A very active person uses a large amount of energy and therefore has a high

Options:

Temperature

Cholesterol level

Fat diet

Metabolism

Metabolism

The correct answer is "Metabolism".

To determine which option is correct, we need to understand the concept being described and how it relates to a person who uses a large amount of energy.

The term "energy" in this context refers to the amount of calories burned by the body during physical activities. An active person engages in regular exercise or physical exertion, which naturally requires more energy expenditure.

Now, let's assess each option and see which one aligns with the information provided:

1. Temperature: While physical activity can increase body temperature temporarily, it does not necessarily indicate a consistently high body temperature in an active person. Therefore, this option is not the correct answer.

2. Cholesterol level: Cholesterol is a fatty substance found in the blood. Physical activity generally has a positive effect on cholesterol levels, helping to reduce "bad" (LDL) cholesterol and increase "good" (HDL) cholesterol. Consequently, a very active person is less likely to have a high cholesterol level. So, this option is not the correct answer.

3. Fat diet: The phrase "fat diet" is not a common term in nutrition. If you refer to a diet high in fat content, it is important to note that an active person may consume a varying amount of fats based on their personal dietary choices. However, their level of physical activity would likely offset the effect of a high-fat diet to some extent. Therefore, this option is not the correct answer.

4. Metabolism: Metabolism refers to the chemical processes in the body that convert food into energy. A person with a high metabolism tends to burn calories more efficiently and at a faster rate, allowing them to use a larger amount of energy. Therefore, the correct answer is "metabolism."

So, the correct answer is: Metabolism. An active person uses a large amount of energy due to having a high metabolism.
