Answer 1

Q. No 1. Answer :

Immunogen is defined as it is any antigen that is that is having capacity of inducing or producing a cell mediated immune response rather than immunological tolerance, this ability can called as immunogenicity.

The nature of immunogens have foreignness, high molecular weight and chemical complexity.

Q. No 2 . Answer

Immunogen : it is a molecule that is capacity of increasing immune response by organisms immune system.

It is necessarly an antigen .

Antigen : it is a molecule that is having capacity to binding to the product of that immune response.

But antigen is not necessarly to immunogen.

Q. No 5 . Answer :

Haptens are minute moleculs, that shows an immune response only when attached to a large carriers such as proteins.

* Haptens are low molecular weight moleculs.

* these are small organic molecules and these are antigenics but not immunogenics.

* these are can binds to immune cells but fails to induce or produce cell mediated immune response.

Q. No 7. Answer :

Adjuvents are the substances which are increases the body immune response to an antigens.

Roles :

* These are stimulates the in activated vaccines should act like immune response.

* These are increases the immune response.

* These are used to determine the effectiveness or ineffective ness of immune response .
