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
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 variationsAn 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.

Describe the flow blood through the heart of human beings
gud mrng y'all
Answer:
Heyy
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.

Answer:
This means that individuals use sounds and written symbols to represent objects, actions, events, and ideas. The second property of a language system is that language is generative. This means that a small number of symbols can be combined in an endless variety of ways to create many messages. The third property of a language system is that language is structured. This means that specific rules govern the way words are arranged and the way sentences are made so that communication is effective. B. F. Skinner claimed that the nativist theory is the accurate theory to explain the process of language development.

Answer:
Cytosine and Thymine
Explanation:
Of the four DNA bases, (C, T, A and G), C and T are pyrimidines. The way I remember it is, C, U (which is only in RNA) and T are "pyrimidines", which has more than 3 syllables, hence there are 3 bases in this category, as compared to purines which only contain 2 (A and G).
