B. Defecation is a process that uses a lot of water. To compensate for this the large intestine absorbs water back into the body before having waste leave the body.
<span>Studying the gross anatomy of a cadaver can show an individual the total physiology of a human. By dissecting a cadaver or deceased human, you can study the nervous and cardiovascular system as well as the organs and other internal tissues. For example, muscle origin and insertions on bone, blood supply to the muscle and nervous stimulation of the muscle can be studied. Other areas that can be seen are the location of major organs in the thorax and the blood supply to each of them. The discovery of how the cadaver died can also bee seen during the dissection in many cases.</span>
Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.
