The risk of developing iron deficiency is especially high during pregnancy. Detecting such a deficiency is complicated by the fact that some methods for determining iron status can be affected by the state of pregnancy itself. Consider the following data on transferrin receptor concentration for a sample of women with laboratory evidence of overt iron-deficiency anemia. 15.3 9.2 7.6 11.9 10.4 9.7 20.4 9.4 11.5 8.4 9.4 16.1 (a) Compute the values of the sample mean and median. (Round your answers to four decimal places.) mean = median =

Common symptoms of iron-deficiency anemia include muscle weakness, shortness of breath, and lightheadedness. Why does iron deficiency cause these symptoms? A. Since iron is required for fluid balance, iron deficiency increases the volume of blood that circulates in the body. B. Since iron is required for fluid balance, iron deficiency decreases the volume of blood that circulates in the body. C. Since iron is required make hemoglobin and myoglobin, iron deficiency decreases the amount of carbon dioxide in the blood and in the muscles. D. Since iron is required to make hemoglobin and myoglobin, iron deficiency decreases the amount of oxygen in the blood and in the muscles.

Your doctor has diagnosed you as being anemic-that is, as having too little iron in your blood. At the drugstore, you find two iron-containing dietary supplements: one with iron(II) sulfate, $\mathrm{FeSO}_{4},$ and the other with iron(II) gluconate, $\mathrm{Fe}\left(\mathrm{C}_{6} \mathrm{H}_{11} \mathrm{O}_{7}\right)_{2} .$ If you take $100 . \mathrm{mg}$ of each com- pound, which will deliver more atoms of iron?
