6. Which immunoglobulin is the largest in size?
a) Ig A
b) Ig D
c) Ig E
d) Ig M
View Answer
Explanation: Ig M is the largest immunoglobulin in size. It is the first antibody to appear in the response to initial exposure to an antigen.
7. Antigens are present ___________
a) On cell surface
b) On n nuclear membrane
c) Inside cytoplasm
d) Inside nucleus
View Answer
Explanation: Antigens are a toxic or foreign substance which induces an immune response in the body especially the production of antibody. Antigens are present on the surface of the cell.
8. BCG vaccine is to prevent ____________
a) AIDS
b) TB
c) Cholera
d) Typhoid

Explanation: BCG vaccine is to prevent tuberculosis. BCG stands for Bacillus Calamitte Guerin.
9. Passive immunity can be obtained by injecting _________
a) Antibodies
b) Antigen
c) Vaccination
d) Antibiotics
View Answer
Explanation: Passive immunity is the transfer of active humoral immunity in the form of readymade antibodies. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus through placenta and it can also be induced artificially.
10. Aflatoxins are produced by _________
a) Bacteria
b) Virus
c) Fungus
d) Nematode
View Answer
Explanation: Aflatoxins are produced by a fungus. Aflatoxins are poisonous carcinogens that are produced by some molds which grow in soil, decaying vegetation, hay and grains.
