Which of the following fertilizers does not replenish nitrogen in the soil?

biology air and atmosphere natural cycles and resources constituents of air medicinal use of microorganism component of air - nitrogen

  1. CAN

  2. Urea

  3. Superphosphate lime

  4. Ammonium phosphate

Show answer
Correct Option: C
Explanation:

Phosphate rock is too insoluble for direct use, and is commonly treated with sulfuric acid to make a mixture of calcium sulfate and the more soluble calcium hydrogen phosphate, called superphosphate.The use of superphosphate usually supplies adequate calcium. 

Nitrogen fixation means:

biology air and atmosphere natural cycles and resources constituents of air medicinal use of microorganism component of air - nitrogen

  1. manufacture of nitrogen

  2. liquefication of nitrogen

  3. conversion of nitrogen into nitric acid

  4. conversion of atmospheric nitrogen into useful compounds

  5. mixing of nitrogen with other elements

Show answer
Correct Option: D
Explanation:

Nitrogen fixation is a process in which nitrogen(N2) in the atmosphere is converted into ammonia (NH3) and useful compounds. Atmospheric nitrogen or molecular dinitrogen (N2) is relatively inert: it does not easily react with other chemicals to form new compounds.

So the answer is D.

Which of the following two diseases together are referred to as chronic obstructive lung disease (COLD) or chronic obstructive airways disease?

common respiratory diseases respiratory disorders respiratory system respiratory system of human biology

  1. Acute bronchitis and chronic bronchitis

  2. Chronic bronchitis and emphysema

  3. Tuberculosis and emphysema

  4. Tuberculosis and chronic bronchitis

Show answer
Correct Option: B
Explanation:

  1. Chronic bronchitis is a disease caused by the inflammation of bronchitis which secretes mucous leads to coughing and breathing difficulty and commonly observed in smokers.
  2. Emphysema is a disease in which alveolar sacs get damage which results in the deficiency in the amount of oxygen required by the body and its common cause is also smoking.
When these two diseases found together in a patient it is referred to as chronic obstructive lung disease (COLD) or chronic obstructive airways disease.
So the correct option is 'Chronic bronchitis and emphysema'.

Which of the following disease affects alveoli of lungs?

  1. Pneumonia

  2. Emphysema

  3. Asthma

  4. $(1)$ and $(2)$

Show answer
Correct Option: A

Inflammation of the lung covering causing severe chest pain is

common respiratory diseases respiratory disorders respiratory system respiratory system of human biology

  1. Emphysema

  2. Pleurisy

  3. Asphyxia

  4. Hypoxia

Show answer
Correct Option: B
Explanation:

Pleurisy involves inflammation of the tissue layers (pleura) lining the lungs and inner chest wall. Pleurisy is often associated with the accumulation of fluid between the two layers of pleura, known as pleural effusion. Symptoms of pleurisy include pain in the chest, which is aggravated by breathing in, shortness of breath, and local tenderness. The diagnosis of pleurisy is made by the characteristic chest pain and physical findings on examination of the chest. The pleural accumulation of fluid (pleural effusion) can be seen by imaging studies.

Chemicals in cigarette smoke lead to the breakdown of the walls of the alveoli. What is the name given to this disease ?

common respiratory diseases respiratory disorders respiratory system respiratory system of human biology

  1. Bronchitis

  2. emphysema

  3. coronary heart disease

  4. lung cancer

Show answer
Correct Option: A
Explanation:

Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs. Symptoms include coughing up mucus, wheezing, shortness of breath, and chest discomfort, such mainly occurs due to large consumption of smoke which leads to the breakdown of the walls of alveoli. 

So, 'the correct option is Bronchitis'.
