Polymerization and the break down of a polymer are two opposite reactions. What role does a water molecule play in both of them?

Answers

Answer 1

Answer: A polymer is a large molecule made up of smaller molecules called monomers. The process of monomers joining each other to create a polymer is called polymerization. Water plays a role in condensation polymerization. In this reaction a hydrogen from one monomer will connect with the hydroxyl functional group of another monomer. The two join and water is formed. the water breaks off, leaving the remaining functional groups of the monomers able to be joined together.
Hydrolysis is the opposite reaction where water is added to the polymer. The hydrogen (H) and hydroxide (-OH) react with the functional groups that formed the bond and as a result break apart the polymer.

The _____ tube brings a mature ovum to the uterus. fallopian ovarian Cowper

Answers

The correct answer is fallopian tube.

The fallopian tube, also known as uterine tube or oviduct, carries the egg from ovary to the uterus.

The fallopian tube has finger-like projections or branches called fimbriae which reach out into the pelvic cavity and pick up an egg that has been released from the ovary.

The egg is tenderly brought into the fallopian tube where it begins to travel to the uterus.

The fallopian tube also serves as the location where fertilization of the egg by a sperm cell occurs.
