Answer to Question 1

A, B, C
Feedback:
Levodopa is a precursor of dopamine, which is deficient in parkinsonism; it crosses the bloodbrain barrier, where it is converted to dopamine and acts as a replacement neurotransmitter; it is effective for 2 to 5 years in relieving the symptoms of Parkinson's disease.

Answer to Question 2

D
Feedback:
During an acute infection, the neutrophils are rapidly produced in response to the interleukins released by active white blood cells. They move to the site of insult to attack the foreign substance. Eosinophils are often increased in an allergic response. Basophils would only increase with generalized bone marrow stimulation. The hematocrit level is increased in polycythemia.
