The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the type of organisms that can maintain a constant internal temperature. This is a key concept in biology related to thermoregulation. 2. **Analyzing the Options**: The options provided are: - A) Homeotherm - B) Poikilotherm - C) Urethotherm - D) Stenotherm 3. **Defining Homeotherm**: Homeotherms are organisms that can maintain a stable internal body temperature regardless of external environmental conditions. This means they can regulate their body temperature effectively. 4. **Defining Poikilotherm**: Poikilotherms are organisms that cannot regulate their body temperature. Their internal temperature fluctuates with the external environment. 5. **Defining Urethotherm**: Urethotherm is not a standard term in biology. It seems to be a misinterpretation. However, if we consider endotherms, they can function across a wide range of ambient temperatures but do not maintain a constant temperature. 6. **Defining Stenotherm**: Stenotherms are organisms that can only survive within a narrow range of temperatures. They are not capable of maintaining a constant internal temperature. 7. **Conclusion**: Based on the definitions and the understanding of thermoregulation, the correct answer to the question is **A) Homeotherm**. Homeotherms are the organisms that can maintain a constant internal temperature. **Final Answer**: Homeotherm ---
