Answer to Question 1

Ans:
A

Feedback:

Decreased cortisol levels are a marker of PTSD and a differentiation from other subtypes of stress. Low levels of norepinephrine and angiotensin II would not accompany any common variant of stress response, and growth hormones are suppressed in response to stress.

Answer to Question 2

Ans:
C

Feedback:

H. pylori, the infectious cause of gastritis and gastric ulcers, produces the urease enzyme on the outer cell wall. The urease converts gastric urea into ammonia, thus neutralizing the acidic environment of the stomach and allowing the organism to survive in this hostile environment.
