The sulphur would lable the capsule and the phosphorous the nucleic acid.
<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.

Answer:
b. Segments can become specialized on a particular function
Explanation:
Segmentation conditions virtually every aspect of the structure and functioning of animals with a consecutive body. Generally speaking, we can say that the main advantage of segmentation is that each segment can become specialized in a specific function.
One of its advantages is related to locomotion and comes, on the one hand, from the fact that the volume of celiac fluid remains constant in each compartment, acting as an antagonistic force against which muscles can act and, on the other, from the possibility of independently control each segment
. This allows the peristaltic movement (circular muscle contraction wave followed by longitudinal muscle contraction) to be localized and involve only those muscles that are strictly necessary, making the movement's energy needs considerably more profitable.
The compartmentalization of the body led to the repetition of structures, namely excretory, nervous and circulatory in each segment. This can be seen as another advantage of segmentation as it may lessen the impact of damage to the animal's body; Undamaged segments can maintain their normal functions and thus increase the likelihood that the animal will overcome the damage sustained.
Another advantage is that segmentation allows modification of certain portions of the body to perform specialized functions such as feeding, locomotion and reproduction.
