Step by step
Solved in 2 steps
- 1) It is _____for aquatic vertebrates to maintain a body temperature different from their surroundings because ______. A) easier; water is a much better insulator than air due to its greater density B) easier; it is possible for fish to absorb heat from the surrounding water by countercurrent exchange even when the water is colder than the fish C) harder; water is a better conductor of heat than air D) harder; terestrial vertebrates can use countercurrent exchange to absorb heat from air that is cooler than their bodies 2) Compared to terrestrial environments, marine environments have_____." A) greater differences in temperature between hot and cold seasons B) smaller differences in temperature between hot and cold seasons C) the same amount of seasonal variability in temperatureEndothermic 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…1. What is the purpose of a "Thermal Homeostasis of Gold Fish" lab? 2. Are fish warm-blooded or cold-blooded animals? 3. How do external temperatures affect cold-blooded animals?4. How do external temperatures affect warm-blooded animals? 5. What do you think will happen if you increase/decrease the temperature of a goldfish’s water? 6. What is the hypothesis on the effects of external effects on temperature homeostasis of a goldfish?
- 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?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.The range of regulated body temperatures in mammals is about 36 to 40°C , while in birds it is slightly higher, 38 to 42°C, close to the limit compatible with life. Why do you imagine birds maintain higher body temperatures thanmammals? Do you think eagles and hummingbirds maintain the same body temperatures? Explain.
- 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.)Define the following terms and comment on the limitations (if any) of each in describing the thermal relationships of animals to their environments: poikilothermy, homeothermy, ectothermy, endo-thermyIMPORTANCE OF TEMPERATURE REGULATION IN ANIMALS???
- What are " homeoviscous adaptations "? How does a lizard control it's membrane fluidity on a scorching day ?Draw 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.What animal is not a homeothermic, endothermic, poikilothermic, and ectothermic? and what does this animal do to regulate its body temperature?
