Answer:
Elastomeric
Explanation:
An elastomer is a polymer whose main characteristic is elasticity and can even recover its shape after being deformed
The chemical composition of an elastomer is the grouping of thousands of molecules called monomers, which join together forming huge chains. These large chains of polymers are those that give elasticity since they are flexible and are intertwined in a very messy way.
When an elastomer is stretched, its molecules align, allowing many times to take a crystalline appearance. However, upon releasing the tension, it immediately returns to its original state of elastic disorder. The above distinguishes elastomers from plastic polymers.
I think the correct answer from the choices listed above is option A. One way in which bacteria differs from humans is that bac<span>teria are single-celled while humans contains a lot of cells. Bacteria can be found microscopically while humans are not. Hope this answers the question.</span>
The chemical group is the methyl group (-CH3).
