Answer:
The correct answer is- phosphorus and sulfur
Explanation:
Hershey and Chase used radioactive phosphorus and sulfur to label T2 bacteriophage. Then they infected E.coli with these bacteriophage labeled with radioactive phosphorus and sulfur.
After infection, they centrifuge the cell and found that radioactive phosphorus is present in the bottom and radioactive sulfur in supernatant . As sulfur is mostly the part of protein not DNA and is found in supernatant and phosphorus is mostly present in DNA not protein which was found in cell debris, therefore, it was proved that DNA is the genetic material.
<span>Demoralisation is defined as the act of reducing another's confidence and hope, or discouraging and disheartening someone's optimism. This will cause the individual/s to lose faith in the future. The next question then is how does one aid in fighting demoralisation. One is to avoid focusing on the negative stuff. Another is, one could also keep a journal of self-talk. Self-talking is also important because as a human being it is but normal to constantly talk to yourself or you have that inner monologue with yourself. It is that internal dialogue with yourself which can greatly affect your self-esteem as well as your confidence. When one is positively talking to oneself, one can also positively see good things in his or her life and about himself/herself. This is that voice within oneself that makes you look at the bright side of things. When one does these, demoralisation will surely be out of the topic.</span>
