Animals can be divided into endotherma and ectotherms based on how their body temperature is regulated. Endotherms maintain a constant internal body temperature, whereas ectotherms have a body temperature that is dependent on the external temperature. Fishes, amphibians and reptiles are ectotherms, whereas aves and mammals are endotherms.
Frog is an example of ectotherm, that undergoes winter sleep (hibernation) as well as summer sleep (aestivation). Hence, the given statement is True.

An ectotherm is an animal whose body temperature can fluctuate with the environment. These animals may...

Humans and warm-blooded animals maintain a constant body temperature, which is typically higher than their environment. A. Estimate the maximum efficiency of a thermodynamic engine that is powered by this temperature difference in moderate climate conditions (the living organism is the hot reservoir and the environment is the cold reservoir). Take the temperature of the human body about 37∘C and assume a temperature of 8 ∘C for the environment. B. Determine the output power of such an engine if the...

1. Which of the following statements is FALSE? Homeotherms can sustain a high level of physical activity for long periods. Homeotherms require a very low amount of glucose for daily activities. Homeotherms can generate energy rapidly when the situation demands. Homeothermy allows organisms to function at a higher level in cold environments. Homeotherms have relatively higher metabolic rates than similar-sized poikilotherms. 2. Larger terrestrial animals (mammals, birds, and reptiles) acquire oxygen through __________. their skin air sacs the membranes in...

(33%) Problem 3: Warm blooded animals are homeothermic that is, they maintain an approximately constant body temperature. (For humans it's about 37°C.) When they are in an environment that is below their optimum temperature, they use energy derived from chemical reactions within their bodies to warm them up. One of the ways that animals lose energy to their environment is through radiation. Every object emits electromagnetic radiation that depends on its temperature. For very hot objects like the sun, that...

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...
