<span>Organic Chemistry is so important in the study of Biology because most reactions in Biology are organic reactions. Organic chemistry is the study of structure, properties, and reactions of organic compounds</span>
Answer:
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
<span>It releases ONE H2O to join TWO monomers.
So, when third monomer joins, 2nd H2O will release.
When 4th monomer join, 3rd H2O will release.
...
....
.... and so on.
When the 20th monomer join, 19th H2O will release.
Means in total of 19 water molecule releases</span>
