  1. Lung cancer

  2. Baldness

  3. Colour blindness

  4. None of the above

Show answer
Correct Option: A
Explanation:

Cigarette smoking causes lung cancer by damaging the cells that line the lungs. When we inhale cigarette smoke, which is full of cancer-causing substances (carcinogens), changes in the lung tissue begin almost immediately. At first our body may be able to repair this damage. But with each repeated exposure, normal cells that line our lungs are increasingly damaged. Over time, the damage causes cells to act abnormally and eventually cancer may develop. People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer. The more years a person smokes and the more cigarettes smoked each day, the more risk goes up. Cigarette smoking causes many types of cancer, including cancers of the lung, oesophagus, larynx (voice box), mouth, throat, kidney, bladder, pancreas, stomach, and cervix, as well as acute myeloid leukemia.

  2. Yelllowing of eyes

  3. Lung cancer

  4. None of the above

Show answer
Correct Option: C
Explanation:
In about 80-90% of the deaths that occur due to lung cancer, smoking is the main reason. Cigarette smoke has carcinogens i.e. cancer causing agents. When cigarette smoke is inhaled, changes occur in lung tissue. The cells of lungs are damaged. These cells are repaired by body itself but as more and more cells are damaged and repaired by body, the cells act abnormally and this may result in abnormal and uncontrolled division of cells leading to cancer.
So, the correct answer is 'Lung cancer'.

Heavy smokers are most likely to suffer from

  1. Asthma

  2. Silicosis

  3. Emphysema

  4. Anosmia

  5. Bronchitis

Show answer
Correct Option: C
Explanation:

Emphysema is a progressive, incurable chronic lung infection. The air sacs or the alveoli are destroyed and oxygen uptake is restricted due to the loss of elasticity of lung tissue.
Thus, the correct answer is option (C), 'Emphysema'.

Nicotine acts as a stimulant because it mimics the effect of

  1. Thyroxine

  2. Acetylcholine

  3. Testosterone

  4. Dopamine

Show answer
Correct Option: B
Explanation:

Nicotine is found in the leaves of tobacco. It acts as both stimulant as it mimics the acetylcholine and also as the depressor. It stimulates passage of nerve impulses causes muscles to relax.

  1. It causes cancer.

  2. It causes cardiovascular problems.

  4. All of the above.

Show answer
Correct Option: D
Explanation:
Cigarette-smoking is harmful because
  • It causes cancer.
  • It causes cardiovascular problems.
  • It causes bronchitis.
Cigarettes, cigars, and pipe tobacco are made from dried tobacco leaves, and ingredients are added for flavor and to make smoking more pleasant. The smoke from these products is a complex mixture of chemicals produced by the burning of tobacco and its additives. Tobacco smoke is made up of more than 7,000 chemicals, including over 70 known to cause cancer (carcinogens). Some of these substances cause heart and lung diseases, too, and all of them can be deadly. You might be surprised to know some of the chemicals found in tobacco smoke include:
  • Cyanide
  • Benzene
  • Formaldehyde
  • Methanol (wood alcohol)
  • Acetylene (the fuel used in welding torches)
  • Ammonia
Tobacco smoke also contains tar and the poison gases carbon monoxide and nitrogen oxide. The ingredient that produces the effect people are looking for is nicotine, an addictive drug and one of the harshest chemicals in tobacco smoke.
The tobacco leaves used to make cigarettes and cigars contain radioactive materials; the amount depends on the soil the plants were grown in and fertilizers used. But this means that the smoke contains small amounts of radioactive material, too, which smokers take into their lungs as they inhale. These radioactive particles build up in the lungs, and over time can mean a big dose of radiation. This may be another key factor in smokers getting lung cancer.
