In 1966, Andre Jagendorf and Ernest Uribe published a paper on experiments to study hydrogen ion concentrations and ATP production during photosynthesis. The investigators isolated chloroplasts from spinach leaves and disrupted them so that chemical reagents added during the experiment would have access to the thylakoids. These broken chloroplasts were soaked in a “first solution” hydrogen ion concentration and then transferred to a fresh “second solution” of hydrogen ion concentration to create a hydrogen ion concentration gradient across the thylakoid membrane. This second solution also contained ADP and inorganic phosphate. The rate of ATP production was measured from the second solution. This table summarizes Jagendorf and Uribe’s results. Hydrogen Ion Concentration (nmol/liter) Trial # First Solution Second Solution Rate of ATP synthesis 1 10,000 5.0 4 nmol/mg 2 25,000 5.0 11 nmol/mg 3 159,000 5.0 28 nmol/mg 4 63.0 63.0 0 nmol/mg 5 10,000 63.0 0 nmol/mg 6 25,000 63.0 0.5 nmol/mg 7 159,000 63.0 8 nmol/mg

In the diagram, which part is often broken during CPR due to incorrect positioning of hands?

Use this information for the next three questions. A hospital patient suffering from a chronic internal infection caused by a bacterium was treated with daily injections of the antibiotic streptomycin over a period of 12 days. The following graph shows the results. Graph Representing Antibiotic Treatment Results for Chronic Internal Infections Image Description A graph of the results of antibiotic treatment for a chronic internal infection over a 12-day period. The graph shows two lines: Bacteria per mL Urine (solid line) and Antibiotic Resistance (dashed line). The x-axis represents Days, ranging from 0 to 12. The y-axis on the left represents Bacteria per mL Urine, ranging from 1.0×107 to 9.0×107. The y-axis on the right represents Antibiotic Resistance, ranging from 0 to 60000. The table below summarizes the data points from the graph:  Then there is a Table: Days Bacteria Per mL Urine ×1007 Antibiotic Resistance 1 8 100000 2 7 100000 3 1 100000 4 >.5 100000 5 >.5 400000 6 .5 425000 7 1 500000 8 1.5 475000 9 1.75 500000 10 2 550000 11 2 525000 12 3 550000 (Antibiotic resistance = minimum inhibitory concentration of streptomycin in μg/ml) Which of the following statements correctly describes these experimental data, or a conclusion that can be properly drawn from them?
