I think that the healthcare common procedure coding system was originally developed for use in coding services, such as durable medical equipment, for Medicare patients. The HCPS is a set of health care procedure codes based on the American Medical Association's Current procedural Terminology.
28. <u>Answer</u>: All mutations do not affect the organisms due to the following reasons:-
1. The DNA consists of both coding and non coding regions. The coding regions are known as exons and non coding regions are called as introns. The <em>non coding regions </em>do not make up the protein. Thus, if the mutations occur in non coding regions they do not affect the organism.
2. There are some mutations that result in the change of the codon but the new codon formed codes for the same amino as the previous one. This is possible because of the degeneracy of genetic code. For eg, AAA codes for lysine, however if the mutation changes this code to AAU then this also codes for lysine. Such mutations are called as <em>silent</em> mutations.
3. There are some mutations which result in the change in amino acid however the new amino acid formed is similar to the previous one in its properties for e.g leucine and isoleucine. Such mutations are called as <em>neutral</em> mutations and they do not affect the organism
29. <u>Answer</u>: 1. The process of mitosis results in the formation of <em>two diploid cells</em> whereas meiosis results in the formation of <em>4 haploid cells.</em>
2. The process of mitosis takes place to produce copies of the <em>body cells </em>whereas the process of meiosis takes place to produce the <em>gametes</em>.
<u>Explanation</u>:-
- <u>Mitosis</u> is a process in which a cell undergoes a single round of division to produce two identical copies of itself . It occurs in 4 phases Prophase, metaphase, anaphase and telophase. This process occurs in the body cells.
- <u>Meiosis</u> is a process in which a cell undergoes two rounds of cell division to produce 4 copies of haploid cells from a single diploid cell. This process takes place for the formation of gametes.
29. <u>Answer</u>:
<em>Pros</em>
1. Genetic engineering helps us to tackle several diseases. There are many diseases which are caused due to genetic mutations. Genetic engineering helps us to rectify these mutations and hence combat such diseases.
2. Genetic engineering helps us to produce new foods which can withstand adverse conditions such as high/low temperatures, low rainfall, are disease and pest resistant etc. This, genetic engineering helps to significantly improve crop production.
<em>Cons</em>
1. Genetic engineering leads to a decrease in genetic diversity.
2. It can lead to a decrease in the nutritional value of food as genetic engineering often causes an accelerated growth of animals and hence, the nutritional valie of poultry foods is compromised.
Answer:
Hepatitis A infection can be prevented by getting vaccine or immune globulin soon after coming into contact with the virus. Persons who have recently been exposed to HAV should get immune globulin or vaccine as soon as possible, but not more than 2 weeks after the last exposure.
Explanation:
You can take steps to reduce the risk of passing hepatitis A to others.
Avoid sexual activity. Avoid all sexual activity if you have hepatitis A.
Wash your hands thoroughly after using the toilet and changing diapers.
Don't prepare food for others while you're actively infected.
Answer:
Thymine, which is often abbreviated to T or Thy, can also be referred to as 5-methyluracil. It is one of the pyrimidine bases found in the nucleic acid of DNA, along with adenine, guanine and cytosine (A, G and C). These bases are the building blocks of DNA and life form on earth.
