Answer:
If temperature drops, it is negative feedback whereas if the temperature increases, it is positive feedback.
Explanation:
When the temperature drops from 98.30 °F, it means it is a negative feedback because its response is negative while if the temperature increases from 98.30 °F, it means it is a positive feedback because its response is positive. From 12 am to 3 am which represents negative feedback, temperature decreases whereas from 3 am to 6 am, the temperature increases which indicates positive feedback. From 6 am to 9 am, again the temperature drops and this fall represents negative feedback and so on.
