Briefly discuss why the mass specific metabolic rate of an elephant is much lower than that of a mouse.
Given the shown relationships, which statement is true?
A rabbit has a lower mass-specific metabolic rate than a horse
A rabbit has a higher mass-specific metabolic rate than a horse
O It is impossible to tell from this graph whether a rabbit or a horse has a higher
metabolic rate or higher mass-specific metabolic rate
A rabbit has a higher metabolic rate than a horse
According to Kleiber’s law, for the vast majority of animals, an animal’s metabolic rate is proportional to m 0.75, where m is the animal’s mass. When we plot the graph of the common logarithm of the mass on the horizontal axis and the common logarithm of the metabolic rate on the vertical axis, we get a straight line. Explain why the graph is a straight line. What is the slope of the line?

Given this information, what would be the likely result if ghost crabs in nature experienced conditions that raised their typical body temperature from 15°C to 24°C? Select one: a. Aerobic scope and capacity for aerobic exercise would decrease. b. Aerobic scope would decrease and capacity for aerobic exercise would increase. С. Aerobic scope and capacity for aerobic exercise would increase. d. Aerobic scope would increase and capacity for aerobic exercise would decrease.arrow_forward
- Are the following statements true or false? A. Most of the energy stored in the human body is in the form of fat, followed by protein. The body has only limited capacity for storage of carbohydrate. B. It is estimated that one kg of fat gain requires 2500 kcal of energy surplus. A is true, B is true O A is false, B is true A is true, B is false O A is false, B is falsearrow_forwardSkeletal muscles account for approximately 43% of the typical body mass. At rest, they use about 18% of the BMR. Of the total energy burned by the skeletal muscle, only 25% is used for work, and this is the muscular efficiency. What happens to the remaining 75% of energy? Choose the best answer. It is reabsorbed and stored for later use. It is transferred as electrical energy from the muscle to muscle. It is converted to heat to warm the body. It is used to make more ATP.arrow_forwardAn average adult cheetah has a metabolic mass of 44,010 grams and a resting metabolic rate of 61.77 joules per second.

- With regard to thermoregulation in humans, what could be considered an accurate consequence of the outside temperature dropping below the lower critical temperature? A. The individual will begin to breathe in less oxygen and exhale less carbon dioxide. B. The metabolic needs of the individual will increase if they remain below the lower critical temperature for sufficient time-frames. C. Capillaries (i.e. blood vessels) near the surface of the skin will dilate in order to allow blood to circulate more freely throughout the organism, distributing heat to raise temperature. D. The person's Basal Metabolic Rate will be lowered to match the Standard Metabolic Rate of an ectotherm of comparable size. E. Hormones from the hypothalamus will be released, which lead to the initiation of a positive feedback response that amplifies muscle contraction, leading to shivering.arrow_forwardPredict what would happen to the metabolic rate of the mouse if you increased the temperature. Predict what would happen to the metabolic rate of the mouse if you decreased the temperature (You can make this prediction with text or with lines on your graph). Support your prediction with evidence about endotherms and ectotherms. (Hint: Think about what happens to your body when you get hot or cold.)arrow_forwardAn average adult cheetah has a mass of 44,010 grams and a metabolic rate of 61.77 joules per second.
