The question is somewhat confusing. I would choose "none of the above" because none of the choices are blood vessels. However, the heart is the pump that moves blood through the network of blood vessels that distribute and collect materials throughout the body.

Could you be more specific? Through each consumption of an organism, the energy level decreases about 10%. For example, a producer has more energy than a secondary consumer.

The correct answer is: B. the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction.
The replication of DNA molecule or DNA synthesis is done by an enzyme- DNA polymerase that can work only in the 5' to 3' direction.
After helicase unzips the double-stranded DNA for replication, a replication fork is formed. The leading strand is synthesized in the same direction as the movement of the replication fork so it can occur continuously: the primase generates short strands of RNA-primers that bind to the single-stranded DNA to initiate DNA synthesis. On the other hand, the lagging strand is synthesized in the opposite direction comparing to the movement of replication fork and its replication is discontinuous, with short Okazaki fragments being formed and later linked together.
