Question
Which of the following is a feature true for the adaptive immune response only?ANSWERIt kills invaders.It distinguishes self from foreign.It is effective against diverse threats.The response is tailored to a specific antigen.
Solution
The feature that is true only for the adaptive immune response is "The response is tailored to a specific antigen."
Here's why:
-
"It kills invaders." - This is a feature of both the innate and adaptive immune responses. The innate immune response can kill invaders directly through phagocytosis or indirectly by activating the adaptive immune response.
-
"It distinguishes self from foreign." - This is also a feature of both the innate and adaptive immune responses. The innate immune system recognizes general features of pathogens, while the adaptive immune system recognizes specific antigens.
-
"It is effective against diverse threats." - Again, this is a feature of both the innate and adaptive immune responses. The innate immune response is broad and can respond to a wide range of pathogens, while the adaptive immune response is more specific but can adapt to recognize a wide range of antigens.
-
"The response is tailored to a specific antigen." - This is a feature unique to the adaptive immune response. The adaptive immune response is able to recognize and remember specific antigens, allowing it to mount a stronger response upon subsequent exposures to the same antigen. This is the basis for immunological memory and is why vaccines work.
