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?A) Squirrels are able to cool themselves during warmer months by producing more brown fat, which contains abundant mitochondria and a rich blood supply. B) Desert jackrabbits have unusually large ears that serve as solar heat collectors to enable them to maintain their body temperatures. C) A ground squirrel's hypothalamus detects changes in environmental temperatures and responds by activating or suppressing metabolic heat production. D) A goldfish slows its movements when the water temperature is lower.
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.
<span>The person who has a small intestine that has fewer villi than normal would most likely be u</span>nderweight. The villi of the small intestines are the small structures that do the absorbing of the nutrients. Having less of these structures, less nutrients are absorbed and the person is more likely to be malnourished.
The second law of thermodynamics is a statement of the law of conservation of energy say that heat cannot be completely converted into mechanical energy
