<span>Sodium chloride is an example of an ionic compound. An ionic compound is composed of a positively charged cation and a negatively charged anion that are held together by their attractive forces. For table salt, Sodium chloride, Sodium is the cation and Chloride is the anion. </span>
Answer is (E) : Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Let me explain you why. Hershey and Chase conducted their experiment to show what is the genetic material that passes from one generation to another generation. Is it protein or DNA? For explaining this, they allowed the virus to grow in the presence of two different radio active elements.
In one set they grew viruses in the presence of P-32 radio-active element
In another set they grew viruses in the presence of S-35 radio active element.
The reason why they choose these two radio-active element was, phosphorus is present in DNA but not in proteins and similarly sulphur is found in proteins but not DNA.
These viruses were allowed to infect bacteria and the later was observed to be radio-actively labelled with P-32 but not S-35. This clearly showed that DNA is the genetic material which was passed from virus to bacteria.
Now if you choose Nitrogen for labeling, it won't help you in getting any conclusion since nitrogen is present in both proteins and DNA.

I believe that would be Golgi Apparatus and the plasma Membrane most likely hope this helps.
Answer:
They are in organic
Explanation:
Vitamins are organic compounds derived from plants or animals that are needed in the body at small quantities.
They help in the body's metabolism since they enhance enzymatic activities and can act as co-factors.
They are essential for good health such as vitamin A helps in improving eye sight.
Lack of certain essential vitamins can lead to disease ,lack of vitamin D can lead to Rickets.
