<span>The sun's
energy is the primary source of energy for all surface phenomena and life
on Earth. Combined with the material of the Earth (including the molecules
held close by the Earth's gravitational force called the atmosphere),
this energy provides for the immense diversity of life forms that are
found on the Earth. We will now look in detail at solar energy and its
interplay with the constituents of the Earth's atmosphere. </span>

<h3><u>Explanation</u>:</h3>
Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.
This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.
