Summary Introduction
Introduction:
Thermoregulation is a mechanism by which the internal temperature of the body is maintained by exchanging heat with the surroundings. It occurs in ectothermal animals like fishes and amphibians. The endothermal animals have an internal mechanism for regulating and maintaining the temperature inside their body by the generation of energy in the
Therefore, the ectotherms and endotherms differ in the mechanism of the regulation of heat exchange inside the body due to the mechanism of thermoregulation.

Which of the following statements is True?a. Ectotherms generate most of their body heatmetabolically.b. Ectotherms include birds and mammals.c. Ectotherms experience variable body temperatures.d. Ectotherms are known as “warm-blooded” animals.
Which of the following is a correct statement about endothermic organisms?
A. Compared to ectotherms, since they cannot have their internal body temperature leave the thermoneutral zone, they are limited with regard to the types of environments they can live in.
B. Endotherms do not typically use passive mechanisms for thermoregulation, such as insulation, because they utilize metabolic energy to control body temperature.
C. The trait of endothermicity is a derived characteristic in mammalian animals and is not seen in other phylogenetic branches in the Metazoan Clade.
D. All endotherms possess sweat glands, which allow them to conduct evaporative cooling to lower their body temperature when needed.
E. None of the above
Which statement regarding thermoregulation is TRUE?
ectotherms thermoregulate by moving between sunny and shady locations whereas endotherms do not thermoregulate
endotherms thermoregulate by producing heat through metabolic reactions whereas ectotherms do not thermoregulate
ectotherms and endotherms both thermoregulate, but they do it through different methods

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.

- 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_forwardSome animals fall between endothermic and ectothermic. a) What is this thermoregulation category called?
