In vitro cultivation of He la cells was proved to be successful with millions of her cells cultured in the laboratory which is still exists.

The He la cells contaminate other human cell lines,It was thrown a light on culture contamination  issues in many scientific field. The pros and cons of He la cells are given in a table format which is attached.

Answer:

Pros of HeLa cells:

  • HeLa cells are immortal ,easy to maintain and can be kept alive.
  • HeLa cells easily contaminate cell lines and thus can be  incorporated easily into target tissues.

Cons of HeLa cell:

  • The HeLa cells can easily contaminate cell lines and a lack of regular monitoring leads to unwanted contamination of cell lines resulting in wastage.

Explanation:

HeLa cells are immortal cells that are used in scientific and medical research. These were obtained from Henrietta Lacks , a cervical cancer patient. These cells are well known for their immortality, rapid growth and high contamination rate. These were unique cancerous cells that kept on dividing and remained alive easily.

Answer:

1.Carbon dioxide is converted to sugar used for food. - 1. Location- A

2.Carbon trapped in fossil fuels is converted to carbon dioxide. - 2. Location- C

3.Organic carbon is converted to fossil fuels. -3. Location- E

4.Carbon dioxide is converted to carbonates.- 4. Location- D  

5.Sugar is broken down and converted to carbon dioxide.  - 5. Location- F

Explanation

1. Carbon dioxide is converted to sugar used for food: The carbon dioxide is converted into sugars by the process of photosynthesis, which occurs in the green plants. Plants trap carbon dioxide and sunlight from the atmosphere, to synthesize their food.

2. Carbon trapped in fossil fuels is converted to carbon dioxide: The fossil fuel produced deep inside the earth, acquired by the factory. From the factory the carbon dioxide liberated to the atmosphere.

3. Organic carbon is converted to fossil fuels: The organic carbon obtained after the degradation of organic matter is responsible for the synthesis of fossil fuels.

4. Carbon dioxide is converted to carbonates: The carbon dioxide from the atmosphere gets dissolved with water of the water body and termed as carbonic water.

5.Sugar is broken down and converted to carbon dioxide: The glucose or sugar as a source of food in plants gets broken down into carbon dioxide and water by the process of respiration.

Kipish [7]

Answer:

The correct answer is the last statement.

Explanation:

In the mentioned case, the gathering of unsecreted protein has been witnessed in distinct locations, that is, in the endoplasmic reticulum, in the vesicles near the plasma membrane, and in the Golgi complex. Thus, it can be stated that the unsecreted protein will get gathered at a particular location at a particular temperature.  

Hence, the correct statement is that different temperature-sensitive mutations influence different phases of the transport process.
