Multiple choice biology diseases and immunity pathogen and their mode of transmission classification of microbes infectious diseases

Which of the following is water borne disease?

  1. Malaria

  2. Cholera

  3. Tuberculosis

  4. Both A and B
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cholera is caused by the bacterium Vibrio cholerae. This bacteria is usually found in food or water contaminated by feces of an infected person. This is most likely to happen when sewage water mixes with a source of drinking water. Drinking water after boiling helps to prevent this infection. Thus the correct answer is option B.

Which of the following causes infectious diseases?

  1. Pollutants

  2. Harmful lifestyle

  3. Inheritance

  4. Microorganisms
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pollutants are the harmful oxides or chemicals which degrade the quality of the environment and causes pollution. 

Harmful lifestyle affects the metabolic process of the body and leading to severe diseases and also causes ageing.
Inheritance is the transfer of characters from the parents to offsprings. 
Microorganisms are the small microorganism which are not visible to naked eye and carries the pathogens responsible for infectious disease.
So, the correct answer is option D.

  2. Dengue

  3. Typhoid

  4. Influenza
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rabies is a viral infection that mainly spreads through a bite from an infected animal. It is an RNA virus of the rhabdovirus family.Once inside the nervous system, the virus produces acute inflammatiom of the brain. Coma and death soon follows. Encephelitus Rabies:This occurs in 80% of human cases. The person is more likely to experience hyperactivity and "hydrophobia".

So, the correct option is A. ( Rabies )
