Question

Who introduced the system of scientific nomenclature of organisms?
A. Robert Whittaker
B. Carolus Linnaeus
C. Robert Hooke
D. Ernst Haeckel

Answer 1

He is a Belgian priest and he suggested the big bang theory in the year 1920.

Complete answer: Charles Darwin was an English naturalist.
He was the one who proposed the scientific theory of evolution by natural selection.
1. Stanley Miller was an American chemist. He made landmark experiments in the origin of life. He demonstrated that organic compounds can be synthesized from inorganic compounds by using fairly simple chemical processes.
2. Stanley B. Prusiner is an American neurologist. He is the director of the Institute of Neurodegenerative Diseases. He discovered prions, a class of infectious self-reproducing pathogens composed of protein.
3. Georges Lemaitre was a Belgian Catholic priest.
He was also a mathematician, astronomer, and professor of physics. He proposed the big-bang theory in 1920

Additional information: Georges Lemaitre was the first to identify that the recession of nearby galaxies can be explained by a theory of expanding universe.
He proposed ‘the hypothesis of primeval atom’ on the origin of the universe and it was later names as Big Bang theory. The big bang theory explains how the universe began.
It is the idea that the universe first started as a single point, it further expanded and stretched to grow as large as it is now. It is a cosmological model of the observable universe. This theory is compatible with Hubble-Lemaitre law.

Hence, the correct option is ‘B’.

Note: Stanley Prusiner along with Hubble formulated a law. He later came to the conclusion putting forth the hypothesis of the primeval atom which was later named to be the Big-Bang theory.
