  • a deoxyribose sugar
  • a single nitrogen-containing base

<h3>How is the structure of DNA formed?</h3>

DNA is a biological molecule that stores genetic information in living cells.

The structure of these DNA molecule was built and proposed by a duo scientist named James Watson and Francis Crick in the 1950s.

However, they determined three important features of the DNA molecule and are as follows:

  1. a phosphate group
  2. a deoxyribose sugar
  3. a single nitrogen-containing base

Answer:

need to be done with plenty of observation to avoid infection.

Explanation:

This technique is quite delicate because the main risk is infection. Some of the main risks are neuromuscular disease, sedation or neurological illness.

Another risk is that by passing the time, there is a difficult in respiratory, in this case, the main risk is directly to the heart, with some stoke, due to the high concentration of carbon dioxide due to the low exchange among oxygen and CO2.

Some of the indications are:

a.- Coarse crackles auscultated over trachea.

b.- Increase the respiratory pressure.

c.- Decrease tidal volume.

d.- Check the levels of oxygen in blood as in arteries.

e.- Check that patients can generate a cough.

Hope this info is useful.

Answer:

The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.

Explanation:

Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.

Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.

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.
