Metabolism and Homeostasis Practice Problems

The mouse has a larger surface area to volume ratio compared to elephants. Hence, which of the following is true?

How does having thorn-shaped leaves help cacti maintain homeostasis?

Which of the following is an example of acclimatization?

_____ animals can naturally regulate their body temperatures while _____ animals have body temperatures that reflect the outside environment.

Mammals like capybaras have constant body temperatures that are usually higher than the temperature in the environment. Capybaras are ______.

How do rodents like capybaras manage their body temperature when the environment is freezing?

The capybara is the largest living rodent and a member of the genus Hydrochoerus. Gigantism, such as in the capybara, results when one lineage evolves extremely large bodies from its small-bodied ancestors. In a specific, confined niche, what will be the consequence of gigantism like that of the capybara in the rodent population?

Which of the following animals has a higher metabolic rate and thus needs to consume more food?

The surface area to volume ratio is important to explain the relationship between the structure and function of various processes, such as the diffusion of oxygen to cells or blood and heat transfer via conduction.
Given the following information on surface area and volume, identify which animal needs to work harder to maintain body warmth.  

As a cell or organism gets bigger, the surface area to volume ratio _______. 

Why do ectotherms not need as much food as endotherms for energy generation? 

Which of the following orders of animals is correctly sequenced based on their metabolic rates? 

Which of the following characteristics is not included in an animal's adaptation to homeostatic regulation in the arctic region?
