Answer:
As DNA contain phosphorus in its structure in large amount, therefore, Harshey and Chase labeled DNA with radioactive phosphorus and because protein contains some amino acids which have sulfur so they labeled T2 bacteriophage protein with sulfur.
So after that they infected E.coli bacteria with radioactively labeled phages and after centrifugation, they have found that pellet which contains cells is showing the presence of radioactive phosphorus and supernatant which have T2 phage capsid protein showing the presence of radioactive sulfur.
Therefore by labeling viral protein and viral DNA they found that DNA is the genetic material not protein.

Answer:
Well the model above is showing all the planets in order from how close or far away they are from the sun and it also seems to show the scale of each planet compared to another.
Explanation:
As for the Evidence or why it is important to know this is because the scale and location of the planet to the sun directly effects everything about the planet, its Atmosphere, tempterue and rotaion. And the more we learn about all plants we can better underatand our own geological past behavior of its Atmostohere and futute clamatic trends.
<span>Since we are not able to get energy directly from the food we eat, a particular process needs to take place that converts molecules to Adenosine triphosphate, also known as ATP. This requires that the food first be broken down by being digested. As digestion takes place, the body uses the small molecules to make ATP.</span>
