2. Nitrogen is a natural occurring element with
the symbol N and atomic number 7. It is
crucial for growth and reproduction for plants
and animals. It has no color or odor, and it is
an unreactive gas that creates about 80% of
the earth’s atmosphere.
3. Nitrogen is used in many different ways, not
just inside of biology. It can act as a
substitute for air and create a stable
atmosphere in places like chemical
processing plants and electronic
manufacturing factories. It can also be used
in fertilizer and explosives. It stops food,
computer parts, and tires from oxidizing. We
can also use it in liquid form, for things such
as preserving cells or chilling equipment such
as equipment for computers or x-rays.
4. Although nitrogen cannot be used in its pure
form, it is still combined with other elements
which makes it useful and is able to be used
successfully in organisms. Nitrogen is a vital
part of life. It plays a very important role for
growth, and it is found in amino acids which
make up proteins that all living things need in
order to grow. Without nitrogen, there would
be no amino acids. This means that there
would be no DNA, and without DNA, there
would be no you or I, animals, plants or any
living thing.
