Nitrogen fixation is a natural process by which inert or unreactive forms of nitrogen are transformed into usable nitrogen. Why is this process important to life? Given what you have learned about the hydrogen bonding shared between nucleic acids in DNA, which pair is more stable under increasing heat: adenine and thymine, or cytosine and guanine? Explain why. Which of the following is not an organic molecule: methane (CH4), fructose (C6H12O6), rosane (C20H36), or ammonia (NH3)? How do you know?
Critics of evolution often cite the fact that several hypotheses are being tested to help explain various stages of the origin of life. Explain how having several hypotheses for the evolution of monomers does not negate the fact that evolution of monomers was the first stage in the evolution of life?
Some scientists propose that Silicon might be a suitable alternative to Carbon as the basicatom that forms the “backbone of life”. Why is this?
The following is a synthesis sequence or progression that is a hypothesis for Chemical evolution: elements, ionic and covalent bonding to form simple molecules, these simple molecules form simple organic monomers, the monomers undergo dehydration synthesis to form bio polymers, formation of micelles (Pre cells). This concept a) can only be observed in living cells, b) is a theory that proves that life could not evolve on other planets. c) is a hypothetical model that can be confirmed in the laboratory, d) is a hypothesis that has no supporting evidence from rocks that predate the presence of cells in the fossil record. e) These are all true.
why is carbon considered the backbone of life?
In the prebiotic world, the chemical evolution scenario proposes that: Small inorganic compounds gave rise to simple biomolecules from meteorites impacts on the Earth surface. Large inorganic compounds gave rise to simple biomolecules when sparked by lighting Small inorganic compounds gave rise to simple biomolecules when dissolved in sulfuric acid Simple biomolecules were created by primitive bacteria Small inorganic compounds gave rise to simple biomolecules when sparked by lighting.
If functional proteins are so unlikely, how could life have evolved?
Organic molecules were originally named so, because they were thought to only be produced by living creatures. Are there ways organic molecules be made by outside of living creatures? If so, what are they?
What evidence is there for the hypothesis that life originated on Earth by the creation and polymerization of small organic molecules by natural processes?
Are the atoms and basic molecules that compose living things different from the molecules that make up nonliving things? Where were the atoms in living things formed?
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.
