|
|
Adaptive immunity is present at birth and needs to keep a memory of these pathogens over time, but Innate immunity is temporary so it does not a memory of pathogens.
|
|
|
Adaptive immunity is short lived, it keeps a memory of pathogens for future reference, whereas Innate immunity is present at birth so it does not need to keep a memory.
|
|
|
Innate immunity does not fight off pathogens so it cannot keep a record, while Adaptive immunity only fights off pathogens, therefore needing to keep a memory of them.

|
|
None of the above

Detailed explanation-1: -The adaptive immune system provides a diverse set of molecules that can mount specific responses against a multitude of pathogens. Memory is a key feature of adaptive immunity, which allows organisms to respond more readily upon re-infections.
Detailed explanation-2: -Memory immune responses After the first encounter with a pathogen, our immune systems generate a small number of cells that remain for a long time, are specific for that pathogen, and circulate in the blood, spleen and lymph nodes to keep watch for another encounter.
Detailed explanation-3: -These memory cells are primed to proliferate and become active once again if there is a subsequent encounter with that specific pathogen. This allows the immune system to respond quicker and with more force than with the first encounter.
Detailed explanation-4: -The adaptive, or acquired, immune response takes days or even weeks to become established-much longer than the innate response; however, adaptive immunity is more specific to pathogens and has memory. Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination.
