Why are concurrent temperature exchange systems not a part of homeostatic temperature control in endotherms?
The Mojave Desert of the western United States is characterized by a hot, dry climate. Scientists
predict that temperatures in this region will increase by an average of 4.7° F over the next 30 years.
Birds found here (like ground-dwelling roadrunners) are endotherms and have many adaptations to
reduce the amount of heat absorbed into the body while active in the daytime.
If temperatures increase in this area as predicted, how might the plumage (the feathers covering the
body) of these roadrunners change under the influence of natural selection?
1:The plumage will likely become longer and increase heat absorption into the body.
2:The plumage will likely become darker and increase heat absorbed from the environment.
3:The plumaqe will likely become lighter and increase heat reflected away from the body.
4:The plumage will likely become thicker and increase the amount of heat trapped by the body.
Why is it essential for organisms to maintain a relatively constant body temperature? Describe adaptations that help the organisms cope with changes in environmental temperature.

- Endothermic animals can maintain consistent temperature conditions by generating, main- taining, and regulating their body heat. Under cold conditions, more body heat becomes lost to the environment. Endothermic ani- mals rely on different mechanisms that allow them to maintain their body heat. Which of the following mechanisms that occur in endothermic animals does not describe a mechanism by which they maintain their body heat under these types of conditions? A B с D Some endothermic animals hibernate during extreme environmental conditions, which decreases the rate of metabolic reaction and decreases heat loss. The tissues of the blood vessels of many endothermic animals can dilate and move closer to the skin, allowing for heat to move more readily into the environment. Shivering, which can occur involuntarily in most endothermic animals, produces rapid muscle contractions, which increase the rate of cellular respiration and thereby increase heat production. Layers of densely packed…arrow_forwardonly need the what type of feedbackarrow_forwardIn terms of body temperature regulation, contrast “cold-blooded” (Ectothermic or poikilothermic) and “warm-blooded” (Endothermic or homeothermic). Identify three animals that are ectothermic and three animals that are endothermic. What is the adaptive advantage of endothermy?arrow_forward
- Is Thermal Homeostasis of a Gold Fish similar to thermal homeostasis in human? If not, what is the difference?arrow_forwardIn mammals, body temperature is controlled by a structure in the brain called the hypothalamus. The hypothalamus is able to sense even slight variations in body temperature. This structure is responsible for bodily responses that include thirst, the activation of sweat glands, and the dilation of blood vessels near the skin. Each of these mechanisms works to restore body temperature to a normal range.arrow_forwardEndothermy and Ectothermy are two strategies that organisms use to generate or maintain their internal body temperature. An ectotherm is an organism that derives very little of its body temperature internally, and relies on the environment for heat. An endotherm is an organism that maintains its own body at a metabolically favorable temperature by internal means. Question: How does temperature affect endotherms and ectotherms differently? Describe the evidence that will help you make a claim about the question: How does temperature affect endotherms and ectotherms differently?arrow_forward
- for aquatic animals such as sharks, how do the animals maintain their body temperature when they are in warmer or colder waters? do they have a method where they can decrease or increase their body temperatures slightly such as torpor in birds?arrow_forwardA desert beetle’s use of microclimates changes with seasons by temperature. In extremely hot summers, the beetle would need to seek a place that is cooler to regulate its body temperature to prevent overheating. In this season, it would go into underground burrows to avoid the heat above ground. This keeps them cooler during the day. In the evening, beetles lie on the ground to absorb the heat from the daytime to keep warm. This way the beetle regulates its body temperature both a night and during the day. In the cooler season, beetles shade themselves from the sun with the use of shrubs. The shade is efficient enough during that season to maintain their body temperature. If the beetle were to burrow in the cooler season, its body temperature would become too cold. During the winter, the beetle would occupy the ground to receive warmth from the sun. The worst time to be in a burrow would probably be during the cooler season or the winter. The beetle would get too cold if it went in…arrow_forwardexplain in in a great detail the positive feedback loop and negative feedback loop in this picturearrow_forward
- 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.arrow_forwardConsider a lizard and a bird, each of 35g body mass and each with optimal body temperature of 35°C. For each species, draw graphs how its body temperature changes over the course of 24 hours on (i) a cloudy day, and (ii) a sunny day, during SoCal winter (minimum night temp 2°C, maximum day temp 10°C) and summer (minimum night temp 25°C, peak day temp 45°C). Remember that ambient temperatures are always reported for shade. Discuss in detail various heat loss and gain mechanisms (physiologic and behavioural) available to each species which help to explain your graphs. What if one of Dr O's 35kg alligators got loose and started prowling the CSUSB campus? Assuming the same optimal body temperature, how would the alligator's thermoregulation in winter season differ from that of the 35g lizard? How might the gator's thermoregulatory strategy differ before and after it ate the dean? (Alligators regularly devour prey larger than themselves.)arrow_forwardThermoregulation is the process by which animals maintain an internal temperature within a tolerable range. Which of the following statement is NOT TRUE about Thermoregulation ? Lütfen birini seçin: O a. Endothermic animals generate heat by metabolism O b. Ectothermic animals gain heat from external sources O c. In general, ectotherms tolerate greater variation in internal temperature, while endotherms are active at a greater range of external temperatures O d. Ectothermy is more energetically expensive than endothermyarrow_forward
