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.
<span>When you put the cells in a salt solution you are placing the cells into a hypertonic solution. That means the solute concentration outside the cell is higher than the solute concentration inside the cell. You should know from your own studies that water will move from areas of high water concentration to areas of low water concentration. A hight solute concentration means there is low water concentration. That means that the water will move from the onion cell and out into the hypertonic solution and the onion cell will shrivel up.</span>
DNA is an example of a complex biological polymer called a nuclei acid. Nucleic acids are made up of many smaller sub units called nucleotides. The components of a DNA nucleotide are deoxyribose, phosphate group, nitrogen group. There are four possible bases in a DNA molecules which includes adenine, cytosine, guanine and tymine.
