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.

Insular cortex

The insular cortex is found in the visceral sensory area and receives sensory input from the thalamus to the CNS. They play a role in emotions including self awareness, motor control etc and they also play a part in the regulation of the body's homeostasis.

After some time, many moths mutated and also became darker to blend in when they were on trees to prevent being eaten by predators. In conclusion, the population decreased.
