Ascientist is studying the effect on human health of bacteria that live in the human intestine. in her study, she found that the bacteria actually the body’s immune response. to develop scientific consensus about her idea, the scientist should
contact a local reporter to share her ideas.
publish her results in a peer-reviewed journal.
advise other scientists that her experiment does not require replication.
avoid sharing her research methods to see if other scientists obtain the same results on their own.

The hershey and chase experiments involved the preparation of two different types of radioactively labeled phage. which of the following best explains why two preparations were required? a. the bacteriophage used in the experiments was a t2 phage. b. it was necessary that each of the two phage components, dna and protein, be identifiable upon recovery at the end of the experiment. c. each scientist had his own method for labeling phage, so each conducted the same experiment using a different isotope. d. establishing the identity of the genetic material required observation of two phage generations.
