Answer to Question 1

Ans:
C

Feedback:

T and B lymphocytes are unique in that they are the only cells in the body capable of recognizing specific antigens present on the surfaces of microbial agents and other pathogens.

Answer to Question 2

Ans:
C

Feedback:

Asthma response begins within 5 to 30 minutes of exposure to an allergen. It is mediated by mast cell degranulation and the release of preformed and/or enzymatically activated mediators. These mediators include histamine, serotonin, and acetylcholine. Histamine is the most recognized mediator of type I hypersensitivity reactions and ultimately results in bronchial constriction.
