The types of metabolism that may have initially evolved on early earth include all the following, except Question 13 Your answer is CORRECT. One reason why RNA molecules are the leading candidate as the first informational molecule is that Question 14 Your answer is CORRECT. Reductive evolution is Question 15 Your answer is CORRECT. Which is applicable to genes used as molecular clocks? Question 16 Your answer is CORRECT. Which is not accurate regarding the three domains of life? Question 17 Your answer is INCORRECT. All are true regarding endosymbioses, except Question 18 Your answer is CORRECT. Bacteria of the genus __________ are all Gram-positive, rod-shaped, aerobic, endospore formers; pathogenic members of this group cause anthrax and others are insect pathogens. Question 19 Your answer is INCORRECT. What do all the Proteobacteria have in common? Question 20 Your answer is INCORRECT. Which of the following is mismatched? Question 21 Your answer is INCORRECT. Certain bacteria have symbiotic relationships with other organisms. Which bacterial type is correctly paired with its proper description? 1. obligate anaerobe important to digestion in humans 2. nitrogen-fixingsymbionts of certain leguminous plants 3. obligate intracellular parasite that can cause disease in humans 4. pathogen that inserts segments of its DNA into the plant host chromosome Question 22 Your answer is CORRECT. The possession of internal flagella that occupies the periplasmic space of the cell, is wrapped around the plasma membrane of the cell, and includes Treponema and Borrelia are in the phylum Question 23 Your answer is INCORRECT. Which is not correctly matched? Question 24 Your answer is CORRECT. All of the following major groups contain phototrophic bacteria, except Question 25 Your answer is INCORRECT. Which of the following is unique to archaea? Question 26 Your answer is CORRECT. Another scientist has given you a culture of an archaea that is an extreme thermophile and is an obligate anaerobe. It does not produce methane and will not grow under high salt conditions or in very acidic conditions. What group does this organism belong to? Question 27 Your answer is INCORRECT. Which pair is mismatched? Question 28 Your answer is INCORRECT. Regarding methanogens, which is a false statement? Question 29 Your answer is INCORRECT. Which of the following is not applicable to the Haloarchaea? Question 30 Your answer is CORRECT. Archaea that live by black smokers at hydrothermal vents under the ocean are generally also Question 31 Your answer is CORRECT. Nanoarchaeota are distinguished from other archaeal divisions in that Question 32 Your answer is CORRECT. __________ processing refers to steps in product recovery and purification. Question 33 Your answer is CORRECT. Free points Question 35 Your answer is CORRECT. BONUS For a given electron donor, the most energy will be released when oxygen serves as the final electron acceptor because BONUS Since many prokaryotic genes have been acquired via horizontal gene transfer, this can complicate the interpretation of molecular phlyogenies. To minimize this effect, gene sequences used for such comparisons employ operational genes, such as those involved in metabolism or pathogenicity, since these are unlikely to have been acquired by horizontal gene transfer.
