Do bacteria and archaea have more or less diversity than eukaryotic organisms? Choose the best reason why or why not. Group of answer choices Bacteria and archaea are LESS diverse. One reason is that they cannot become resistant to antibiotics. Bacteria and archaea are MORE diverse. One reason is that they transfer genes asexually through horizontal gene transfer. Bacteria and archaea are MORE diverse. One reason is that they can become resistant to antibiotics. Bacteria and archaea are LESS diverse. One reason is that they transfer genes asexually through horizontal gene transfer.
Prokaryotic organisms have recently been divided into two domains, Bacteria and Archaea. Which of the following is NOT correctly matched in terms of Domain and prokaryote? Eubacteria, spirochetes Archaea, halophiles Eubacteria, cyanobacteria Archaea, methanogens Archaea, spirochetes
Archaea (formerly known as archaebacteria) is one of the three major divisions of living organisms; the other two are eubacteria and eukaryotes. Nanoarchaeum equitans is in the Archaea domain and has one of the smallest genomes known, about 0.5 Mb. How can an organism complete its life cycle with so little genetic material?
Why do some microbiologists disagree with classifying bacteria and archaea as “prokaryotes”?
Which of the following statements is correct for archaea?(a) Archaea resemble eukaryotes in all respects.(b) Archaea have some novel features that are absent inother prokaryotes and eukaryotes.(c) Archaea completely differ from both prokaryotes andeukaryotes.(d) Archaea completely differ from prokaryotes Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.
Why were Archaea originally thought to be simply unusual forms of Bacteria? What lines of evidence showed this domain to form a distinct branch on the tree of life?
Why do microbiologists believe that the Archaea were the type of microbes from which all other life descended?
List several characteristics that bacteria and archaea have in common and that distinguish them from eukaryotes.
Consider the fact that the use of 16S rRNA sequencing as a taxonomic and phylogenetic tool has resulted in tripling the number of bacterial phyla. Why has the advent of this genetic technique expanded the currently accepted number of microbial phyla?
The unicellular, rod-shaped bacterium E. coli is~2 μm long and 0.8 μm wide, and has a genomeconsisting of a single 4.6 Mb circular DNA molecule. The unicellular archaean Methanosarcinaacetivorans is spherical (coccus-shaped) with adiameter of 3 μm and has a 5.7 Mb circular genome.The unicellular eukaryote Saccharomyces cerevisiaeis roughly spherical, with a diameter of 5–10 μm.It has a haploid genome of 12 Mb divided among16 linear chromosomes. Given these descriptions,how could you determine whether a new, uncharacterized microorganism was a bacterium, an archaean,or a eukaryote?
Which of the following statements is correct? Please select all that apply. Select one or more: a. Parasitism between bacteria and archaea caused complex interactions that eventually gave rise to eukarya. b. While bacteria are prokaryotes, archaea are neither prokaryotic, nor eukaryotic but classified as a 3rd cell type. c. Prokaryotes are classified further based on whether they are unicellular or multicellular organisms. d. The molecular biologies of archaea and eukarya show a greater proportion of similarities than those of eukarya and bacteria. e. Prokaryotes could not make photosynthesis until chloroplast endosymbiosis evolution. f. The last universal common ancestor most likely had a primitive prokaryotic cell organization. g. Endosymbiosis of chloroplast precedes that of mitochondria.
In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common? Question options: They both have identical cell walls. They both have prokaryotic cells. They both thrive in extreme environments. They both are able to live only under anaerobic conditions.
