What is the primary function of the innate immune system?

To coordinate the adaptive immune response against specific antigens

To recognize and respond to a wide variety of molecular patterns associated with microbes and damaged host cells (correct)

To produce antibodies that neutralize foreign substances

To provide long-lasting, specific immunity against pathogens

Which of the following is a key feature that distinguishes innate and adaptive immunity?

Innate immunity provides long-lasting memory responses, while adaptive immunity does not

Innate immunity has limited diversity, while adaptive immunity has a very large diversity of antigen receptors (correct)

Innate immunity is specific for self-molecules, while adaptive immunity is not

Innate immunity involves only cellular components, while adaptive immunity involves both cellular and humoral components
