Because of the connection between greenhouse gases and climate change, there has been a concerted effort to reduce greenhouse gas emissions. How does this second graph, published by the EPA, support the growing trend in reducing these emissions? A) The second graph shows that the electricity generation sector has done a good job at substantially reducing the emission of all greenhouse gases. B) The top graph shows the greatest fluctuations in carbon dioxide. The second graph shows that there has been little change if any in the emissions by each sector. C) It does not support the idea that there is a great reduction in any sector of greenhouse gases. The lines in the second graph remain reasonably flat throughout the sectors in the graph. D) Of greatest concern is carbon dioxide emissions as seen in the top graph. In the second graph, the electricity generation and transportation sectors have reduced the emissions slightly.

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.
