The correct Answer is:
To determine how many activities from the given list are controlled by the hypothalamus, we will analyze each activity one by one. ### Step-by-Step Solution: 1. **Identify the Activities**: The activities we need to evaluate are: - Body temperature - Respiration - Cardiovascular reflexes - Secretion of sexual drive 2. **Evaluate Each Activity**: - **Body Temperature**: The hypothalamus plays a crucial role in thermoregulation, which is the regulation of body temperature. Therefore, this activity is controlled by the hypothalamus. - **Respiration**: Respiration is primarily controlled by the medulla oblongata, not the hypothalamus. Thus, this activity is not controlled by the hypothalamus. - **Cardiovascular Reflexes**: The hypothalamus is involved in the regulation of cardiovascular functions, including heart rate and blood pressure, which are part of homeostasis. Therefore, this activity is controlled by the hypothalamus. - **Secretion of Sexual Drive**: The hypothalamus is also involved in the regulation of libido (sexual drive). Hence, this activity is controlled by the hypothalamus. 3. **Count the Activities Controlled by the Hypothalamus**: - From the analysis: - Body Temperature: Controlled - Respiration: Not Controlled - Cardiovascular Reflexes: Controlled - Secretion of Sexual Drive: Controlled - Total activities controlled by the hypothalamus: 3 (Body Temperature, Cardiovascular Reflexes, Secretion of Sexual Drive) ### Conclusion: The total number of activities controlled by the hypothalamus from the given list is **3**. ---
