Defense of the body against a particular pathogen is provided

Defense against a particular antigen is provided by adaptive immunity which is also called specific immunity. In adaptive immunity immunological memory is created which is used by immune cells to destroy that particular pathogen when it again comes in the body.

Adaptive immunity involves T cells and B cells. T cells generate cell mediated immune response and B cells generate a humoral immune response. These responses by T and B cells are specific to a particular pathogen which results in the killing of the pathogen by their phagocytosis enhanced by antibodies or by direct killing of pathogen.

Therefore adaptive immunity provides defense to the body against a particular pathogen by generating immunological memory.

The correct answer will be- specific immune response

Explanation:

The immune response of the body is the response of the fluid and cells of the body to the foreign substance called antigen.

The immune response could be innate immune response provided by the physical and chemical barriers of the body like mucus and skin.

The immune response is against a particular pathogen is known as the specific immune response which recognizes the invading antigen through lymphocytes.

Thus, the specific immune response is the correct answer.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
