Endotherms are a group of organisms that maintain the temperature of their body mainly by using heat released via their internal functioning instead of depending on ambient heat. In these organisms, the internal sources of heat have the main role in regulating the temperature of the body.

Question

Which of the following is a correct statement about endothermic organisms? A. Compared to ectotherms, since they cannot have their internal body temperature leave the thermoneutral zone, they are limited with regard to the types of environments they can live in. B. Endotherms do not typically use passive mechanisms for thermoregulation, such as insulation, because they utilize metabolic energy to control body temperature. C. The trait of endothermicity is a derived characteristic in mammalian animals and is not seen in other phylogenetic branches in the Metazoan Clade. D. All endotherms possess sweat glands, which allow them to conduct evaporative cooling to lower their body temperature when needed. E. None of the above

Match the body temperature control item to the appropriate location in the negative feedback loop. Effector when variable is low Effector when variable is high Control center Sensor Controlled variable A. Muscles for shivering and goosebumps B. Nerves in skin C. Brain D. Sweat glands E. Temperature

If daytime body temperature of some ectotherms were measured, the values would be fairly constant. Provide an explanation for such observations, giving some possible mechanisms that might be involved
