Answer:

Hershey and Chase experiment confirms that DNA is the genetic material of the living organism, not the RNA or protein. They also got a noble prize for this discovery.

Hershey and Chase use the radioactive sulfur to label the proteins and distinguish them from the DNA because DNA do not contain sulfur. The radioactive label phosphorus was used to label the DNA as phosphorus is specific to DNA as they wants to know exactly the genetic material. They do not use the radioactive carbon and nitrogen because both carbon and nitrogen are present in DNA and RNA. This labeling may produce confused result as it label both DNA as well as protein. The result o radioactive phosphorus and sulfur determines that DNA is the genetic material of the organism.

The mass of a star can be determined by studying _____.
Lilit [14]

<u>Answer</u>:

The mass of a star can be determined by studying binary star systems.

<u>Explanation</u>:

In this system it consists of two stars, revolving round the same bary-centre. The systems having two or may say more than two are called as the multiple star system. This zone is also a habitable zone, here the water exists in the liquid form. We could have sometime seen the two stars together. They are also very capable of strengthening the terrestrial planets inside the stable orbital ranges. They have generally two orbits like P-type as well as circumbinary.

A qualified genetics counselor is working with a child who has been diagnosed with fragile x syndrome. after extensive research
Alenkinab [10]

Answer:

CPT® Index - 96040

icd-10-cm code - Q99.2

Explanation:

Here in this case the diagnosis came out with fragility in X chromosome. This is some thing related with medical genetics. Hence, the CPT® Index for this scenario would be 96040. As per the American Medical Association, CPT® Index 96040 cover cases that fall into the category of “Medical Genetics and Genetic Counseling Services” which also involves counseling either with the patient or family for 30 minutes. The icd-10-cm code – Q99.2 deals with the problems associated with genetic abnormality

Hence, the answer is

CPT® Index - 96040

icd-10-cm code - Q99.2
