First equate the discounted(sale price) $46.75 to 100%. If
$46.75=100%,what about 90%since it was discounted by 10%

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 D.
From the scientific research conducted so far, we know that in the early Earth's history the atmosphere lacked oxygen and was mostly filled with other gases like methane. The increase in oxygen levels happened when the plants started producing oxygen as a byproduct of the process of photosynthesis.
The research so far also shows that the RNA was present before the DNA and that the microspheres might have been essential to the development of life on Earth.
