The leading strand is the daughter strand that has its end pointed toward the replication fork and is therefore synthesized 3'; in a series of segments none of the other answer options is correct. 5'; in a series of segments 3'; continuously 5'; continuously they provide the energy necessary to separate the two strands of dna. they direct the primase where to lay down the primer. none of the answer options is correct. they direct where replication will start. they prevent the two parental strands from coming together again.

The correct answer is 5’; continuously.

Explanation:

The leading strand is the daughter strand that has its 5’ end pointed toward the replication fork and is therefore synthesized continuously. The leading strand goes from 3’ to 5’. It’s called leading because DNA polymerase works properly in that direction, but otherwise it does not work. Therefore, the leading strand can be synthesized continuously and the lagging strand is synthesized in segments.

the answer is "a.) well–developed vascular system."

explanation:

a. by using fur or clothes to trap heat energy near the body
