Answer to Question 1

ANS: B
Erythrocyte concentrations of 2,3-DPG in banked blood decrease over time. After a week of storage, the 2,3-DPG level may be less than one-third of the normal value.

Answer to Question 2

ANS: A
The impact of changes in blood pH on hemoglobin affinity for O2 is called the Bohr effect. As shown in Figure 12-10, the Bohr effect alters the position of the HbO2 dissociation curve. A low pH (acidity) shifts the curve to the right, decreasing Hb affinity for O2 and thus O2 saturation.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
