- From the list of strategies for dealing with harsh cold environments, choose those that an ectotherm would employ. See image attatched.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 involvedWhich of the following statements is True?a. Ectotherms generate most of their body heatmetabolically.b. Ectotherms include birds and mammals.c. Ectotherms experience variable body temperatures.d. Ectotherms are known as “warm-blooded” animals.
- Although hibernators drop their body temperatures, they do manage maintain a body temperature close to or slightly above ambient temperatures in their burrows. They generate or conserve heat in all of the following ways except one. Which is the one? Non shivering thermogenesis Ruffling the pelage Eating more Calories Bouts of intense shiveringIn the negative feedback system for regulation of body temperature. Identify the following. 1. Stimulus 2. Receptor 3. Control Center 4. Effector 5. ResponseWhich of the following is not a way that ectotherms can change their body temperatures? a. Sweating for evaporative cooling. b. Adjusting the timing of their daily activities. c. Seek out or avoid direct sunlight. d. Huddle in a group.
- Describe the steps in the homeostatic feedback system activated to ensure normal body temperature is maintained when exposed to a hot external temperature (e.g., 42 degrees Celsius). Give typing answer with explanation and conclusionWhich of the following would help increase an endotherm's body temperature? Select ALL that apply. shivering blood vessels narrowing sweating blood vessels wideningEctotherms cannot be considered homeotherms, since they do not use mechanisms to keep their internal body temperatures at a constant temperature. A. True B. False
- Which of the following statements best summarizes the difference between ectothermic and endothermic organisms? Group of answer choices Ectotherms absorb external heat, but endotherms use metabolic heat to maintain a warm, steady body temperature Ectotherms are warm-blooded, but endotherms are cold-blooded Endotherms control their temperature, but ectotherms have no control over their temperature Endotherms are warm-blooded, but ectotherms are cold-bloodedWhich 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 aboveWhich statement regarding thermoregulation is TRUE? ectotherms thermoregulate by moving between sunny and shady locations whereas endotherms do not thermoregulate endotherms thermoregulate by producing heat through metabolic reactions whereas ectotherms do not thermoregulate ectotherms and endotherms both thermoregulate, but they do it through different methods
