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.

Explanation:
Before domestication of animals, these animals were wild and early humans used to hunt for food. The hunting process was not always successful and took a lot of energy from the body. Domestication of these animals made food available and other conveniences. An example is cows that emanated from the domestication of wild aurochs. They provided the milk and meat for humans and also labored in the farm in the cultivation of domesticated plants.
