Predict 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.)
Give an example of a feedback mechanism in the human body. Explain your example briefly. Make sure to identify the type of feedback (negative or positive), the receptor, the control center and the effector.
The role of insulin is to signal the cells to uptake glucose from the blood. Is this a positive or negative feedback loop? Explain what would happen if the other type of feedback loop were to occur.

- The hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forwardThe regulation of temperature in mammals and birds is an example of homeostatis. Design an experiment to observe and measure processes involved in temperature homeostatis in sedentary versus athletic humans during exercise.arrow_forwardUsing your knowledge of the heart, blood vessels and factors affecting blood pressure, create a possible reflex control/feedback loop that would occur if a person's blood pressure suddenly decreases. Include all of the elements of a feedback loop. Your answer can simply be a list of steps that would occur, but make sure to indicate all of the elements of a feedback loop. This does not to be extremely detailed, I am looking for the elements of the feedback loop and to see that you understand the factors affecting blood pressure. I will start the loop: 1. Stimulus: Drop in blood pressure.arrow_forward
- Describe how blood sugar (e.g. glucose plasma concentration) is regulated with the hormones, insulin, and glucagon. For this feedback loop, identify the following components of the feedback loop: stimulus, receptor, control center, efferent pathway, effector, and response. Be comfortable with this feedback loop to be able to describe the effects of changing various components of the feedback loop.arrow_forwardlight stimulus Refer to the figure below to answer the question that follows: 40 Bobcat (endotherm) H Enake (netother) 10 10 40 20 30 Ambient temperature (°C) 51. The diagram above shows the body temperature vs ambient temperature for a bobcat and snake. The Despite this extra energy animal that is expending more energy at lower temperatures is the expenditure, the payoff is that a. snake; it can be active during a wide range of temperatures b. bobcat; it can conserve energy c. snake; it can conserve energy d. bobcat; it can be active during a wide range of temperatures snake; it can hide for longer in Mr. vonk's physics room e. Body temperature (°C) 20arrow_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.

- Autism is a condition that is generally characterized by difficulties in communicating, understanding abstract concepts, and forming relationships with other people. Recent studies show that children with autism tend to have low levels of oxytocin. Oxytocin nasal spray has been tried as a medical intervention. List two main functions of oxytocin in the body.arrow_forwardHuman body system is a powerful machine that works all the time. To maintain the system, homeostasis should function regularly. Give TWO (2) examples and discuss the factors that give effect to this selfregulating process.arrow_forwardexplain in in a great detail the positive feedback loop and negative feedback loop in this picturearrow_forward
- Use the drawing of the endomembrane system to explain how a cell would make and secrete insulin protein. Start with the insulin mRNA entering the cytoplasm and end with insulin protein being secreted from the cell. Be sure to describe what happens in each organelle and how the protein travels from one place to another in the cell.arrow_forwardDraw a negative feedback loop for maintaining homeostasis for thermoregulation where your body temperature is above the set point. In your drawing, include the stimulus, sensor, integrator, effector, and the arrows between the components to indicate how they all relate (be sure to indicate what each of these components are in your body, for example, what is your integrator). Further, answer the following two questions. First, what might be different between the response of an endothermic and an ectothermic animal in maintaining homeostasis? Second, describe what a negative feedback loop is and how it pertains to homeostasis.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_forward
