A very active person uses a large amount of energy and therefore has a high a temperature be cholesterol level see fat diet D metabolism

Answer 1

The correct answer is D: metabolism.

A very active person typically has a higher metabolic rate, which refers to the processes by which the body converts food into energy. Higher activity levels often result in increased energy expenditure, which is linked to metabolism. While a person's temperature, cholesterol level, and dietary fat intake can also be affected by activity levels, metabolism is the most directly related to energy use in this context.
