Answer to Question 1

ANS: D
Hemosiderin is responsible for the color changes in a black eye. Transferrin is a transport protein responsible for iron transport. Bilirubin is the normal, yellow-to-green pigment of bile derived from the porphyrin structure of hemoglobin. Albumin is the protein in the serum, responsible for cellular integrity.

Answer to Question 2

ANS: B
Coagulative necrosis occurs primarily in the kidneys, heart, and adrenal glands and commonly results from hypoxia. Karyorrhexis means fragmentation of the nucleus into smaller particles or nuclear dust. Ammonia accumulation is not associated with this toxicity. Caseous necrosis re-sults from tuberculosis pulmonary infection.
