The correct Answer is:
To solve the question, we need to analyze both statements provided about amphibians. ### Step-by-Step Solution: **Step 1: Analyze Statement 1** - Statement 1 claims that "Amphibians often hibernate in winter and aestivate in summer." - Hibernation is a state of inactivity and metabolic depression in animals during winter, while aestivation is a similar state during hot or dry periods (summer). - Amphibians do indeed exhibit these behaviors to survive extreme temperatures and conditions. Therefore, Statement 1 is **correct**. **Step 2: Analyze Statement 2** - Statement 2 states that "They are poikilothermic animals and cannot regulate body temperature." - Poikilothermic animals, also known as cold-blooded animals, cannot maintain a constant body temperature and rely on environmental temperatures. - This is true for amphibians, as they are unable to regulate their body temperature internally. Hence, Statement 2 is also **correct**. **Step 3: Conclusion** - Since both Statement 1 and Statement 2 are correct, the correct option is that both statements are true. ### Final Answer: Both statements are correct. ---
