3.1 Carbon atoms found on earth were synthesized: 1) by the breakdown of water in lakes 2) during the first millisecond of the big bang 3) by photosynthesis 4) in the interior of stars and we are all formed from stardust 5) by respiration 3.2 Proteins are better catalysts than RNA because 1) RNA contains more phosphate than proteins 2) RNA is acidic 3) Proteins contain nitrogen 4) there is more diversity in the nucleotides than in the amino acids 5) there is more diversity in the amino acids than in the nucleotides 3.3 Enzymes are: 1) proteins 2) DNA 3) molecules that speed up reactions 4) both 1 and 2 5) both 1 and 3 3.4 Occam’s Razor is used to: 1) make anatomical section of liver tissue 2) maximize the number of data points 3) minimize the number of data points 4) maximize the number of assumption 5) minimize the number of assumptions 3.5 Clays are considered to be evolutionarily challenged because: 1) they can not replicate as fast as nucleic acids 2) they are good catalysts 3) they contain cations and anions
