Explain how decomposed play a role in the dentrification.

Denitrification is the process by which nitrate is reduced to nitrogen gas by soil microbes when oxygen is not present. This process is vital to the recycling of nitrogen for soil health, microbial and plant growth, and animal health. Denitrification can negatively impact global warming through losses of nitrous oxide.

Explanation:

amber has allowed scientists to study dna that has been preserved over millions of years.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
