Answer #1

Answer) option a & c both (Humoral Immunity and Cell-mediated immunity)

Adaptive immunity which occurs once the body is exposed, either via a pathogen or vaccine, to an antigen. Adaptive immunity has memory and is much more particular to antigen as compared to innate immunity. When the innate immune response is insufficient to eradicate pathogen and control infection, Adaptive immunity is activated at that time. the adaptive response could not occur without getting information from the innate immune system.

The two types of adaptive responses are mentioned below:

  1. Cell-mediated immune response - Controlled by T cells
  2. Humoral immune response - Controlled by B cells and antibodies

Adaptive immunity provides long term protection to host from same type of pathogen by keeping a memory. In case of re-exposure of same pathogen, the memory will lead to quick and effective response.

A host organism needs time, often days, to mount an immune response against a new antigen, but memory cells permit a rapid response to pathogens previously encountered. A vaccine to protect against a particular viral infection often consists of weakened or killed virus or isolated proteins from a viral protein coat. When injected into a person, the vaccine generally does not cause an infection and illness, but it effectively teaches the immune system what the viral particles look like, stimulating...

Adaptive immunity has several features that distinguish it from innate immunity. Specificity in that each adaptive immune response is induced by a particular antigen, or surface feature that generates an antibody. An innate immune response might be stimulated by a PAMP, while an adaptive immune response is stimulated by a single feature of a bacteria. In addition, cells of adaptive immunity, B and T cells, are allowed to proliferate under certain conditions to mount a defense, this feature is clonality...
