- 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.arrow_forwardOrganisms require ----- and ------ to maintain themselves, grow and reproduce. a.

- If all living organisms have the same pattern, then humans would have the same genetic code as a worm because all species have the same repeated pattern, DNA could not provide the variety needed for the genetic code. Was the hypothesis supported? Be sure to explain your reasoning! (Sentence starters: “Yes, my hypothesis was supported. I know this because…” or “No, my hypothesis was not correct. It was proven to be false because…”)arrow_forwardGenetic information flows in one direction. Which of the following exceptions can actually occur? a. DNA to Protein b. RNA to DNA c. Protein to DNA d. Protein to RNAarrow_forwardHuman DNA contains almost twice as much information as is needed to code for all the substances produced in the body. Likewise, the digital data sent from Voyager II contained one redundant bit out of every two bits of information. The Hubble space telescope transmits three redundant bits for every bit of information. How is entropy related to the transmission of information? What do you think is accomplished by having so many redundant bits of information in both DNA and the space probes?arrow_forward
