<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 temperature increases 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.

Answer:
Genotype of long winged fly is Ll
Genotype of short winged fly is ll
Explanation:
Given
Allele for long wing trait is "L"
Allele for short wing trait is "l"
When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 
Let us say that the genotype of long winged fly is Ll
and the genotype of short winged fly is ll
The cross between the two will produce following offspring
Ll * ll
Ll, Ll, ll, ll
Out of four off spring two have long wings (Ll)
and the other two have short wings (ll)
Thus the ration of long to short wing offspring is 
i.e

Inside your ear there is water this water is detected in your ear and a signal is send to your brains so you know your balanced. If you have an infection. This signal is blocked so you can't feel if you're balanced or not.
