In the 1950s, Miller and Urey obtained support for the hypothesis that simple organic molecules needed to build more complex biomolecules could be synthesized from inorganic compounds under conditions thought to simulate those on early Earth. Since then, additional information has emerged that weakens this support. Which statement below describes the reason why results from the Miller-Urey experiments are no longer considered strong evidence of a prebiotic-soup origin of life? A. The Miller-Urey experiments did not include clay, which is known to have been present during Earth's early history. B. The type of energy used in the Miller-Urey experiment was unrealistic based on what is known about early Earth conditions. C. The temperature conditions used in the Miller-Urey experiment could not have been present during Earth's early history. D. Some of the gases used in the Miller-Urey experiment are now known not to have been present on early Earth.

“Life has profoundly changed the Earth.” Explain whether or notthese experimental results support this statement.
Which of the following was the least likely objective of the Urey-Miller experiment? Group of answer choices To demonstrate that oxygen can be produced by plants. To recreate the conditions of the Earth before life existed and produce the molecules necessary for life from primordial inorganic matter (water, methane, ammonia, and carbon dioxide). To build a case (though not necessarily prove) that life can originate from nonliving matter through natural means. To demonstrate that organic molecules like amino acids (building blocks of protein) and nucleotide bases (building blocks of DNA) do not necessarily originate only from living matter. To demonstrate that lightning may have been the essential energy source (early in Earth's evolution) in the production of molecules essential for life.
Which of the following is least reasonable regarding the Urey-Miller experiment? Group of answer choices The experiment was an important breakthrough in the study of the origin of life. The experiment conifirmed that several of the key molecules of life could have been synthesised naturally on the primitive Earth. The amino acids and other molecules produced in the experiment, and possibly present in the early atmosphere, could have participated in 'prebiotic' chemical processes, ultimately creating life. This experiment, and others which followed, suggests that simple biologically significant molecules can evolve naturally under sets of conditions that may have existed not only on early Earth, but potentially elsewhere in the solar system and beyond. The experiment was the first demonstration of abiogenesis (life from non-life).
In the 1950s, scientists Miller and Urey conducted a classic experiment in which water, methane, ammonia, and hydrogenwere sealed in a flask containing a pair of electrodes. An electric spark was fired between the electrodes, and after a week'stime, they found that amino acids were present in the flask. Which of the following best explains the significance of thisexperiment in explaining the origin of life on Earth?

Which of the following best explains the significance of this experiment in explaining the origin of life on Earth? A. It showed that any raw materials could produce the compounds necessary for life to exist on early Earth. B. It showed that life must have started somewhere else since organic compounds only come from living thin C. It showed how biological molecules can be formed from the very simple molecules that were available on early Earth. D. It showed how lightning can cause organic matter to decompose into amino acids, which were the first molecules on early Earth.
What evidence is there for the hypothesis that life originated on Earth by the creation and polymerization of small organic molecules by natural processes?
What does Oparin-Haldane Hypothesis assume about Earth’s primordial atmosphere? Why would this have been important for the origin of biologically significant molecules?
Assume a flat Friedmann-Robertson-Walker universe, dominated by a fluid with equation of state P = c²wp, where the equation of state parameter w is a constant. a) Calculate p(a), the dependence of the energy density p on the scale factor a. b) Determine the value of the equation of state parameter w that gives rise to a scale factor evolution a(t) x t.
9) Miller and Urey were able to support the hypothesis that life could have arisen through chemical/physical processes available on Earth 3.5+ billion years ago by heating and cooling CH4, NH3, H2, and H2O.

A) Lipids formed in these conditions B) Amino acids formed in these conditions C) Nucleic acids formed in these conditions D) Carbohydrates formed in these conditions
