Answer:
The most appropriate explanation would be the presence of two types of melanin in hairs.
In human hairs, two types of melanin are present: eumelanin and pheomelanin.
Eumelanin determines the darkness of the hairs, that is, it would determine if the hairs of a person would be black or brown.
Pheomelanin is responsible for orange or red colors of the hairs. In addition, on breaking down, it provides the hairs with colors like red, orange, yellow and white (complete breakdown of pheomelanin).

Answer:
Hershey and Chase experiment confirms that DNA is the genetic material of the living organism, not the RNA or protein. They also got a noble prize for this discovery.
Hershey and Chase use the radioactive sulfur to label the proteins and distinguish them from the DNA because DNA do not contain sulfur. The radioactive label phosphorus was used to label the DNA as phosphorus is specific to DNA as they wants to know exactly the genetic material. They do not use the radioactive carbon and nitrogen because both carbon and nitrogen are present in DNA and RNA. This labeling may produce confused result as it label both DNA as well as protein. The result o radioactive phosphorus and sulfur determines that DNA is the genetic material of the organism.
