<h2><u>Air particles at different layers of the atmosphere</u></h2>
Earth's atmosphere has four layers namely Troposphere, Stratosphere , Mesosphere and Thermosphere where troposphere is nearest to the earth and thermosphere is farthest and temperatureincreases with increase in altitude of the layer of atmosphere. So, temperature is highest in thermosphere and lowest in troposphere. so the ascending order of temperature is Troposphere < Stratosphere < Mesosphere < Thermosphere.
Dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and a small amounts of some other gases by volume. It also contains a varied amount of water vapor, around 1% at sea level, on average and 0.4% over the entire atmosphere.
Decomposition is the process by which dead organic substances are broken down into simpler organic matter such as carbon dioxide , water and mineral salt
The surface of the human red blood cell is dominated by a small number of abundant blood group active proteins. The major proteins are the anion transport protein (band 3) which has AB(H) activity, and Glycophorin A which has MN activity.
