1. Based on Table 1, the relationship between intensity and wavelength is best represented by which of the following graphs?
2. Based on Figure 2, approximately how long did the bubble take to expand to its maximum radius, and approximately how long after that did the bubble take to contract to its minimum radius?
3. Based on Figure 1, at approximately what time did the acoustic pressure of the sound wave change from negative to positive?
4. Based on Figures 1 and 2, the time at which the flash of light was emitted corresponded most closely with the time when which of the following occurred?
5. Consider the time interval from 5 μs to 25 μs. Based on Figures 1 and 2, when the acoustic pressure had a value of 0.5 atm, the bubble radius was closest to which of the following?
6. Consider the claim 'The bubble radius will not begin to increase until after the acoustic pressure reaches its most negative value.' Do Figures 1 and 2 support this claim?
7. Was the number of unmarked snails captured during the second visit higher for Group 2 or for Group 3?
8. The estimated size of the snail population was smallest for the group assigned which color?
9. Suppose the students plan to repeat the study the next year to determine whether the size of the snail population has changed. Which of the following aspects of the study’s design should be kept constant so that the data from each year can be validly compared?
10. Consider the following steps that were performed in the study. 1. Marking the snails with nail polish 2. Drying the snails’ shells 3. Releasing the snails back into the stream. In the study, these steps were performed in what sequence?
11. Suppose that the nail polish used to mark the snails had worn off some of the snails within 3 days. Which of R and N, if either, would most likely have been affected?
12. The linear distance traveled was measured for a total of how many recaptured snails?
13. What was the minimum linear distance, in centimeters, traveled by a snail recaptured by Group 3?
14. Which of the following tables is most consistent with Student 3’s prediction about how increasing solution temperature affects ICV formation?
15. The results shown in Table 2 are consistent with the prediction(s) of which of the students, if any?
16. Are the data shown in Table 1 consistent with Student 2’s prediction about how ink concentration affects the average number of ICVs formed?
17. Prior to the experiment, with which of the following statements about the effect of ink concentration on ICV formation would both Students 2 and 3 have been likely to agree?
18. Prior to the experiment, for which temperature—22°C or 30°C—would Student 1 most likely have predicted that Tetrahymena would, on average, produce the greatest number of ICVs?
19. Which of the students predicted that the average number of ICVs formed by Tetrahymena is affected by either ink concentration or temperature but not both?
20. Suppose it were determined that, at high ink concentrations, ink particles physically interfere with the ability of Tetrahymena’s plasma membrane to form vesicles. This result would strengthen the prediction(s) of which of the students, if any?
