The brain of a teenager is different from that of an adult. the frontal lobes are not fully mature until the mid-twenties and the reward centers tend to have an exaggerated response to larger rewards compared to small rewards. this biological reality may affect teenage decision-making. consider the debate about increasing the age at which teens can obtain a driver’s license. do you think this is a good idea or a bad idea? why?

It is a good idea.

Explanation:

Note that, because the teenager front lobe is not fully mature, they can only access it more slowly. This is because the nerve cells connecting their frontal lobe with the rest of their brain are slugging.

Also, they lack myelin present in the area in adult. This myelin acts like an insulation on electrical wire. Lack of myelin or having a thin myelin leads to inefficient communication between one part of the brain and another.

The teenagers are self centered, rude and selfish. This is because they have not entirely reach the stage of thinking about the effect of their behavior on other people.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
