Answer:
Organisms maintain dynamic homeostasis through behavioral and physiological mechanisms. Which of the following statements is an accurate explanation of a negative feedback mechanism used by animals to regulate body temperature? C) A ground squirrel's hypothalamus detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production
Explanation:
The temperature-regulating center of vertebrate animals is located in the hypothalamus. A ground squirrel's in there detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production. Maintenance of homeostasis usually involves negative feedback loops.
