Answer:
The correct answer will be option-A
Explanation:
The transport of the molecules between cells and a cell and its surrounding is very important to survive.
A cell has evolved two ways to transport the molecules which are passive and active movement or transport.
The passive movement is the movement of the molecules across the membrane depending on the concentration gradient without using any source of energy which is utilized in active transport.
In the given question, osmosis is the process which can be considered passive movement as it transports the water down the concentration gradient without using any source of water.
Thus, osmosis is the correct answer.
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.
