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_forward
- Thermoregulation 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_forwardEndothermic 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.

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.)arrow_forward
- As the temperature surrounding an endotherm decreases from its normal body temperature down to the freezing point of water, what happens to the amount of energy consumed by this animal? The amount of energy consumed decreases There is no change in the amount of energy consumed The amount of energy consumed increasesarrow_forwardIn a fully grown animal (i.e., one that is not growing), ingested energy becomes O excreted chemical energy + absorbed chemical energy. O heat + chemical energy accumulated in body tissues. heat + excreted chemical energy + mechanical energy of external work + absorbed energy O heat + absorbed chemical energy.arrow_forwardWhich of the following is a way that the body determines how much of a certain chemical, protein, enzyme, or response is needed to maintain homeostasis?
