Nitrogen and phosphorus pollution in the chesapeake bay causes phytoplankton numbers to increase, which ultimately leads to the process called nitrogen and phosphorus pollution in the chesapeake bay causes phytoplankton numbers to increase, which ultimately leads to the process called carbon fixation eutrophication nitrogen fixation photosynthesis

Nitrogen and phosphorus pollution which causes the increase in population of phytoplanktons lead to the process called euthrophication.

Explanation:

Eutrophication occurs when there is excessive level of phosphorus and nitrogen in the water that leads to the increase in population of phytoplanktons  or algal blooms. Algal blooms has a negative effect to the quality of water for it creates an environment suited for the growth of bacteria and thereby decreasing the supply of oxygen in water. This leads to death of fishes and aquatic life.

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.
