Answer:
The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval
Explanation:
Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.
The correct answer is C. Genetic analysis
Explanation:
In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
