What did John Scott Haldane discover?
In 1905 Haldane reported his fundamental discovery that the regulation of breathing is usually determined by the effect of the tension of carbon dioxide in the blood on the respiratory centre in the brain.

What is life JBS Haldane?
Abstract. In 1929 the British biologist John Burdon Sanderson Haldane published a hypothesis on the origin of life on earth, which was one of the most emblematic of the interwar period. It was a scenario describing the progressive evolution of matter on the primitive earth and the emergence of life.
Did John Haldane invent the gas mask?
Fellow of New College, Oxford, John Scott Haldane began the slightly unorthodox technique of experimenting on himself and his family in his home laboratory in Crick Road, Oxford to develop the first prototype of the gas mask.
What is the Haldane transformation?
Haldane transformation – multiplication of inspired oxygen concentration by the ratio of expired to inspired nitrogen concentration in the calculation of oxygen consumption or respiratory quotient by the open circuit method.
Why did Haldane came to India?
In 1957, both Haldane and his wife migrated to India to accept an invitation from Prof. P. C. Mahalanobis, Director of the Indian Statistical Institute in Calcutta.
Why did JBS Haldane came to India?
Haldane was a professed socialist, Marxist, atheist and humanist whose political dissent led him to leave England in 1956 and live in India, becoming a naturalised Indian citizen in 1961.
Why did J.B.S. Haldane came to India?
What does the Haldane effect say?
The Haldane effect is a property of hemoglobin first described by John Scott Haldane, within which oxygenation of blood in the lungs displaces carbon dioxide from hemoglobin, increasing the removal of carbon dioxide. Consequently, oxygenated blood has a reduced affinity for carbon dioxide.
What causes Haldane effect?
The Haldane effect results from the simple fact that the combination of O2 with hemoglobin in the lungs causes the hemoglobin to become a stronger acid. This displaces CO2 from the blood and into the alveoli in two ways.
Why is the Haldane transformation important?
To prevent the need to measure both inspired and expired volumes, and introduce the measure of carbon dioxide, the Haldane transformation is used. This tranformation assumes that nitrogen is physiologically inert. Therefore, the volume of inspired nitrogen must equal the volume of expired nitrogen.

J.B.S. Haldane, in full John Burdon Sanderson Haldane, (born Nov. 5, 1892, Oxford, Oxfordshire, Eng. —died Dec. 1, 1964, Bhubaneswar, India), British geneticist, biometrician, physiologist, and popularizer of science who opened new paths of research in population genetics and evolution.
How many types of laws are described by JBS Haldane?
They fall into two classes — qualitative laws such as ‘All animals with feathers have beaks’, and quantitative laws such as ‘Mercury has 13*596 times the density of water’ (at 0 C and 1 atmosphere’s pressure). The first of these is a very good guide.
