Answer:

B. Multiple origins of replication are activated per chromosome.

Explanation:

DNA replication runs in 2 directions (bidirectional), starting at the origin of replication an moving in both directions from that point. A eukaryotic chromosome may be replicating at many points along its length at any one time.

DNA is always copied in a 5´ ⇒ 3´ direction, this makes the lagging strand to be synthesized discontinuously as short okazaki fragments.

The whole process happens at the same time in both strands in a replication fork. DNA may have different replication forks at the same time to speed up the process.

Which term best describes the systems in an animal's body?
umka21 [38]

Answer:

B. interconnected

Explanation:

All the systems in our bodies (humans are indeed animals) are connected with each other to create a functional being. The blood flows throughout the body, providing nutrients; the bones support the structure and protect the heart and lungs. They work together.

Why not A: The systems are all completely necessary. There's nothing extraneous in our bodies, because extraneous stuff takes up energy, and our biology is incredibly economical.

Why not B: They're not interchangeable. How would you like your bones to turn to blood? Uh-huh.

Why not D: They interact with each other consistently, so they're not separate or segregated.
