Use the Harris-Benedict equation to estimate your calorie needs. Show your calculations to explain how you arrived at your answe
Ratling [72]

Answer:

The Harris Benedict Equation is a formula that determines the total daily energy expenditure (calories) using BMR with some activity factors.

Basal Metabolic Rate (BMR) is defined as the amount of calories one would burn without doing anything for 24 hours. It uses variables of weight, age, height and gender to calculate BMR.

<em>BMR calculation =  447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)</em>

<em>In</em><em> </em><em>Harris Benedict Equation, </em><u><em>BMR</em></u><em> is </em><u><em>multiplied</em></u><em> by </em><u><em>activity factor </em></u><em>to determine calories need.</em>

The activity factors in Harris Benedict Equation are:

for no exercise =  1.2

exercise for 1 to 3 days/week or light exercise =  1.375

exercise for 3-5 days/week or moderate exercise  = 1.55

exercise for 6-7 days a week or hard exercise = 1.725

exercise for 2 times training = 1.9

<u>So, calculation for my calorie needs is as following:</u>

BMR = 447.593 + (9.247 x 50 kg) + (3.098 x 164.592 cm) - (4.330 x 23 in years) = 974.945

Calorie needs = BMR x 1.55

                        = 974.945 x 1.55

                        = 1511.16 calories

Photophores are:
Kobotan [32]

Answer:

B) cells or tissue that produce light

Explanation:

It wouldn't be A because photophores do not affect the color of other organisms.

It wouldn't be C because the cells produce light, they don't necessarily change color.

Lastly, it wouldn't be D because it isn't a whole organism producing the light, it's an organ. Organs are multiple tissues working together, and tissues are groups of cells.
