Which feature distinguishes the innate immune response from the adaptive immune response?
Answer and explanation
Correct answer: D. Innate responses are immediate and non-specific, with no memory of earlier infections
- Step 1: Innate defences such as skin, inflammation, phagocytes and natural killer cells act at once against many pathogens.
- Step 2: Adaptive responses are specific to an antigen and produce memory cells.
Answer
immediate, non-specific, no memory.
Why not the others: Slow, specific and memory-forming describes the adaptive response; antigen presentation by T cells and antibodies from B cells are also adaptive features.
