Nitrogen and Carbon make up amino acids, that create proteins.
Phosphates make up DNA and ATP energy which allows for the transport of proteins and lipids in and out of a cell.
What is the question or paper? there isn’t really a question here if there is nothing to look at lol
The reason that organisms have common and scientific names is because there has to be a universal name for all organisms in theory.
Common names can be many different things, dependent on the area of the world you live in, Scientific Names are part of a series called <em>binomial nomenclature </em> which is a universal way to name all organisms. For example, a goose will be called <em>anser anser</em> across the world, then it changes some when you go into breeds, but for the most part, you can get by with that name.
