Which is a circulating antibody to protect the body fluids?
1 \(\operatorname{Ig} \mathrm{D}\)
2 \(\operatorname{Ig} Z\)
3 Ig G
4 \(\operatorname{Ig} \mathrm{A}\)
Explanation:
About \(75-80 \%\) of normal human serum is IgG. It is the most common type of antibody. It provides long term resistance to a disease. Booster injection of vaccine raises the level of IgG antibody.IgG of maternal antibodies cross the placenta and provide passive immunity to the foetus and child upto the age of 6 months.

Identify \(A\) and \(B\) in the following figure.
1 A - heavy chain, B - light chain
2 A - light chain, B - heavy chain
3 A - light chain, B - light chain
4 A - heavy chain, B - heavy chain
Explanation:
Antibody molecules have a common structure of four polypeptide chains, having two different sizes. These are a pair of identical high molecular weight chains called Heavy chains (H-chains) and a pair of identical low molecular weight chains called Light chains (L-chains).

Transplantation of tissues/organs to save certain patients often fails due to rejection of such tissues/organs by the patient. Which type of immune response is responsible for such rejections?
1 Auto-immune response
2 Humoral immune response
3 Physiological immune response
4 Cell-mediated immune response
Explanation:
Cell-mediated immune response

The main reason, why antibodies could not solve all the problems of bacteria mediated diseases is
1 Development of mutant strains resistant to antibodies
2 Inactivation of antibodies by bacterial enzymes
3 Decreased efficiency of the immune system
4 Insensitivity of the individual following prolonged exposure to antibiotics. Protozoan disease (Malaria)
Explanation:
Bacteria develop mutant strains that become resistant to antibodies, so these antibodies become incapable of removing bacteria mediated diseases.
