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.
Global winds rising near equator and cold air sinking near the poles
Explanation:
Variations in the sun's energy reaching Earth
Changes in the reflectivity of Earth’s atmosphere and surface
Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere
The answer is the last one: amoebas, yeasts, hydras, and ferns
