Step 1
D. action of memory cells when an individual is subjected to a second infection of measles.
Answer
Specific immunity refers to the adaptive immune response that targets specific pathogens. In this context, the action of memory cells, which are a hallmark of the adaptive immune system, plays a crucial role. When an individual encounters a pathogen for the first time, the immune system creates memory cells that remember that specific pathogen. Upon subsequent infections, these memory cells enable a faster and more effective immune response, providing long-lasting immunity.
