The thermoneutral zone is the range of body temperatures over which an animal can maintain a constant basal metabolic rate. Which of the following patterns about thermoregulation is true? A. Below the lower critical threshold, animals must decrease their metabolic rate in order to maintain body temperature B. Animals living in the arctic have higher critical temperatures than do animals in the tropics C. When outside temperatures are below the lower critical temperature for an animal, animals in the arctic increase their metabolic rate faster than do animals in the tropics D. All of the above E. None of the above
According to Hall et al., the energy balance system is interactive and complex. True False
Basal Metabolic Rate (BMR) is the amount of energy your body uses to function at rest in a day. This includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning, and the body temperature stabilized. Approximately 70 percent of an individual’s energy expenditure goes into basal metabolism. The other 30 percent goes into digestion and absorption of nutrients (10%) and physical movement (about 20%). Calculate your basal metabolic rate in Calories using the appropriate equation here: Females: BMR = 655 + (9.6 × wt(kg)) + (1.8 × ht(cm)) – (4.7 × age(yrs)) Males: BMR = 66 + (13.7 × wt(kg)) + (5 × ht(cm)) – (6.8 × age(yrs)) Calculate how many Calories you burn overall in a day.
The basal metabolic rate (BMR) represents the (a) maximum energy expenditure when exercising. (b) minimum, resting energy expenditure of an awake, alert person. (c) minimum amount of energy expenditure during light exercise. (d) muscular energy expenditure added to the resting energy expenditure.
