A
True
B
False
Verified step by step guidance1
Understand the difference between the innate and adaptive immune responses. The innate immune response is the body's first line of defense and acts immediately or within hours of an antigen's appearance in the body.
Recognize that the adaptive immune response is more specific and takes longer to activate. It involves the activation of lymphocytes and the production of antibodies tailored to specific pathogens.
Recall that the adaptive immune response is characterized by memory, allowing for a faster and more efficient response upon subsequent exposures to the same pathogen.
Identify that the statement in the problem is incorrect because the adaptive immune response is not the first response; the innate immune response is the initial defense mechanism.
Conclude that the correct answer to the problem is 'False' because the adaptive immune response is not the first immune response initiated by the host against a pathogen.
