Which of the following matches a human action with its impact? (6 points) construction of bridges : water pollution construction of dams : decrease in carbon dioxide level use of fertilizers : increase in population of aquatic animals decrease in honeybee population : increase in plant population

Construction of bridges : Water pollution

Explanation: Bridges are built over water, correct? So you can only assume that debris is going into the water when being constructed.

Also, you can terminate the other answers immediately

1. Decrease in honeybee population : Increase in plant population

That would decrease the plant population because honeybees are needed in order for plants to survive.

2. Use of fertilizers : Increase in population of aquatic animals

This would decrease the population of aquatic animals because fertilizers are toxic, and runoff from farms can go into water and harm aquatic animals.

3. Construction of dams : Decrease in carbon dioxide level

Construction of dams don't decrease carbon dioxide levels. If anything, it'd cause pollution.  

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.
