Question

answer the following questions.

1. choose the best answer.

the basal metabolic rate (bmr) is ______.
the number of total calories needed each day
the number of calories needed for physical functions such as cell development
the rate at which fat burns
a level of physical activity

1. choose the best answer.

what is used as a factor to determine total calories needed?
body weight
a percentage of bmr
a factor based on activity level
age in years

Explanation:

1. BMR refers to the number of calories needed for basic physical functions like cell development at rest. The total daily calorie need is more than BMR (includes activity), fat - burning rate is not the definition of BMR, and it's not a physical activity level.
2. To determine total calories needed, a factor based on activity level (e.g., sedentary, active) is used. Body weight alone is not sufficient (as activity also matters), a percentage of BMR is not the main factor described in standard calorie - need calculations, and age in years is not the key factor here compared to activity level.

Answer:

1. the number of calories needed for physical functions such as cell development
2. a factor based on activity level
