An endoscopy that is undertaken to the level of the mid transverse colon would be coded as a Colonoscopy. A colonoscopy is a test using a thin flexible tube called a colonoscope to look closer at the colon; by looking closely at the inner lining of the large intestine, being the rectum and colon, doctors are able to further identify ulcers, tumors, bleeding, and inflammation, which other tests would not be able to discover as accurately. Hope that helps.
This might be useful cause it’s useful and it’s also useful and I hope this is useful you’re welcome for being useful :)
Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.
Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Therefore, the correct option is E.
