Ethics plays an important role in conducting of research. While the individual researcher is responsible for his/her ethical practice, any research sponsored by an organization, university, or government program has a review process guided by a code of ethics.  Besides the code of ethics, the Institutional Review Board (IRB) plays an important role in monitoring research.  Your task in this discussion is to examine the origins of the IRB and analyze how the Review Board guides or monitors research.  In your 250-300 word post answer the following three questions:
