What is the di?erence between innate & adaptive immunity?A) Innate immunity is present at birth while adaptive immunity is acquired after exposure to pathogens.B) Innate immunity is specific to particular pathogens while adaptive immunity is nonspecific.C) Innate immunity is mediated by antibodies while adaptive immunity is mediated by T cells.D) Innate immunity provides long-term protection while adaptive immunity provides only short-term protection.

A) Innate immunity is present at birth while adaptive immunity is acquired after exposure to pathogens.Innate immunity is the first line of defense & present at birth, it includes physical/chemical barriers. (Skin, mucous membranes, antimicrobial peptides, macrophages, natural killer cells).Adaptive immunity is acquired after exposure to pathogens, it involves production of antibodies & activation of T cells specific to particular pathogens. It's longer to develop but more specific/targeted.
