Answer 1

41.

Peyer's patches are lymphoid follicles seen in the small intestine. They prevent growth of bacteria in the small intestine.

Peyer's patches are located in the Small intestine.

Other options are incorrect. Peyer's patches are not found in oral cavity, large intestine or throughout the body.

Small intestine is the answer.

42.

The statement is False.

Thymus gland doesnot increases in size as we age. Thymus gland decreases in size as we age.

False.

43.

IgG antibodies are the type of antibodies that clinicians interested in detecting in recovered patients. IgG antibodies remain in blood after an infection is passed.

Other options are incorrect.

44.

The type of immunity would occur from a vaccine for COVID - 19 based on its genetic sequence - Artificially acquired active immunity.

Artifically acquired active immunity is obtained through a vaccine , which contain antigens. Other options are incorrect.

45.

Ability of an antibody to bind pathogenic components of toxins and block its toxic effects- Neutralization.

Neutralization is the process in which antibodies bind to the specific parts of the toxins and neutralize them.

Other options are wrong. Inflammation is a response to harmful stimuli. Opsonization is the process of tagging pathogens for phagocytosis. Agglutination is the aggregation of antibodies and antigens.  

46.

Antibodies are secreted by Plasma cells.

B cells differentiate into plasma cells and secrete antibodies.

Other options are incorrect. Antibodies are not secreted by T cells, dendritic cells or antigen presenting cells.

Plasma cells is the answer.

47.

Cardinal signs of inflammation are - redness. heat, swelling, pain and loss of function.

Bruising is not cardinal sign of inflammation.

Bruising is the answer.

48.

The statement is true.

Class II MHC molecules are found only on surface of  antigen presenting cells ( Dendritic cells, B cells, mononuclear phagocytes )

True.

49.

The group of 30 plasma antimicrobial proteins that are activated in a series of enzymatic reactions- Complement.

Complement proteins are produced by liver , activated by pathogens leading to cascade of reactions.

Other options are incorrect. Interferons are proteins released by virus infected cells. Immunoglobins are antibodies. Lysozymes are enzymes present in body fluids.

Complement is the answer.

50.

Helper T cells are reduced in AIDS.

Other options are incorrect.

Helper T cells is the answer.
