irina [24]

Answer:

A) To make sure that the effect is not occuring through actions in the nervous system

Explanation:

In the above scenario, researchers actually studies the effect of hormone to the organ but they are in a situation to study the effect on organ are either hormone base or nervous system base (neurons). For this reason they will cut the neurons to study the effect of hormone on the organ.

So, to check the effect of hormone they should cut the neurons to make sure these effect are not due to actions of nervous system.

Explain the role of valence electrons and how they relate to the periodic table of elements?
myrzilka [38]

Explanation:

The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.

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
