- The Miller- Urey Experiment In the Stanley Miller and Harald Urey designed experiments that tested Alexander Oparin's and J.B.S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler organic precursors. Miller and Urey used an apparatus that recreated the conditions of what a primitive Earth was thought to consist of at the time. Methane, hydrogen , and steam were all Included to recreate conditions similar to that of a primitive Earth. Their goal was to create complex organic molecules from the simple organic molecules that were believed to be part of primitive Earth's makeup. The Miller- Urey experiment was run for a week and the samples collected were analyzedAnalysis showed that some of the carbon in the apparatus was converted to amino acids molecules, In later experiments , similar to Miller and Urey's, it has been shown that it is possible to form all 20 amino acids commonly found in…A) Briefly explain what oxygen is? B) Is the surplus of oxygen in our atmosphere a requirement for life, or a product of life? provide 3 points of evidence with explanation of each pointStatement A: The flow of matter across the earth’s subsystems involves the transformation of matter into energy. Statement B: The breakdown of glucose molecule into H2O and H2O in the process of cellular respiration corresponds to the formation of a chemical form of energy adenosine triphosphate Both statements A and B are correct Statement A is correct, statement B is incorrect. Statement A is incorrect, statement B is correct Neither statement A nor statement B is correct.
- Where Do the O Atoms in Organisms Come From? Name three principal inorganic sources of oxygen atoms that are commonly available in the inanimate environment and readily accessible to the biosphere.A new type of beans produced by the research sector of a food manufacturer were recently introduced into the market of Namibia. Immediately after hitting the market, the consumers of the food product were affected with allergic reactions and certain metabolic disorders. What scientific term is used to categorize these foods? Explain the term. And, why is the production of these foods desirable, write with examples and explanation.Why is carbon essential to all known life in earth ?
- The law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.Using examples explain how biology can be studied from a microscopic approach to a global approach? Give an example of how applied science has had a direct effect on your daily life? Describe there way in which carbon is critical to life? Describe the interrelationship between protons,neutrons and electron's and the ways in which electron's can be donated or shared between atoms?Radioactive isotopes are routinely used to investigate processes in living things. In 1941, biologists exposed photosynthesizing cells to water containing a heavy oxygen isotope, designated 18-O. The labelled isotope appears in the oxygen gas released in photosynthesis, demonstrating that the oxygen came from water. Explain where the 18-O would have ended up if the researchers had used 18-O-labelled carbon dioxide.
- “Photosynthesis is the single most important process for life on Earth.” Discuss this statement in some detail.why is all the carbon on earth not used if every living thing requires it(a) It can be argued that, if life were to exist elsewhere in the universe, it would require some process like photosynthesis. Why is this argument reasonable? (b) If the starship Enterprise were to land on a distant planet and find no measurable oxygen in the atmosphere, could the crew conclude that photosynthesis is not taking place?
