Which one of the following people first peeped into a mosquito's stomach and proved that mosquito spreads malaria. Later on, he was awarded the Noble Prize for Medicine for this discovery.  Correct Answer <span style="">Ronald Ross</span>

​Concept:

  • Various diseases are caused by animals or are transmitted by them to humans.

Explanation:

About Dr Ronald Ross:

  • Sir Ronald Ross (13 May 1857–16 September 1932) was a British medical doctor.
  • He received the Nobel Prize for Physiology or Medicine in 1902.
  • His work on the transmission of malaria made him become the first British Nobel laureate born outside Europe.
  • He discovered the malarial parasite in the gastrointestinal tract of a mosquito in 1897.
  • He proved that malaria was transmitted by mosquitoes.
  • He further laid the foundation for the method of combating the disease.

About Malaria:

  • Malaria spreads only by the disease-carrying mosquitoes.
  • The vector of malaria is the female anopheles mosquito.
  • Malaria spreads only when a female mosquito that has bitten a malaria patient bites another person.
  • A blood test is done to check if a person has malaria or not.
  • People with malaria get a fever with chills, sweating, headache, nausea and rigours.
  • Malaria is caused by protozoan Plasmodium.
  • In early times, the dried and powdered bark of the Cinchona tree was used to make medicine for malaria.
  • Earlier people used to boil the bark powder and strain the water which was given to patients.
  • Now tablets are made from this in the form of quinine, chloroquine is given to patients.

​Thus, Dr Ronald Ross discovered the parasite of Malaria and got a Nobel prize for this.

Additional Information

Dr Beaumont:

  • William Beaumont (November 21, 1785 – April 25, 1853) was a surgeon in the U.S. Army.
  • He became known as the "Father of Gastric Physiology" following his research on human digestion.
  • In 1822, an employee of the American Fur Company named Alexis St. Martin was accidentally shot.
  • Dr Beaumont treated his wound but expected St. Martin to die from his injuries.
  • Despite this dire prediction, St. Martin survived but with a hole in his stomach that never fully healed.
  • He was hired as a handyman by Dr Beaumont to observe digestive processes.

About Gregor Mendel:

  • Gregor Mendel, a 19th-century Augustinian monk.
  • He was born in a poor farmer’s family in Austria in 1822.
  • He is called the father of modern genetics.
  • He found that the pea plant has some traits which come in pairs (called an allele).
  • Mendel's pea plant experiments conducted between 1856 and 1863 established many of the fundamental laws of heredity.
  • It is now referred to as the laws of Mendelian inheritance.

Read the passage carefully and select the best answer to each question out of the given four alternatives.
Public opinion may be passive and false or active and real. It is claimed in theory that all governments are ultimately based on the opinion or sanction of the governed. But we find that in practice the people's rights are often trodden down and tyranny and oppression are allowed to continue. The government does it not because the people want it to do so but because they are too idle, too uneducated and too disunited or timid to oppose the govern ment. Such public opinion is passive and false and not an active verdict. But when we find people alert, intelligent and determined to let the government know their will, when they want to exercise actively their voice in the management of their country, we have an instance of true or active public opinion. True public opinion is formed by and expressed through the press, the platform, political parties and educational institutions. These have sacred duties to perform, duties on which depends the ultimate good of the entire community. The press today wields a tremendous influence, So it should support the causes and move ments and condemn the wrong one's and thus teach people to form correct opinion. A free and fair press ventilates the grievances of the public. Thus a healthy relationship develops between the people and the government through out an unbiased press. Political parties also help to create and regulate opinions. No less important part is played by the educational Institutions which train the minds of the young people who will be the citizens of tomorrow. It has been said that modern Germany and China have been made by their universities. It is necessary that the young and the growing minds should imbibe the spirit of fellow-feeling, the spirit of tolerance, the habit of compromise, and show due regard for the feelings and opinion of others without which a democratic society cannot function, let alone succeed. When there is true awakening of the people, we shall have the real and conscious public opinion. And justice will reign on earth and truly will the voice of the people be the voice of God.
According to the passage, which of the following is needed from the people to have true or active public opinion? 1. Alertness
2. Determination
3. Intelligence
4. Raising their voice
