They might still be under the influence of medication given to them during the surgery. no one under the influence should drive. it is a safety hazard for them to drive
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.
Few factors....
greater concentration differences between regions. I. e. steeper concentration gradient.
lighter molecular mass of substances.
