I'm assuming false but really have no clue
The gases like nitrogen and oxygen are not greenhouse gases because they do not absorb infrared radiation.
<h3>What are Greenhouse gases?</h3>
Greenhouse gas is a gas that has the property of absorb infrared radiation from the Earth’s surface and reradiate back to the Earth’s surface, thus contributing to the greenhouse effect.
<h3>What is infrared radiation?</h3>
Infrared radiation is an electromagnetic radiation with wavelengths longer than those of visible light.
Carbon dioxide, nitrous oxide, methane, and water vapour are the most important greenhouse gases.
Hence, nitrogen and oxygen are not greenhouse gases despite being in the atmosphere.

Speed is actually instantaneous speed, the speed an object is moving at that very instant.
But average speed is the total distance traveled divided by the total time.
Let's say you travelled 10 miles in 2 hours, your average speed would be 10 divided by 2, which is 10 miles / hr.
But during those 10 miles you may be accelerating, decelerating and be travelling 1 mile/hour and 20 miles/hour at another point. But your average speed would be total distance / total time. So your instantaneous speed can change throughout that period of time.
That illustration represents the mitochondria
