Nitrogen is returned to the atmosphere during the nitrogen cycle in a process referred to as denitrification.
<h3>What is denitrification?</h3>
It is a process whereby nitrogen becomes mineralized from nitrogenous compounds. In other words, it is the reduction of nitrates to produce elemental nitrogen which is returned to the atmosphere.
Denitrification is a microorganisms-driven process. The nitrates are made to pass through a series of reactions with intermediate products before finally leading to the production of elemental nitrogen.

Answer:
what differences do you observe in the syringe or its contents before the air was pumping into the syringe and after?
Explanation:
When an air bubble enters a vein, it's called a venous air embolism. When an air bubble enters an artery, it's called an arterial air embolism. These air bubbles can travel to your brain, heart, or lungs and cause a heart attack, stroke, or respiratory failure.You can compress it, or squeeze it into a smaller volume. When you push on the plunger you can feel the air pushing back. When you stop pushing, the air inside the syringe will return to its original size.
Answer:
B. because prokaryotes (bacteria) use binary fission instead of mitosis. i hope this works
Answer:
1. There are five primary classes of antibodies, that are IgM, IgG, IgA, IgD, IgE.
2. IgM
Explanation:
The antibodies are proteins that are Y-shaped and are also called immunoglobulins. The antibody is produced when any pathogen attacks the body. There are five primary classes of antibodies, that are IgM, IgG, IgA, IgD, IgE. The antibody contains two heavy and two light chains. The IgM is a pentamer immunoglobulin. The IgG is contains two gamma heavy chains and two light chains. The IgA is mostly monomeric. The IgD have two delta heavy chains and light chains. The IgE contains two ∈ chains and light chains.
IgM is produced first. The IgA produced after IgM on mucosal surfaces. The IgG is present in serum. The all immunoglobulins IgM, IgA, IgD, IgE, and IgG are abundant in blood circulation.
