When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
In order to survive the winter, monarch butterflies "migrate to warmer areas".
<u>Option: B</u>
<u>Explanation:</u>
- The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
- This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
- Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
- If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
