Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answer.
Answer:
[tex]BMR_{women} = 1401.75[/tex]
Explanation:
According to Harris-Benedict equation the Basal metabolic rate of an organism can be calculated by using the following formula for both men and women -
[tex]BMR_{men} = 10 * W + 6.25 * H - ( 5 * A) + 5[/tex]
[tex]BMR_{women} = 10 * W + 6.25 * H - ( 5 * A) - 161[/tex]
Here, W is the weight in Kgs
H is the height in Cms
and A is the age in years
My weight is equal to [tex]65[/tex] Kgs
My height is equal to [tex]167.64[/tex] cms or [tex]5.5[/tex] feet
Gender - female and
Age is [tex]27[/tex] years
Substituting the given values in above equation, we get
[tex]BMR_{women} = 10 * 65 + 6.25 * 167.64 - ( 5 * 27) - 161\\[/tex]
[tex]BMR_{women} = 1401.75[/tex]
Sample Answer:
Brian is a 15-year-old boy who weighs 130 pounds and is 68 inches tall. He engages in moderate exercise.
Convert weight and height to the metric system.
Weight: 130 lbs. = 130 × 0.45 = 58.5 kg
Height: 68 in. = 68 × 2.54 = 172.72 cm
Calculate BMR.
For men, BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + 5 BMR = (10 × 58.5) + (6.25 × 172.72) − (5 × 15) + 5 = 1594.5 calories
Calculate daily calorie needs.
For moderate exercise, daily calories needed = BMR × 1.55 = 1594.5 × 1.55 = 2,471.475 calories

Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.
