- Ectotherms use more energy to maintain their body temperature than endotherms are better able to carry out intense, long-duration activity than endotherms have a more constant internal body temperature than endotherms gain most of their heat from external sources have a higher metabolic rate than similarly-sized endothermsDuring intense exercises and when muscles are working harder, our cells metabolize glucose rapidly resulting to oxygen molecules being quickly consumed. Which of the following becomes the human body's coping mechanism in response to limited oxygen supply? faster breathing and lower blood circulation slower breathing and faster blood circulation faster breathing and faster blood circulation slower breathing and slower blood circulationWhich 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-blooded
- Which of the following statements is not true? a. Essential nutrients can be synthesized by the body. b. Vitamins are required in small quantities for bodily function. c. Some amino acids can be synthesized by the body, while others need to be obtained from diet. d. Vitamins come in two categories: fat-soluble and water-soluble.constrict The regulation of body temperature is an example of a(n) mechanism because an above-normal body temperature stimulates mechanisms to decrease it, while a below- normal temperature causes changes to bring it up. dilate Вook positive feedback Print The thermostat is located in the part of the brain called the blood vessels erences hypothalamus When the core body temperature falls below normal, the negative feedback of the skin constrict and then receive nerve impulses to induce shivering to generate heat. sweat glands skeletal muscles When the body temperature is higher than normal, the blood vessels of the skin and the nervous system activates to cool the body by evaporation. cerebellum Reset1.One pound of body fat is the energy equivalent of calories. 2.
