sergejj [24]

About eighty five percent of the population is heterozygous for the dominant grey tail color trait. (Decimal form 0.85)

I took 15,000 divided by 12750

Next I took my answer (1.1764705882352941176470588235294‬ or 1.17 --> 1.18 (rounded up)) and divided 100 by that number. You would get ‭85.000000000000000000000000000001‬ or 85..

What is responsible for returning nitrogen to the atmosphere as nitrogen gas?
serious [3.7K]

Nitrogen is the most abundant gas in the atmosphere, which is about the 78% of the atmosphere. So the main source of nitrogen gas is the atmosphere air.

<h3>What is responsible for returning nitrogen to the atmosphere as nitrogen gas?</h3>

Denitrification is the process that converts nitrate to nitrogen gas, thus removing bioavailable nitrogen and returning it to the atmosphere. Nitrogen makes up 78 percent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

So we can conclude that: Nitrogen is the most abundant gas in the atmosphere, which is about the 78% of the atmosphere. So the main source of nitrogen gas is the atmosphere air.
