Answer to Question 1

C
Individuals who have the genetic phenotype MM (or M phenotype) have normal levels 1-antitrypsin.

Answer to Question 2

C
An increase in the a-v difference is due to a decrease in cardiac output (circulatory hypoxia). The cardiac output and a-v difference are inversely related, and an a-v difference of 9.9 vol.  is evidence of the inadequacy of the cardiac output.
