Endothermic animals can maintain consistent temperature conditions by generating, main-taining, and regulating their body heat.Under cold conditions, more body heat becomes lost to the environment. Endothermic ani-mals rely on different mechanisms that allow them to maintain their body heat.Which of the following mechanisms that occur in endothermic animals does not describe amechanism by which they maintain their body heat under these types of conditions?ABсDSome endothermic animals hibernate during extreme environmental conditions, whichdecreases the rate of metabolic reaction and decreases heat loss.The tissues of the blood vessels of many endothermic animals can dilate and movecloser to the skin, allowing for heat to move more readily into the environment.Shivering, which can occur involuntarily in most endothermic animals, produces rapidmuscle contractions, which increase the rate of cellular respiration and thereby increaseheat production.Layers of densely packed lipid cells under the skin of many endothermic animals pro-vide insulation and trap generated heat.

Endothermic animals are animals that produce their own body heat. Examples of these animals include mammals, birds, and some fish and insects. Examples of mammals include humans, rabbits, cats, and dogs.All the other options are correct except option B. This option is incorrect because this mechanism does not help the endothermic animal to maintain body heat. Instead, it allows for heat to move more readily into the environment, which will result in a decrease in the animal's body temperature. This mechanism does not help the endothermic animal to keep its body temperature at a consistent level. When the blood vessels dilate and move closer to the skin, it allows for heat to be easily released into the environment, which can result in a decrease in the animal's body temperature. Endothermic animals rely on different mechanisms to maintain their body heat, such as shivering, hibernation, and insulation, all of which help retain the body heat, rather than release it. Therefore the correct option is B.
