An advantage to adaptive immunity is . the use of antibodies that cause cell lysis and kill invading cells its need for several cells to be activated over several days on first exposure its memory cells that provide quicker, larger and more efficient immune response upon second and subsequent exposure to an antigen the ability of its individual cells to respond to many different pathogens

It's memory cells that provide quicker ,larger and more efficient immune response upon second and subsequent exposure to an antigen.

Explanation:

Adaptive immunity or acquired immunity is a process whereby some specialized cells in the immune system destroy and eliminate invading pathogens and their toxic molecules they produced. It creates immunological memory through it memory cells of pathogens it encountered before , remember it and act against some antigens. If there is second contact with the antigen it's encountered before, it provide immune response.
