Question 10

Answer 1

Answer:

C. They expend 50 to 65 percent of their energy on basal metabolism.

Explanation:

A sedentary individual refers to an individual who typically has a lifestyle that involves little or no physical activity such as exercising, jogging, push-ups or sit-ups.

This ultimately implies that, sedentary individuals while engaging in their daily life activities such as writing, watching television, listening to music, reading, etc, they are usually found to sit or lie down for much of the time spent on such activities.

Also, basal metabolism can be defined as the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.

Hence, the statement which is true for sedentary individuals is that, they expend 50 to 65 percent of their energy on basal metabolism.

Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.
