Give the stratigraphic arrangement of rock layers as shown below, the circles represent places where fossils were found. Match the fossil with the fossil collection site (put the collection site number in the blank on the answer sheet). Assume the level 4 is where you find the extant species A, B, C, D, E, and humans. 1 3 Site 2-rich in ancient fish fossils Site 3 - rich in lungfish and coelacanth-like fossils Site 6- contains T-rex and various other dinosaurs Site 8-saber tooth tigers and ground slot fossils 6 7. A-H ancestor (choose between sites 2 and 3) 8. E-H ancestor (choose between sites 2 and 3) 9. Putting aside species A-E, let us say that the following layers in this stratigraphic diagram have the following fossil deposits: Which site would you expect to find a therapsid fossil? A) site 4 B) site 5 C) site 7 7

ATP Roles of nucleotides FAD flavin adenine dinucleotide coenzyme nicotinamide adenine dinucleotide s-adenosyl mothinnine .. 13. Above image shows some of the diverse roles that nucleotide-derived compounds play in the cel. This has been used to argue for an RNA-world hypothesis for the origin of life. Is this a credible claim, and if so or not, why or what not? A) Yes. Because the nucleotides code for genetic information in the cell, so one would expect that these molecules would find their way into being incorporated widely throughout biochemistry of life B) Yes. The very early biochemistry of life likely involved nucleotides, acting as information and energy currency, and these compounds were incorporated into other diverse compounds over millions of years. c) Yes. Nucleotides have the greatest molecular fitness, so they occur widely. D) No. There are merely too many nucleotides in the cell, and many of them weasel their way into biochemical reactions they have no business partaking in. E) No. None of these compounds are naturally occurring.
