Solution
This describes a Negative feedback loop (D). Here's why:
-
In a negative feedback loop, the system responds to a change by reversing it. This helps maintain homeostasis, or a stable internal environment.
-
In this case, the dog's body detects a change: its body temperature is too high.
-
The dog's body responds by panting, which helps cool it down.
-
Once the dog's body temperature returns to normal, the panting stops. This reverses the initial change (the high body temperature).
-
Therefore, this is a negative feedback loop because the system (the dog's body) reversed the change (high body temperature) by initiating a response (panting).
