As the right side of a frog's heart receives deoxygenated blood from the body, and the left side receives freshly oxygenated blood from the lungs, the two streams of blood mix together in the ventricle, sending out a concoction that is not fully oxygenated to the rest of the frog's body.

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

Legionella tends to form biofilms and infect other microbial cells as intracellular pathogens.

Explanation:

The Legionella genus of the bacteria is a group of gram-negative bacteria that can cause legionnaires disease.

The<em> Legionella pneumophila</em> is a species of this genus which can cause legion pneumonia. The bacteria lives in the freshwater and is resistant to chemical treatment like chlorine and the biocide treatment.

The reason for this resistance is since this species form a polysaccharide layer around the colony of the bacteria which is resistant to these treatments and also the bacteria prove parasitic to the protozoans which feed on these bacteria.

Thus, the selected option is the correct answer.

If an object is having a constant positive acceleration, what can we assume about the forces on it?
tensa zangetsu [6.8K]

Answer:

If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. ... If however, the forces are balanced (in equilibrium) and there is no net force, the object will not accelerate and the velocity will remain constant.
