A student walks to school in the morning when the outside temperature is 60°F. When the same student walks home after school, the outside temperature has dropped to 35°F. In this situation, how is thermal homeostasis maintained?

The student's heart rate drops as a negative feedback mechanism to deliver less oxygen to the lungs.

The student begins to sweat as a positive feedback mechanism to reduce the core body temperature.

The student begins to shiver as a negative feedback mechanism to increase the core body temperature.

The student's breathing rate slows as a positive feedback mechanism to deliver more oxygen to the lungs.
