Question

clonal selection of lymphocytes leads to the development of which type of cells? a. effector cells and b cells b. t cells and memory cells c. effector cells and memory cells

Answer 1

b. t cells and memory cells

These immune cells produce a proper response chemical to combat the microbes. The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination.  However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it .
