Consider the following graph with metabolic rate on the left y-axis (grey line) and
mass-specific metabolic rate on the right y-axis (black line):

Body Mass (kg)

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?

- a) Use your sketching and writing skills to explain the relationship between metabolic rate (M) and body weight (W): M = aWb b) Based on your answer to question a), generate a new graph to explain how the exponent b in the allometric relationship changes between different groups of animals; and what would happen graphically if M is expressed per gram of body weight: M/W =aW(b-1)arrow_forwardOne food calorie = 1 X 103 calories = 1 kcal. A typical adult ingests about 2200 food calories per day. (A) show that an adult uses energy at about the same rate as a 100-W light bulb. {B) Calculate the total annual metabolic energy expenditure of the 6 X 109 people on the earth and compare it with the 4 X 1020 J per year energy used by the world economy. Assume all persons consume 2200 food calories per day, which is obviously incorrect.arrow_forwardBasal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) Calculate how many Calories you burn overall in a day.arrow_forward

- Explain three factors that affect an animal’s metabolic rate.arrow_forwardWhich of the following states about Basal Metabolic Rate is NOT true? A) Basal Metabolic Rate is linearl proportional to weight B) Basal Metabolic Rate is the amount of energy need to maintain body functions C) Basal Metabolic Rate represents the energy needs of a human at rest D) As size increase Basal Metabolic Rate also increases E) Basal Metabolic Rate can be measured indirectly via oxygen consumptionarrow_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_forward
- 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_forwardIf the circulatory system of an ob/ob mouse is surgically joined to that of a normal mouse, what will be the eff ect on the appetite and weight of the ob/ob mouse?arrow_forward
