- What do you mean by domain bacteria? Explain it briefly.arrow_forwardWhich of the following contribute(s) to the differences between the Archaea and the bacteria? O A. Archaea lack muramic acid. O B. Archaea have isopranyl glycerol ethers rather than fatty acid esters in their membrane lipids. O C. Archaea differ from bacteria in their tRNA composition, ribosome structure, antibiotic sensitivity, translation elongation factors, initiator TRNA, and DNA-dependent RNA polymerase structure. O D. all of thesearrow_forwardMany of the first prokaryotes to be cultured in a scientific lab were human or animal pathogens. Why would these species be more readily cultured than non-pathogenic prokaryotes? a. Pathogenic prokaryotes are hardier than nonpathogenic prokaryotes. b. Non-pathogenic prokaryotes require more supplements in their growth media. c. Most of the necessary culture conditions could be inferred for pathogenic prokaryotes. d. Pathogenic bacteria can grow as free bacteria, but non-pathogenic bacteria only grow as parts of large colonies.arrow_forward
- A recent study found that 480 Streptomyces strains freshly isolated from the soil are resistant to at least six different antibiotics. In fact, some isolates are resistant to 20 different antibiotic drugs.Why do you think these bacteria (which are neither pathogenic nor exposed to human use of antibiotics) are resistant to so many drugs? What might be the implications for human bacterial pathogens?arrow_forwardWhich domain, Archaea or Eukarya, is more closelyrelated to Bacteria? What evidence is there to justifyyour answer?arrow_forwardWhat is an original research? Do you think the following are ideas that may be considered as original? Support your answer with logical reasons in each case : a. Investigation of size of bacterial cells b. Evaluation of impact of CO2 on the environment c. Diversity of microorganisms in the fields of Kohat University d. Investigation of new compounds in a bacterial culture e.

- Draw a prokaryotic cell and show the different target parts of the cell where antibiotics can attack. Give an example of the antibiotic that attack these parts. schematic drawing will do, I can just draw it on my ownarrow_forward1.) Your roommate has noticed that you now spend most of your time studying microbiology and has become curious about the subject. She asks you to explain in the simplest possible way how prokaryotes differ from eukaryotes. What do you tell her? 2.) In the advent of COVID-19, what physical method and chemical agent do you think is the most effective method in controlling the spread of the disease? Justify your answer.arrow_forwardWhy did Carl Woese propose the domain Archaea? The domain Bacteria already had too many organisms in its classification. The methanogens were discovered to be a complex organism, between prokaryotic bacteria and eukaryotes, thus it needed its own domain. He discovered that methanogens were too large to be classified as bacteria, but too small to be classified as Eukarya. In analyzing the rRNA of methanogens, he discovered that it was completely distinct from any other bacterial RRNA that had been studied. The DNA of methanogens was discovered to use different nucleotides than those of organisms in Eukarya or Bacteria.arrow_forward
- A scientist isolates a new species of prokaryote. He notes that the specimen is a bacillus with a lipid bilayer and cell wall that stains positive for peptidoglycan. Its circular chromosome replicates from a single origin of replication. Is the specimen most likely an Archaea, a Gram-positive bacterium, or a Gram-negative bacterium? How do you know?arrow_forwardCompare the digestive, respiratory and circulatory system of E coli bacteria and Cactus, then mention why the Eukaryotic species is more developed than the Prokaryotic one .arrow_forwardWhen do bacteria form endospores? a-when they get ready to reproduce b-when environmental conditions become unfavorable c-when they get ready to carry out conjugation d-when they carry out photosynthesisarrow_forward
