Answer to Question 1

B
Feedback:
Anemia can occur if erythropoietin levels are low. This is seen in association with renal failure, when the kidneys are no longer able to produce erythropoietin. Low iron levels, hypoxia, and vitamin deficiency are not likely to be the primary cause of anemia in a patient with kidney failure.

Answer to Question 2

D
Feedback:
Norepinephrine is made by the nerve cells using tyrosine, obtained in the diet. Dihydroxyphenylalan ine (dopa) is produced by a nerve, using tyrosine from the diet and other chemicals. With the help of the enzyme dopa decarboxylase, the dopa is converted to dopamine, which in turn is converted to norepinephrine in the axon terminals of adrenergic cells. The norepinephrine then is stored in granules or storage vesicles within the cell.
