AND ANSWERS 100% PASS
Which condition(s) are most likely to be found on a habitat near or on the hydrothermal vents
of Lost City? - ANS extreme heat, extreme pressure, basic pH, and ?????? (all of the above)
The habitats surrounding a deep-sea hydrothermal vent support differing microbial ????
because of variation in - ANS temperature, pH, hydrogen concentration, and methane
concentration (all of the above)
Most of the organisms found at Lost City are - ANS prokaryotes
Which organisms would most likely NOT be found at or near a deep-sea hydrothermal vent? -
ANS aerobic bacteria
The hydrothermal vents of Lost City are unique because - ANS they have different chemistry
and inhabitants
Some microbes found at Lost City - ANS use hydrogen or an energy source
Where would a scientist most likely find an archaean when sampling carbonate hydrothermal
vents? - ANS inside the chimney beside the warm vent flow
All of the following are true of hydrothermal vents, EXCEPT - ANS the temperatures never get
higher than 60 degrees celsius

, How are samples collected from Lost City? - ANS by using remotely controlled machines
Why would a researcher be slow, careful, and meticulous while vacuuming a specific ?????
deep-sea chimney? - ANS to avoid cross contamination of biological species, to avoid
breaking the chimney, to document a specific environment or habitat, and because it is done
remotely and ???? skill (all of the above)
Why would a researcher process microbes collected from a deep-sea chimney in an ????? ???? -
ANS to prevent oxygen from harming the microbes and to control the environment
At which temperature would you incubate microbes collected at Lost City? - ANS would vary,
depending on collection point
Lost City microbial samples must be processed in an anaerobic glove bag because - ANS The
microbes are anaerobic and might be damaged if exposed to oxygen
Which of the following does NOT refer to a prokaryotic organism? - ANS has organelles
Which is NOT true of prokaryotes - ANS They are exclusive to land
A prokaryote has all of the following structures EXCEPT - ANS mitochondria
Which statement about prokaryotes is FALSE - ANS All prokaryotes are bacteria
All of the following are true of prokaryotes EXCEPT - ANS They are less numerous than
eukaryotes
All of the following are TRUE of eukaryotes EXCEPT - ANS their DNA is found in cytoplasm
