Here’s a specious argument: "According to the simulation, the average temperature of the Earth with the maximum concentration of greenhouse gases is only 10 degrees Fahrenheit warmer than it is today. That’s nothing to worry about. " Explain one thing wrong with this statement

Answers

The statement used the word 'average' in relation to the whole globe. This means that some parts of the earth will experience more warming than others.

Averages and variations

An average is obtained by summing up all the variates in a data set and dividing it by the total number of variates. Thus, a single figure is used to represent the entire data set.

The problem here is that the variations within the data set are hidden with averages.

Using average to represent an increase in the temperature of the earth as a result of increased concentration of greenhouse gases can be dangerous. This is because some parts of the world will experience far larger temperature changes while others will experience lower than the average.

Answer:

Explanation:

Deoxygenated blood from different organs comes to the right atrium through the vena cava.

From the right atrium, blood goes to the right ventricle. The tricuspid valve between the right atrium and right ventricle prevents the backflow of blood.

From the right ventricle, blood goes to the lungs through the pulmonary artery.

Inside the lungs, carbon dioxide is removed from the blood and oxygen enters the blood.

From the lungs, blood goes to the left atrium through the pulmonary vein.

From the left atrium, blood goes to the left ventricle.

From the left ventricle, blood is pumped into the aorta so that it can be supplied to different organs.
