1) The model of life originating on earth is called • A) Miller-Urey • B) rna world • C) Oparin-Haldane • D) extra-terrestrial • E) lateral gene transfer
2) ribozymes • A) have genotypes • B) have phenotypes • C) have both phenotypes and genotypes • D) can evolve via natural selection • E) all of the above
3-5) A) = 12 billion years; B) = 16 billion years; C) = 4.5 billion years; D) = 3.465 billion years; E) = 3.85 billion years • 3) age of the universe = 16b • 4) oldest known cells = 3.465b • 5) age of the earth = 4.5b
