Answer to Question 1

ANS: C
When iron is deficient, the concentration of transferrin receptors increases. They are decreased in chronic disease. Erythropoietin and transferrin concentration do not affect the concentration of transferrin receptors.

Answer to Question 2

ANS: B
Only the insoluble form of storage iron, which is hemosiderin, stains with the Prussian blue stain. Ferritin is soluble and is not stained.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
