To draw: The graph that would represent the results from the “study of the correlation between the activity levels of brown fat tissue in research participants, following exposure to cold and their percentage of body fats.”
Introduction:
Brown fat cells generate heat during
To propose: The two hypotheses that can explain these results.
Introduction:
Brown fat cells generate heat during cellular respiration, instead of ATP. Brown fat keeps infants warm. The mitochondria of brown fats have channels that disperse the H+ gradient that the electron transport chain had produced. In this case, the H+ ions do not pass through the ATP synthase. Therefore, ATP is not produced.

- According to your hypothesis about the relationship between temperature and the rate of cellular respiration (as temperature increases, rate of cellular respiration increases and vice versa), answer the following questions: What was the reason that you thought your independent variable would affect the dependent? That is, what cell structures do you think would be affected by the independent variable you chose? (Think of enzymes, membranes, organelles, etc.) What was the reason for the relationship you chose? That is, why did you think the independent variable would make the dependent increase or decrease? What would the results (and graph) look if they did NOT support your claim/hypothesis?arrow_forwardYou are designing an experiment to determine if you can make desert kangaroo rats active at noon. At noon the ground and air are warmer than the internal temperature of the rats. You decide to provide the kangaroo rats with enough water to ensure they can maintain body temperature homeostasis. Based on a simplified model, you determine that at noon, kangaroo rats: - Absorb 8 watts of radiation - Generate 1 watt of metabolic heat - Re-radiate 1 watt - Exchange a total of 2 watts with the surrounding desert ground and air via conduction - Exchange 4 watts through convective processes The kangaroo rat is not in energy balance. Since kangaroo rats lose 1 watt through latent heat (i.e. evaporative cooling) with each 2 ml of water consumed, how much water would you need to provide the kangaroo rat so that it can reach homeostasis? 04 8. O 12 O24 O 28 32arrow_forwardAfter a long, hot run together, your friend tells you that you should dunk your head into a cooler of water to lower your body temperature more rapidly, rather than sitting and waiting to cool down. What do you think? Form a hypothesis, about how the ice-cold water might affect the rate at which your body temperature returns to normal. How could you test your hypothesis? Explain your answer.arrow_forward
- Chapter 3 discussed the importance of increasing your walking pace to achieve optimal health benefits. The chapter even discussed how walking at such increased speeds could help you burn calories like a runner. Was this information surprising to you? That is, were you surprised to learn that by just increasing your pace, you could burn the same amount of calories as someone running as their physical activity?arrow_forwardYou are designing an experiment to determine if you can make desert kangaroo rats active at noon. At noon the ground and air are warmer than the internal temperature of the rats. You decide to provide the kangaroo rats with enough water to ensure they can maintain body temperature homeostasis. Based on a simplified model, you determine that at noon, kangaroo rats: - Gain 8 watts of heat from radiation and 1 watt of heat from metabolism - Lose 1 watt of heat by re-radiation - Gain 6 watts of heat from the surrounding desert ground and air via conduction and convection The kangaroo rat is not in energy balance. Since kangaroo rats lose 1 watt through latent heat (i.e. evaporative cooling) with each 2 ml of water consumed, how much water would you need to provide the kangaroo rat so that it can reach homeostasis? 4 8. 12 24 28 O 32arrow_forwardWhich statement best describes the diagrams shown? https://images.app.goo.gl/xAnVmHYPHudXsoYj7arrow_forward
- You are studying the effect of different drinks on tooth enamel. In your experiment you place pieces of chalk in different drinks to record the time it takes for the chalk to completely dissolve A. Identify the dependent variable B. Identify the independent variable C. List two constantsarrow_forwardBotox is a toxin produced by the bacterium Clostridium botulinum. When ingested with tainted food, Botox can kill by paralyzing muscles needed for breathing and heartbeat. Physicians inject small quantities of diluted Botox into facial muscles to paralyze them and reduce the appearance of wrinkles. Some people have expressed concern about a trend in which people come together for “Botox parties” at hair salons and other nonmedical settings. What are the risks of getting injections in such a setting?arrow_forwardTay–Sachs disease is a devastating genetic neurological disorder caused by the lack of an enzyme that degrades a specific lipid molecule. When this molecule accumulates in brain cells, an otherwise healthy child undergoes motor and mental deterioration within months after birth and dies by the age of 3 years. In general terms, describe how a system biologist evaluates this phenomenon?arrow_forward
- material (DNA) stored within cach and dys During high intensity, short-duration exercise (weight lifting, for example), fatigue is believed to be partially caused by: 29. A. The decrease in extracellular Calcium caused by sweating. B. The increase in extracellular Potassium and increase in intracellular ADP ca used by the activity of the muscle fibers. C. The decrease in localized temperature that occurs in active muscle fibers. D. The decrease in intracellular Sodium caused by the Action Potential.arrow_forwardWhat labels would you use to describe an animal that cannot use its metabolism to generate heat but homeostatically regulates its body temperature around a specific set point using other means? Explain your reasoning.arrow_forwardWhich of the following statements describe a characteristic of the human body? a. Under certain conditions your body’s resistance can be low as a few hundred ohms. b. The lower the resistance of your body, the more current that can be forced through it by a given amount of voltage. c. The resistance of your body is lower than the normal when you are wet. d. All of the above. EXPLAINarrow_forward
