Question

the basal metabolic rate (bmr) is the amount of energy that must be consumed by a person at rest to maintain his or her body weight. bmr depends on several factors, including sex, age, height, and weight. this graph shows the bmr for a 6 - foot tall 45 - year - old male. how many more calories would a 240 - pound man need to consume than a 170 - pound man to maintain a constant weight? 70 calories 100 calories 300 calories 2000 calories part b - thinking critically which two statements about basal metabolic rate are true? if you exercise vigorously, you will need to consume fewer calories than your bmr suggests to maintain a constant weight. if you lose weight, your bmr will not change. the basal metabolic rate determines exactly how many calories to consume each day. basal metabolic rate includes the energy consumed by the body during cellular respiration.

Explanation:

Step1: Locate values on graph

Find BMR for 240 - pound and 170 - pound man on the BMR - by - weight graph.

Step2: Calculate difference

Let \(BMR_{240}\) be BMR for 240 - pound man and \(BMR_{170}\) be BMR for 170 - pound man. From the graph, \(BMR_{240}\approx1500\) calories and \(BMR_{170}\approx1800\) calories. The difference \(\Delta BMR=BMR_{240}-BMR_{170}=1500 - 1800=- 300\) calories. The absolute value of the difference is 300 calories.

Answer:

300 calories
