Final answer:
Animal B, with a higher body temperature (30°C), would exhale more water vapor than Animal A (25°C), because warmer air holds more water vapor, leading to greater evaporation.
Step-by-step explanation:
The correct answer is B. Animal
When air is warm, it can hold more water vapor compared to cooler air. This is why we often feel more humid during hot days as opposed to colder ones. So, when an animal with a higher body temperature exhales, the air coming out of its lungs will be warmer, and consequently, it will carry more water vapor compared to an animal with a lower body temperature. As the air temperature increases, it can hold more moisture, so animals with higher body temperatures will exhale more water vapor. In this scenario, animal B has a higher body temperature of 30°C compared to animal A's body temperature of 25°C. Therefore, animal B would exhale more water vapor.
In the case of Animal B with a body temperature of 30°C, the exhaled air would be saturated with more water vapor, leading to greater water vapor loss during exhalation compared to Animal A at 25°C. This is similar to the way mammals cool themselves by sweating; as the sweat evaporates from the skin's surface, it removes body heat, and the rate of evaporation increases with the temperature and depending on the humidity.
