Inventors and Scientific Discoveries

Wendell Meredith Stanley was the first to crystallize the tobacco mosaic virus (TMV) in 1935, demonstrating that viruses could be isolated in crystalline form, which was crucial in understanding their nature. Von Manuel, Jack Karl, and Ronald Ross (who worked on malaria) are not associated with this discovery.

Yes, it is correct. Planaria is the first animal which shows ‘eye’ like structure that are spots and light sensitive.

1995 - 100 = 1895. X-rays were discovered by Wilhelm Röntgen in 1895, so their 100th anniversary would indeed be in 1995. The other options (detergents, photography, diesel engine) were discovered or invented in different years.

William Bayliss and Ernest Starling discovered secretin hormone in 1902. It was the first chemical messanger that was identified.

“Origin of Species” is a world of scientific literature. The book ‘Origin of Species’ was written by Charles Darwin. 

The Greeks discovered naturally occurring magnets of magnetite in Turkey.

The term CAM may have been coined by Ranson and Thomas in 1940.

This is the correct option. Robert Hooke concluded that cork is made of tiny cells.

This is the correct option. Schleiden was the scientist who in 1838 suggested that all plants are made up of cells.

Nikola Tesla invented the AC induction motor in 1887-1888, receiving US Patent 381,968 in 1888. This invention revolutionized electrical power transmission and distribution, making AC systems practical and superior to DC for long-distance power delivery.

Charles Babbage is widely regarded as the 'Grandfather of Computer' or 'Father of the Computer' for designing the first mechanical computer, the Difference Engine (1822) and the more advanced Analytical Engine (1837). His pioneering work laid the foundation for modern computing concepts like programmability, storage, and input/output mechanisms. The other options (Bernal Wahn, Carroers, Franklene) are not recognized figures in computing history.

John Logie Baird (J.L. Baird) is credited with inventing the first mechanical television in the 1920s. His system was the first to demonstrate working television transmission.

The scientist who pointed out for the first time that inborn errors of metabolism are controlled by hereditary factors, and are inherited in a Mendelian fashion was Garrod.

Richard Jordan Gatling invented the Gatling gun in 1861-62. It was an early rapid-fire gun with multiple barrels rotated by a hand crank, precursor to modern machine guns.
