Transcribed Image Text:### QUESTION 38
**This image depicts homeostatic regulation of temperature and the output signals control a heating unit.**
#### Graph Explanation:
The graph displays temperature regulation over time. The x-axis represents time, while the y-axis represents temperature in degrees Celsius (°C).
A few key elements on the graph:
- **Red Line at 30°C** (G): Denotes the setpoint temperature, the target temperature the system aims to maintain.
- **Blue Shade**: Represents the range of acceptable fluctuation around the setpoint, from 29°C to 31°C.
- Points labeled A, B, C, D, E, and F: Indicate significant points in the temperature regulation cycle.
#### Temperature Fluctuation Points:
- **A (approx. 29.3°C)**: Temperature dips below the setpoint.
- **B (approx. 31°C)**: Temperature rises above the setpoint.
- **C (approx. 29.3°C)**: Temperature dips again.
- **D (approx. 31°C)**: Temperature reaches peak above the setpoint.
- **E (approx. 30°C)**: Returns to the target setpoint.
- **F (approx. 28.8°C)**: Temperature dips significantly below the range.
- **G**: Reference to the setpoint line (30°C).
### Multiple Choice Question:
**Which of the following statements is not correct?**
- O The temperature setpoint is 30°C
- O The response loop is activated at the site labeled F
- O The system is regulated via positive feedback
- O The sensitivity of this homeostatic system is ±1°C
