen, describe the mechanism of antigen presentation by B cells. 2. Compare / contrast the advantages and disadvantages of active immunity with passive immunity. 3. Does antibody directly destroy a microbe? EXPLAIN. 4. Use the following terms to construct a coherent mechanism for cell mediated immunity: Interleukin, perforin, CD4 cells, CD8 cells, dendritic cells, MHC class I and class II 5. Upon invasion by a microbial antigen with multiple epitopes (antigenic determinants), What makes clonal selection for T cells and B cells relevant? 6. Why have different classes of antibodies (i.e. IgD, IgE)? 7. Why is the primary and secondary responses to antigen important for the host and for clinical diagnosis? 8. Are all adaptive immune responses the same? EXPLAIN.
