- It is important for the body to be able to cool itself even during moderate exercise. Suppose a 70kg man runs on a treadmill for 30min and at a (total) metabolic energy expenditure rate of 1000W remembering that the human body has a 25% efficiency. Suppose also that the man cannot perspire; and cannot lose any heat viaconduction, convection, and radiation. By how much would the man’s body temperature increase at the end of the 30min exercise? Express your answer in oC. A)8.8B)1.4C)0.5D)3.1E)5.7Compared to body size metabolic rate has a slope of 0.75, this means metabolic rate is O faster O slower compared to body size.Thermoregulation is a process used to maintain body temperature within an optimum range. Describe how the human body maintains body temperature in both hot and cold weather ensuring you explain the mechanisms that are involved.
- Basal Metabolic Rate (BMR) depend on All Size of body Mass of bodyWhen you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy that would raise your body temperature if it were not eliminated. The evaporation of perspiration is the primary mechanism for eliminating this energy. Determine the amount of water you lose to evaporation when running for 32 minutes at a rate that uses 400 kcal/h above your BMR. (That amount is often considered to be the "maximum fat-burning" energy output. The latent heat of vaporization of water at room temperature is 2.5 106 J/kg.)The metabolism of 1 gram of fat generates approximately 8.65 kcal of energy and produces approximately 1 gram of water. (The hydrogen atoms in the fat molecule are transferred to oxygen to form water.) What fraction of your need for water will be provided by fat metabolism?An animal living in a cold environment loses heat at a rate that is proportional to its surface area, but its metabolism generates heat in all of its cells, so the rate of heat generation is proportional to its volume. All other factors being equal (which they often are not!), which implications would follow from these facts? Choose all correct responses. Because it is smaller, a baby seal is more at risk for hypothermia (body temperature falling to too low a value) than is an adult when it is in an ocean significantly colder than its body temperature. If you take a baby outdoors on a cold day, you should dress it more warmly than you would dress yourself because it is smaller. If you take a baby outdoors on a cold day, you should dress it less warmly than you would dress yourself because it is smaller. If you take a baby outdoors on a cold day, how cold it feels to you is a good measure of how warmly you should dress that baby. Because it is smaller, a baby seal is less at…

- . Does the penguin or the mouse expend a greater proportion ofits energy budget on thermoregulation? Why?Given that humans thermoregulate, explain why your skin is coolerthan your body core.Using a specific evidence of thermoregulation to support the statement that “The importance of the effect of temperature on physiological function is revealed by adaptations to maintain function at different temperatures”. How exactly is thermoregulation involved as an adaptation?
