Define the term polymer.
Your Answer:
Polymers are large molecules made by repetitive linking of smaller units known as monomers.
Answer:
Polymers are large molecules made by repetitive linking of smaller units known as monomers. The terms polymer and monomer are derived from the Greek roots poly (many), mono (one), and meros (part).Not yet graded / 0 pts Question 1 Not yet graded / 0 pts Question 2

What is a macromolecule?
Your Answer:
A macromolecule is a very large molecule composed of thousands of covalently bonded atoms. Polymers can also be classified as either natural or synthetic.Not yet graded / 0 pts Question 3
Name and describe the two main classifications of polymers.
Your Answer:
Chain-growth polymers (also known as addition polymers) are made by the addition of one monomer unit to another in a repetitive manner.Monomers for addition polymers usually contain a multiple bond (frequently a C=C) to which a reactive species can be added.Step-growth polymers (also known as condensation polymers) are formed by the reaction between two different functional groups on different monomer molecules, with the accompanying loss of some small molecule (typically water).
Answer:
Polymers can be classified as either natural or synthetic. Natural polymers include rubber, carbohydrates like starch or cellulose, proteins, and nucleic acids (DNA/RNA). The biologically relevant natural polymers are sometimes called biopolymers. Synthetic polymers are created by scientists in a lab (not formed in nature) for specific purposes. Synthetic polymers are generally known by the generic term “plastics”
