Answer:
Option B, can be used to either sterilize or pasteurize, depending on the dose of radiation
Explanation:
Sterilization by radiation has started since 1895. However, commercial food irradiation plant was installed at Stuttgart, Germany in 1958. In general gamma radiation is used for sterilization purposes which disrupts the sub-atomic particles involved in the formation of the microorganism at an early stage by damaging their genetic material such as DNA or RNA with in their cells. Once the genetic material i.e DNA or RNA is damaged, the cell dies automatically.
Hence, option B is correct
Answer:
A) all answers are correct
Explanation:
Wind belts, tropical easterlies
, and polar easterlies are all examples of unequal heating of the earth by the sun and the earth's rotation, because they distribute heat or cold unevenly based on the sun heat and the earth's rotation.
Griffith experiment
Griffith used two types of bacteria in his experiment
1. R-type: it was non-virulent and cause no disease in mice
2. S-type: It was virulent and cause disease in mice which lead to death.
However when heat killed S-type was applied no disease was occurred in mice. Then he mixed heat killed S-type and live R-type and injected it into mice. He was expecting that no disease will be caused in mice.
Results
However, mice was died.
Conclusion
He was confused from this experiment. But later it was confirmed by other scientists that DNA from heat killed S-type was shifted to R-type. the progeny which formed from this transfer of DNA were virulent and cause the death of mice.
significance
It was concluded from this experiment that DNA is a hereditary material which transfer characters from parents to offspring.
N61. 21 is a specific ICD-10-CM code that can be used to show a diagnosis for refund goals.
<h3>What is in ICD-10-CM?</h3>
The medical field has different types of manuals. This is called a tabular list in the ICD-10-CM. It is used for accurate ICD-10-CM code assignment as it can be used to identify poisonings and external causes of high/bad effects.
The second part of the ICD-10-CM is known as the Tabular List of Diseases and Injuries. There are 21 chapters are there in the tabular list.
Note that all ICD-10-CM codes start with a letter, all code stages are in alphabetical order based on the first characters.
