The answer is A .
PCR stands for Polymerase Chain Reaction. It is a method to analyze a short sequence of DNA or RNA and is used to reproduce (amplify) selected sections of the nucleic acid. Untold numbers of copies can be made of the DNA in just a few hours.
PCR amplifies the regions of DNA that it targets and can therefore be used to analyze extremely small amounts of sample. This is often critical for forensic analysis, when only a trace amount of DNA is available as evidence.

Answer:
Plastics are non-corrosive in nature because they do not react with air, water or other substances. They do not get corroded even if they come in contact with strong chemicals. This is because of their non-reactive nature with most materials. For example, the cleansing chemicals that we use at home are stored in plastic bottles, instead of metal containers. I know its late but I still hope it helped. :)
Answer:
Peer-reviewed
Explanation:
If a scientific report is peer-reviewed it means that the contents of the report are corroborated by other scientists hence the veracity of the information is high and is very reliable. The best scientific reports clearly describe the experiments that were conducted to culminate to a particular scientific conclusion. The experiment is able to be replicated by another scientist and if the same results are achieved then the results are corroborated and the report positively reviewed.
