Answer:
<em><u>A. Neither the subjects nor the researchers can bias the results.</u></em>
Explanation:
As described, a double- blind study is one in which the researcher and his study does not know the person receiving the actual treatment.
Researchers can be bias in their studies as they seek to establish and fine tune results in the way the best favors them. A double-blind study helps to bridge this gap to prevent bias that might be introduced into an experimental set up or while interpreting results.
Despite longstanding assumptions by marine biologists, very young sea turtles travel by swimming, not just drifting.
<u>Explanation:</u>
The movement of sea turtles will be always slower in nature. This is because they are herbivores. They feed on plants and they will be available for them in larger quantity. Hence, they move slowly because they are not in a need to run behind their food faster.
Drifting refers to the movement due to force or pressure that may be caused by wind. Swimming refers to a movement where the entire body movement is essential for moving. From the investigation by the researchers given in the example, we can conclude that despite of longstanding assumptions by marine biologists, very young sea turtles travel by swimming, not just drifting.
Answer: With gene therapy
Explanation:
Manipulation of DNA or RNA is used to treat disease with gene therapy. This type of therapy is introducing genetic material into cells because it should compensate for abnormal genes or it should also make a beneficial protein.
Gene therapy is able in some cases to introduce a normal copy of the gene and after that, it can restore the function of the protein.
