1 $\lg G$
2 $\lg \mathrm{D}$
3 $\lg \mathrm{M}$

An insect bite may result in inflammation of that spot. This is triggered by the alarm chemicals such as:
1 histamine and dopamine
2 histamine and kinins
3 interferons and opsonin
4 interferons and histones
Explanation:
B An insect bite may result in inflammation of that spot. This is triggered by the alarm chemicals such as histamine and kinins. Histamine is a chemical messenger that mediates several cellular responses. Kinins are produced and secreted by the liver cells. The other inflammatory mediators are tryptase, cytokines, interleukins, etc.

Lysis of foreign cell is mediated through
1 IgM only
2 IgM and IgG
3 IgA only
4 IgD and IgE.
Explanation:
B Lysis of foreign cell is mediated through IgM and IgG. IgG and IgM both are involved in lysis of foreign cell through mediator. Actually both these antibodies occur in the blood. If antigens (Foreign cells), somehow enter into the blood then (IgG and $\operatorname{Ig} M$ ) bind to these antigens and thus, enhance the effectiveness of phagocytic cells. These phagocytic cells through the process of endocytosis engulf the foreign cells. Immunoglobulin G accounts for $80 \%$ of all antibodies in serum while immunoglobulin $\mathrm{M}$ is largest antibody accounts for $5 \%$ to $10 \%$ for all the antibodies in the serum.

Immunity tolerance developed by
1 Interaction with the antigen
2 By giving antibodies
3 Present by birth
4 By giving antibiotics
Explanation:
A Immunological tolerance is a state of immune unresponsiveness specific to a particular antigen or set of antigens induced by previous exposure to that antigen or set. Tolerance is generally accepted to be an active process and in essence, a learning experience for $\mathrm{T}$ cells.
