BIO 105 CHAPTER 15: BACTERIA AND ARCHAEA INQUISITIVE ALL QUESTIONS WITH VERIFIED ANSWERS LATEST 2024 (COMPLETE) Although archaeans and bacteria can both live in the human belly button, there are differences between them. Which of the following is a key difference between archaeans and bacteria? - ANS-Archaeans are found in extreme environments while bacteria are not. Although bacteria and archaeans are both prokaryotes, only the archaeans are found in extreme conditions such as hot springs, where bacteria are unlikely to survive. - ANS-prokaryotes, archaeans, hot springs, bacteria Although most of the organisms researchers have found in the belly button are bacteria, they were able to identify two archaean species on one "particularly fragrant" individual as well. Which of the following statements accurately describe archaeans? - ANS-CORRECT ANSWERS - Archaeans are prokaryotic. - Archaeans are found in extreme environments. INCORRECT ANSWERS - Archaeans have mitochondria. - Archaeans are more closely related to bacteria than eukaryotes. As part of a research team assigned to identify possible archaeans present in a soil sample, you decide to recreate some of the conditions in which archaeans are found in hopes of encouraging their growth in the lab. What could you add to your cultures to encourage archaean growth? - ANS-CORRECT ANSWERS - vinegar - very hot water - table salt INCORRECT ANSWERS - sugar - fertilizer Bacteria use hairlike projections called pili to swim through liquid environments. - ANS-FALSE Biological oceanographers are investigating the ability of ocean microbes to combat climate change through the absorption of atmospheric carbon dioxide that has dissolved into surface ocean waters. Order the different metabolic strategies from the most promising to the least promising for prokaryotic carbon sequestration. - ANS-photoautotroph, chemoautotroph, photoheterotroph, chemoheterotroph Bioremediation is the use of living organisms to clean up environmental disasters, such as an oil spill.
