The troposphere is the first layer of the Earth's atmosphere, thus it is the innermost one of all. This is the layer which enables life on our planet, and its composition is just the right one that life on Earth can thrive.
- <em>has the highest air pressure;</em>
Because this layer has the biggest density of all layers, which practically means that it has the most molecules per area, so it is the richest with gasses, this layer has the highest air pressure. The more gasses there are in a layer, the heavier it is, thus it has bigger air pressure.
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other.
