Question

What is the difference between innate and adaptive immune responses?

a) Innate immunity is rapid and specific, while adaptive immunity is slow and non-specific.
b) Innate immunity has memory, while adaptive immunity lacks memory.
c) Innate immunity is the first line of defense, while adaptive immunity is the second line of defense.
d) Innate immunity is present at birth, while adaptive immunity develops after exposure to pathogens.

Answer 1

The innate immune response is rapid and nonspecific, while the adaptive immune response is slower but highly specific and has memory.

Step-by-step explanation:

The innate immune response is the first line of defense against pathogens. It is rapid and nonspecific, meaning it responds quickly to any pathogen but does not have memory. The adaptive immune response, on the other hand, is slower but highly specific and effective at attacking a wide variety of pathogens. It develops after exposure to specific antigens and has memory to provide long-term protection. Therefore, option d) Innate immunity is present at birth, while adaptive immunity develops after exposure to pathogens is the correct choice.
