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.
A student claimed that anoles are endotherms. Which of the following explains why this claim is incorrect? Anoles are:
Correct answer: D
Explanation
A. Incorrect. The passage stated that anoles are reptiles, not amphibians. Reptiles are ectotherms (cold-blooded animals that primarily absorb heat from the surrounding environment to maintain body temperature), not endotherms (warm-blooded animals that primarily generate heat from internal metabolic processes to maintain body temperature).
B. Incorrect. The passage stated that anoles are reptiles, not amphibians. Reptiles are ectotherms (cold-blooded animals that primarily absorb heat from the surrounding environment to maintain body temperature).
C. Incorrect. The passage stated that anoles are reptiles. Reptiles are ectotherms (cold-blooded animals that primarily absorb heat from the surrounding environment to maintain body temperature), not endotherms (warm-blooded animals that primarily generate heat from internal metabolic processes to maintain body temperature).
D. Correct. The passage states that anoles are reptiles, not amphibians. The student claimed that reptiles are endotherms (warm-blooded animals that primarily generate heat from internal metabolic processes to maintain body temperature). However, reptiles, including anoles, are ectotherms (cold-blooded animals that primarily absorb heat from the surrounding environment to maintain body temperature).
