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.

Mitosis, a stage in the cell cycle, is important for what reason?
satela [25.4K]

Answer:

A. division of the nucleus

Explanation:

Mitosis is a biological process that the cells of all organisms go through in order to replicate and reproduce. It is part of the cell cycle, which is made up of G1, S, G2, and M (mitosis). In G1, the cell is growing; in S, the DNA of the cell is synthesized, or replicated, so we know choice C is wrong; in G2, the cell is being prepared for mitosis; and finally, in M, the cell actually undergoes cell division.

So, we are looking for an answer choice that involves division: either A or D.

At the end of mitosis, there's an additional process called cytokinesis that actually divides the cytoplasm, so the answer can't be D.

Thus, the answer is A.
