- An average adult cheetah has a metabolic mass of 44,010 grams and a resting metabolic rate of 61.77 joules per second. Based on these data, would you characterize the cheetah as an ectotherm or endotherm? Support your answer with evidence from the graph.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.)Endothermic homeotherms, like mammals, maintain a high internal body temperature, whereas ectothermic poikilotherms, like some reptiles, have internal body temperatures that fluctuate depending on the ambient temperature of their environment. Based on their metabolism, why might mammals have determinate growth whereas some reptiles have indeterminate growth?
- Consider the following energy demands: basal metabolism, reproduction, thermoregulation, activity, and growth; How should the energy spent toward these demands differ between an endotherm and an ectotherm of the same size?You are studying a large tropical reptile that has a high and relatively stable body temperature. How do you determine whether this animal is an endotherm or an ectotherm? (A) You know from its high and stable body temperature that it must be an endotherm. (B) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. (C) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. (D) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm.Please construct a model to show that the digestive, respiratory, and circulatory systems work together to supply the body cells with the glucose and oxygen needed for aerobic cellular respiration. Feel free to use words, diagrams, arrows, flowcharts, etc. to get your ideas across. Make sure you include the following information: Digestion of starch into glucose and the location(s) of digestion. Absorption of glucose into the blood and the location of absorption. Blood transporting glucose from the absorption site to the tissues. Glucose entering the tissue cells from the blood. O2 entering the blood in the lungs and the specific location of entrance in the lungs. Blood transporting O2 from the lungs into the tissues. O2 enters the tissues from the blood.
- Consider an ectotherm and an endotherm of equal body mass. Which of the following would you expect to be true? -both animals require the same amount of energy per unit mass -the ectotherm requires more daily calories from food than the endotherm -the endotherm requires less energy per unit mass but more total energy than the ectotherm -the ectotherm requires less energy per unit mass but more total energy than the endotherm -the ectotherm could survive a longer period without food relative to the endothermWhich of the following are negative physiological feedback loops? Group of answer choices Osmoregulation in mammals Thermoregulation in mammals Generation of action potential in animal neurons Physiological mechanisms leading to labor and birth in eutherian mammals pH maintenance in animal cellsResearch the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation? Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions: ectotherm in cool conditions ectotherm in hot conditions Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.
- Aside from the ones already discussed about childbirth and blood pressure give another example of the feedback mechanism in the human body.Explain your answer briefly by filling out Table B. Table A is given as a patternlight 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) 20The cell is the basic unit of all living things. Some organisms like Amoeba and bacteria are only one cell. Viruses are sub-cellular. Plants and animals are multicellular. Analyze how this fact is important when considering how different organism feed, respire, and excrete. Give two examples for each characteristic and use a multi- cellular organism and a uni-cellular (one-celled) organism to compare.
