Step by step
Solved in 2 steps
- How did the Miller-Urey experiment impact the way scientist think about the origins of lifeWhy does there appear to have been only one origin of life on earth? Why are there not multiple origins? Why is life not originating still?What experimentation has been done on finding the source or raw material for the first life on earth? WhT has been discovered and by who?
- Which molecule -DNA or RNA- do scientist believe was found in the first life form on Earth? Why do scientist believe this molecule was first to form life?What is the most logical theory on the topic of the Origin of Life?Based on the Origin of Life by John H. McClendon, how did life on earth start based on the different theories?
- Why is the reducing nature of early Earths atmosphere key to the OparinHaldane theory of the origin of molecules necessary for life?What does Oparin-Haldane Hypothesis assume about Earth’s primordial atmosphere? Why would this have been important for the origin of biologically significant molecules?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.
