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.
Answer I think it’s liquid soap
Answer:
The most inclusive level of organization is called the Biosphere.
Explanation:
The biological level of organization is organized from the simplest(least inclusive) to the most complex(most inclusive)
The Atom is the simplest unit. Two or more atoms will form a molecule.
The molecules come together to form a cell which is the basic functional unit of life. Cells come together to form tissues then organs and the organ system. Together they make an organism
Populations is formed by a group of the same organisms living in the same area.
Different populations will form a community. The communities together with the environment they live in form an Ecosystem.
Lastly, The Biosphere is the most inclusive and encompasses all ecosystems on Earth
