Answer to Question 1

Ans:
B

Feedback:

Erythrocytes contribute to acid-base balance through the production of bicarbonate and hydrogen ions. They contain soluble enzymes but are neither self-replicating nor involved in fluid balance.

Answer to Question 2

Ans:
C

Feedback:

The gamma globulins, antibodies of the immune system, protect against infectious diseases. Because alpha globulin transports bilirubin, a defect in this plasma protein might lead to jaundice; a defect of beta globulin, which transports iron, could be associated with anemia; and a defect of fibrinogen could result in blood clots.
