<span>The first organic compound is Carbohydrates. Most organisms
use is as a primary fuel or their main energy source. They make up cell
structures, and they're also used as stored energy in plants. Second is Lipids.
If we have any other energy left over in our bodies, we typically will store
that as lipids, which a lot of people think of as fats. It also makes up the
cell membrane, and coats the leaves of plants to make them waterproof and also
protect them from the elements. Third type are proteins. One use of proteins
are chemical messengers or hormones. Proteins are useful for receptors and
transport channels in order to help things move in and out of the cell. They
also help to control and regulate chemical reactions. Another use is for cell
structures, like your hair. the last one is for immunity. The fourth and last
is Nucleic Acids. There are two main uses in organisms for nucleic acids. The
first one is for protein synthesis. The other use is for our hereditary
information or how we pass our traits to our offspring.</span>
Answer:
EDTA is a chelating agent used to preserve samples for DNA extraction and as an anticoagulant
Explanation:
Ethylenediaminetetraacetic acid (EDTA) is a well-known chelating agent that binds metal ions (iron and calcium ions). In police cases, EDTA can be used for DNA extraction since this agent chelates metal ions in DNase enzymes which are contained in the samples, thereby reducing their activity and preserving DNA samples for a long time. Moreover, EDTA is also used as an anticoagulant for blood cells, which allows preserving the cellular components and the morphology of blood samples.
