A scientist hypothesized that oxygen atoms from both carbon dioxide and water are used to make glucose during photosynthesis. However, experimental results using oxygen isotopes showed that all of the oxygen from the water ended up in the oxygen molecules that were produced. None of the oxygen from water was found in glucose. What should the scientist do to best gain scientific understanding of this topic?
Analyze the results, and change the experimental methods to retest the hypotheses in a different way.
Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.
Analyze the procedural errors that took place in the experiment, and summarize these in a conclusion statement.
Repeat the experiment and adjust new data to support the original hypothesis.

Discard the faulty results that do not support the original hypothesis, and repeat the experiment using the same methods.

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.

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.
