Passage 1 · Science Quiz 1
Green anoles and brown anoles (2 species of reptiles) behave differently when the species are together in a habitat than when the species are in separate habitats. Table 1 lists the anole species present in each of 3 habitats (Habitats X, Y, and Z).
Table 1| Habitat | Anole species present: |
|---|---|
| X | green only |
| Y | green and brown |
| Z | brown only |
Figure 1 shows, for each anole species, the average perching height in a habitat.
Figure 1Table 2 lists the number of times each of Behaviors 1–4Behaviors 1 through 4 was displayed by the anoles in a habitat. Green anoles display Behaviors 1–3Behaviors 1 through 3 only; brown anoles display Behavior 4 only.
Which of the following observations for brown anoles was(were) the same in both Habitats Y and Z?
- Average perching height
- The number of times Behavior 4 was displayed
- Average display time for Behavior 5
Correct answer: F
Explanation
F. Correct. According to Figure 1, the average perching height for brown anoles was 0.6 m in Habitat Y and 0.6 m in Habitat Z. According to Table 2, Behavior 4 was displayed 5 times in Habitat Y and 17 times in Habitat Z. According to Table 3, Behavior 5 was displayed for 49.6 s in Habitat Y and for 33.1 s in Habitat Z. Therefore, only average perching height was the same for brown anoles in both Habitats Y and Z.
G. Incorrect. According to Table 3, the average display time for Behavior 5 was not the same in both Habitats Y and Z.
H. Incorrect. According to Figure 1, the average perching height was the same in Habitats Y and Z. However, according to Table 2, the number of times Behavior 4 was displayed was not the same in both Habitats Y and Z.
J. Incorrect. Neither the number of times Behavior 4 was displayed nor the average display time for Behavior 5 was the same for both Habitats Y and Z.
