N could be a variable, but in most cases, it is referring to an elemnt, in this case it would be nitrogen, one of the four common, most used elements by biologists
The four most important elements for life are carbon, hydrogen, oxygen, and nitrogen. These elements are essential building blocks for biological molecules like proteins, nucleic acids, and carbohydrates that make up living organisms.
Carbon, Hydrogen, Oxygen and Nitrogen.
Carbon, Hydrogen, Nitrogen, and Oxygen are the four most common elements.
Hard to say since you're not mentioning the four elements.
probably sudying sience and getting there masters dagree
The first four elements are oxygen, carbon, hydrogen and nitrogen.They form water, proteins, enzymes, etc.
The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).
Technology has made it possible for biologists to study living things right to their smallest elements. The microscope is a good example of a tool that allows biologists to study the most minute elements of all creatures.
There are four elements. They are these C,H,O,N
oxygen
the iron is the most important
