"you see a person in a wheelchair crossing the street with heavy bag of groceries. it looks like she might need some . what would be the most appropriate action to take? "

We should help her

Explanation:

A person on a wheel chair might need help if he is having grocery in his hand. This is because he will need his hand to move the wheels so as to cross the road.

The person might need help in case of crossing road. One must reach the person and ask that whether she needs help or not.

If the person says yes then one should carry the grocery and help the person cross the road.

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.
