Answer:
2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.
Explanation:
Cloning has the potential to  significantly benefit a great many  people, so it should not be  considered immoral or risky is refers as scientific observation.
A scientist thinks that he might  find serious inconsistencies in the  fossil record if he conducts an  excavation in a new location is refers scientific explanation because explanation is needed for it.
The rocks present in western Africa  and eastern South America formed  at the same place and at the  same time is scientific observation because the scientists takes the data.
Even if modern organisms are  found in ancient portions of the  fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.
The cloning of organisms is an  exciting area of study, and more  resources should be be devoted  to it so it is refers as scientific explanation.
The age, type, and composition of  ancient rocks in western Africa are  nearly identical to the age, type,  and composition of rocks in  eastern South America is scientific observation which is taken by the scientist through research.

Answer:
The correct answer will be option-E
Explanation:
Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.
To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.  
In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.
Thus, option-E is the correct answer.
