What are two factors that may influence body temperature in a healthy animal?

Body temperature in a healthy animal can indeed be influenced by both weather and exercise. Weather plays a significant role because external temperatures can affect an animal's thermoregulation; for example, in hot weather, an animal may have a lower body temperature due to heat dissipation, while in cold weather, an animal might maintain a warmer body temperature to preserve heat.

Exercise also has a considerable impact on body temperature. When an animal engages in physical activities, its metabolic rate increases, which generates heat and raises body temperature. This is a natural response as the body works harder, and the increased activity level results in a temporary rise in temperature.

Both of these factors—weather conditions and the level of exercise—are integral to understanding how body temperature can fluctuate in response to the animal's environment and physical activity.
