The answer is: 'constrict the blood vessels in their large ears to reduce transfer of external heat to the blood in their ears.' This is an example of thermoregulation. Thermoregulation is the ability of the<span> </span>body to keep body temperature<span> within certain boundaries, even when the temperature of the surrounding environment is very different. The regulation of temperature by thermoregulating organisms is one aspect of </span>homeostasis. By using heat exchange systems, such as employed in this example, the animal will need to expend less energy on behavioural adaptations to maintain a constant body temperature.
Answer:
plant leaves contain openings called stomata, which allow the diffusion of gas exchange
