1. Based on the information presented, if the transfer of the linear copy was interrupted 50 min after transfer began, how many complete genes would have been transferred to the recipient bacterium?
2. Based on the model presented by Student 3, if all 6 genes are replicated and the first gene replicated is Gene G, the third gene replicated would be:
3. Which students believe that any of the 6 genes on the plasmid can be the first gene transferred to a recipient bacterium?
4. Suppose that the model presented by Student 1 is correct and that the transfer of genes between 2 bacteria was interrupted after 45 min. Based on the information provided, which of the following genes would NOT have been transferred from the donor bacterium to the recipient bacterium?
5. Suppose that Student 2’s model is correct and that the transfer of genes between 2 bacteria was interrupted after 30 min. Under these conditions, which of the following genes would definitely NOT be transferred from the donor bacterium to the recipient bacterium?
6. Suppose that all 6 genes are transferred from a donor bacterium to a recipient bacterium. Under this condition, which student(s) would argue that Gene A could be the last gene transferred?
7. Suppose that the transfer of genes between 2 bacteria was interrupted, that the last gene transferred was Gene A, and that no incomplete copies of a gene were transferred. Based on this information, Student 1 would say that transfer was most likely interrupted how many minutes after the transfer began?
8. In Study 4, as time increased from Year 0 to Year 6, the captures/1,000 hr of frugivores:
9. Based on the results of Study 4, how did fragmentation most likely affect the population sizes of insectivores and hummingbirds in the fragments studied?
10. Based on the results of Study 1, if the distance from the center of a 100 m × 100 m plot were 75 m from the nearest clearing, the expected average change in AGTB at the plot over 17 yr would be closest to which of the following values?
11. After examining the results of Study 2, a student concluded that the AGTB at each of the 25 plots remained constant. Which of the following alternative explanations is also consistent with the results?
12. Which of the following sets of results from the studies is least consistent with the prediction proposed by the researchers?
13. In Study 4, the researchers trapped birds for 10,000 hr per year. Thus, how many insectivores were trapped in Year 2?
14. A sample of gray till was recovered from another core taken from a nearby area. Based on these data and the data provided in Figure 1, the sample of gray till corresponds most closely with which till from Figure 1?
15. According to Figure 1, the oldest glacial advance in this area deposited which of the following till layers?
16. According to Figure 1, which of the following statements best describes how the resistivity of the sand and gravel layer compares to the resistivity of the till layers?
17. The average resistivity of the bedrock in the core is most similar to the average resistivity of which of the following till layers?
18. The sediments being deposited at the present time at the site where the core was taken have a much higher CO2 content than any of the tills. Given this information and the information in Figure 1, the CO2 content of sediments recently deposited at the site would most likely be in which of the following ranges?
