Nature of Life - 1st Partial Review

Scientific theory suggested by the researcher Georges Lemaitre, where he proposes that all the matter that makes up the universe was concentrated in a single infinitely dense and hot point in space which later exploded to originate the current matter.

• Stationary state theory

• Big Bang theory

• Inflationary theory

Scientific theory proposed by Alexander Friedmann, in which it is proposed that after the big bang a braking of matter would be generated to later implode followed by a big bang again (Big-Bang Big-Crush).

• Inflationary state theory

• Oscillating universe theory

• Big Bang theory

Theory of the origin of the universe proposed by Fred Hoyle, Hermann Bondi and Thomas Gold, in which they proposed that in the process of expansion of the universe new matter would be created, which would form new galaxies to replace those that are displaced.

• Inflationary state theory

• Big Bang theory

• Stationary state theory

Scientific theory proposed by Alan Guth; establishes that in the first seconds of the explosion of the universe, matter expanded at a great speed, achieving a constant and homogeneous distribution of both matter and electromagnetic radiation.

• Big Bang theory

• Inflationary state theory

• Evolution theory

Character of science who proposed that the first living beings arose from inorganic material and that it was transformed by a process of chemical evolution into organic molecules that were dissolved in a primitive broth.

• Alexander Oparin

• Charles Darwin

• Louis Pasteur

French-born scientist who contradicted the theory of spontaneous generation and designed an experiment in which it was shown that broths of sterile organic matter, isolated from microorganisms in the environment, did not decompose.

• Charles Darwin

• Louis Pasteur

• Lamarck

They designed a system of tubes and flasks isolated from the exterior to simulate the hydrosphere as well as the atmosphere of primitive Earth. The experiment gave results, and in a matter of days the reduced components of the interior were transformed into complex organic molecules. Aminoacids, acids and urea was produced.

• Charles Darwin

• Miller and Urey

• Alexander Oparin

Scientist who managed to prove the fact that the universe is in motion, basing his conclusion on an analysis of electromagnetic waves.

• Edwin Hubble

• Gregor Mendel

• Charles Darwin

The components of the Miller - Urey model of the early atmosphere are H₂O, CH₄, H₂ and ___?

• NH₃

• CO₂

• O₂

Process that allows the genetic characteristics of organisms to change and adapt to changing environmental conditions or become extinct if the modification is not beneficial in said environment.

• Separation

• Evolution

• Change
