Experiment: During a field study, frogs were exposed to simulated rainfall containing varying pH levels (neutral to acidic). Skin permeability and behavior were monitored.Observation: Frogs in acidic water showed stress behaviors and disrupted ion balance in skin cells.Question: What does the experiment support?
Correct answer: A. Acid rain can disrupt amphibian homeostasis.
- A. Acid rain can disrupt amphibian homeostasis.
- B. Acid rain increases amphibian reproduction.
- C. Skin in frogs resists any pH change.
- D. Acidic water improves survival rates.
Explanation
The correct answer is that acid rain can disrupt amphibian homeostasis. This conclusion is supported by the observed stress behaviors and disrupted ion balance in frogs exposed to acidic water. The other options are incorrect because they do not align with the experiment's results, which demonstrated the negative effects of acidic water on frogs' behavior and skin cells.
