Which of the following is true about the adaptive immune system? Check all please. Adaptive immunity develops several days after the initial infection, but eliminate pathogens in a specific manner and is saved as memory to encounter the same reinfection Adaptive immunity is improved with repeated infections with the same pathogen A robust primary adaptive immunity can be generated in the absence of innate immunity Adaptive immune cells are B cells that make antibodies and T cells that eliminate infected cells and make cytokines Dendritic cells present antigens to T cells, whereas macrophages present antigens to B cells.

Match the type or cause of clonal expansion with the correct situation. Use each choice just one time and make the best match. Clonal expansion of B cells because the cells are infected with EBV Clonal expansion of B-cells because these B-cells have B Cell Receptors that recognize a non-self antigen Clonal expansion of T-cells that have a T Cell Receptor that recognizes EBV antigens A. normal adaptive response by the B cells B. part of pathogenesis of mono C. This allows the adaptive immune system to shut down active EBV infection
