Students have asked these similar questions
Compare and contrast the evolutionary theory and creationism theory on the origin of life molecules, the origin of prokaryotes, and the origin of eukaryotes.
what simple organic molecules were likely the precursors of life?
a. water and proteins
b. amino acids and nucleotides
c. oxygen and carbon
d. prokaryotes and eukaryotes
Here is the question: What was the likely source of the raw material incorporated into the first life forms? I believe it is carbon, but I don't know why it is carbon. What I mean is, why is carbon considered the thing that makes something alive? Why are eukaryotes and prokaryotes simply considered alive just because they have carbon. Would that mean that carbon is alive because carbon has carbon? I would appreciate an anwser because I'm really trying to understand everything I run across. I love educating myself and I'm on a quest for knowledge. Thanks guys!

- Which result from the Miller and Urey experiment provides evidence that the molecules of life could have spontaneously been produced in the ancient Earth environment? a After their experiment, they produced DNA from amino acids. b They showed how DNA can be produced from simple molecules that included water, oxygen, carbohydrates, and lipids. c Their experiment produced amino acids—the building blocks of life—from chemicals that existed in the environment of ancient Earth. d Miller and Urey's experiment provided evidence that showed that although oxygen was lacking in the environment of ancient Earth, it could be readily made from the decomposition of rocks and minerals.arrow_forwardIf living cells were produced in a test tube from nonbiological components by chemical processes, would this accomplishment prove that life evolved in asimilar manner billions of years ago? Explain your answer.arrow_forwardThe endosymbiotic theory argues that prokaryotes become some of the organelles of early eukaryotic cells. All of the following support this hypothesis Except: A. The mitochondria and chloroplasts have their own DNA and are nearly idential to some free-living prokaryotes b. Mitochondria and chloroplasts are nearly idential to some free-living prokaryotes. c. Mitochondria and chloroplasts have their own DNA d. The vacuoles can come and go across the plasma membranearrow_forward
- What event is thought to have contributed to the evolution of eukaryotes? a. global warming b. glaciation c. volcanic activity d. oxygenation of the atmospherearrow_forwardIn what order did events occur that led to life on Earth? (1) appearance of aerobic organisms, (2) appearance of photosynthetic organisms, (3) appearance and increase of O2 in the atmosphere, (4) self-replicating RNA developsa. 4, 2, 3, 1b. 2, 3, 1, 4c. 3, 1, 4, 2d. 1, 2, 4, 3arrow_forwardScientists Stanley Miller and Harold Urey set up an experiment modeling the environmental conditions thought to exist during the early stages of Earth's formation. The setup of Miller and Urey's experiment is shown below. Which conclusion about the origin of life could be drawn from the potential results of this experiment? Life assembled from chemical building blocks. Life began when water vapor became electrified. Life evolved from the DNA of simple unicellular organisms. Life began when salt water caused a mutation in an ancient virus.arrow_forward
