A. Earthquakes is the answer
He got it right i just took that test
Answer: Earth is rotating while the moon spinning around it. It takes 24hrs to make a full rotation or a full day.
From the polymers listed, the ones which are found in natural sources are: protein, cotton and silk.
A polymer is a large molecule composed of many repeated subunits. Many small molecules (monomers) are bound by chemical reactions, called polymerization, and form the polymers. Polymers are widely used in many applications and they can either be synthetic or naturally occurring biopolymers. In the provided list, polypropylene, polyvinyl chloride and nylon are synthetic polymers. Polypropylene and nylon are thermoplastic polymers, and polyvinyl chloride (vinyl) is a plastic polymer. On the other hand, proteins are naturally occurring polymers produced by many amino acids. Cotton is formed by repeating units of cellobiose and it is a naturally occurring cellulose polymer. Finally, silk is a polypeptide and a linear fibroin polymer.
