Question

Bergey was instrumental in developing that helped (and continues to help today) researchers compare their unknown cultures with know B) lyophilizers D) a manual A) type strains G) standardized tests/equipment E) choices C & D, but not A & B 10 For most photosynthetic or chemolithotrophic cells, they will need toin order that they can generate which is required for bionynthetie (anabolic) reactions. A) have a source of glucose.... ATP B) move electrons via ATPase a terminal electron acceptor C) reduce an electron carrying coenzyme .....reduced carbon from CO D) have a source of light.... ATTP E) avoid problems related to free radicals .. a specific intermediate Chemolithotrophic bacteria will often utilize something like as their energy sources while mostly using as their terminal electron acceptor B) NO HaS D) H... pynuvic acid A) SO4...O C) organie matter O E) H2 O2 12- Modular/Horizontal evolution refers to the__ which tends to have effects in other similar cells of the A) long-term accumulation of mutations habitat where they live B) transfer of specific mutations culture C) transfer of whole pieces of DNA..... culture collection where they came from D) transfer of discrete pieces of DNA..... same generation of that species E) B and C, but not A and D 13. Oparin and Haldane were noted for coming up with the idea that A) one bacteriophage would lead to one plaque B) frame shift mutations were caused by intercalating agents C) bacteria that use glycolysis can also use aerobic respiration D) over antibiotic use could lead to antibiotic resistant strains of bacteria E) none of the above 14Carl Woese was best known for A) providing evidence that supported the work done by Miller and Urey B) isolating archaebacteria from unusual environments like thermal springs C) developing the technique used to identify bacteria from unusual environments D) suggesting that chloroplasts in modem plants once were ancient eukaryotes E) none of the above 15. When Troland proposed his autotrophic origins hypothesis to address origin of lfe questions skeptics were generally upset due to A) his lack of a mechanism to include a nucleus in his cells B) his lack of a mechanism to generate a lipid cell membrane C) his lack of a mechanism to include a mitochondrion in his cells D) his lack of a discussion to include spores in his cells E) none of the above

Explanation / Answer

9) E. A manual Bergey was instrumental in developing standardized tests/euipment that helped researchers in compairing unknown cultures with known species.

10) A. Have a source of glucose.......ATP

11) E. Chemolithotropic bacteria uses H2as energy source while mostly using O2 as terminal electron acceptor

12) Horizontal evolution refers to the transfer of discrete pieces of DNA which tends to have effect in other similar cells of the same generation of that species.

13) E. None of the above. Two postulates of Oparin and Haldane to origin of life are: a) Life originated from pre-existing, non-living organic molecules. b) Formation of life was preceded by chemical evolution.

14) E. None of above. Woese is famous for defining the Archaea by phylogenetic taxonomy of 16S ribosomal RNA.
