Answer:
Nonspecific resistance; adaptive immunity
Explanation:
The immune response against any antigen can be specific or non- specific. The specific immune response is provided by lymphocytes like B lymphocyte and T lymphocytes because after interaction with antigen they differentiate into memory cells which is saved in memory and when that antigen comes again in the body the memory cell easily ward it off. This type of immunity is called adaptive immunity.
In non-specific immunity, memory is not made after interaction and killing of the antigen or microbes by immune cells because the antigen is killed non specifically. Non-specific resistance is provided by phagocytic cells mainly.
