Answer to Question 1

C
Feedback:
The skin is the first line of barrier defense. It acts as a physical barrier to protect the internal tissues and organs of the body. Mast cells are part of cellular defense. They are found in the respiratory and GI tracts and are fixed basophils that do not circulate. Mucous membranes are a barrier defense that line the areas of the body that are exposed to external influences but do not have the benefit of skin protection. T cells are part of the immune response and provide cell-mediated immunity. Activation of a T cell by a nonself-cell results in responses that destroy foreign cells.

Answer to Question 2

C
Feedback:
Parkinson's disease is a chronic, progressive, and degenerative disorder of the central nervous system (CNS) characterized by abnormalities in movement and posture (e.g., tremor, bradykinesia, joint and muscular rigidity, postural instability).
