Answer:
d. Number of calories one needs to maintain the body in a resting state during a 24-hour period
Step-by-step explanation:
Resting metabolic rate refers to the amount of energy needed by the body to maintain the vital processes for the duration of 24 hours that occur even if the person is resting. Some of these processes are digestion of food, respiration, urine formation, etc. Resting metabolic rate depends on the physiological conditions of the individuals.
For example, exercises help build the mass and strength of the muscles and increase the resting metabolic rate so that a person can eat more of the food without gaining weight. A person with a slower resting metabolic rate gains weight if not doing any physical activities.
