- What evidence is there for the hypothesis that life originated on Earth by the creation and polymerization of small organic molecules by natural processes?arrow_forwardIs it possible that life will exist in a closed container? How and why?arrow_forwardIn the 1950s, scientists Miller and Urey conducted a classic experiment in which water, methane, ammonia, and hydrogen were sealed in a flask containing a pair of electrodes. An electric spark was fired between the electrodes, and after a week's time, they found that amino acids were present in the flask. 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.arrow_forward

- Which of the following questions about the origin of life on Earth is most scientifically testable? * Why were the earliest life-forms created using only twenty amino acids? Did life originate to make the universe a better place? Was catalytic RNA used by ancient organisms as a stepping stone to acquire protein enzymes? Can simple organic molecules form spontaneously in an oxygen-free atmosphere?arrow_forwardYou have learned the process of the Scientific Method since elementary school science lessons.

- An astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins. Which of the following conclusions about this form of life would be most justified? These organisms can produce proteins no more than 30 amino acids in length. These organisms must produce 30 different forms of mRNA Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet. Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet. These organisms cannot produce more than 30 kinds of protein.arrow_forwardThe origin of life happened under planetary conditions very similar than those at the present somehow similar to those at the present still uncertain for science different than those at the presentarrow_forwardIn the Urey-Miller experiments with the origin of life forms, what was the purpose of the electric sparks passed through a mixture of gases? Group of answer choices simulate lightning simulate sunlight simulate temperature produce rain from clouds sterilize the gasesarrow_forward
