Evolutionary changes of antibiotic resistant bacteria increase the ability of a species to survive and reproduce under any circumstances (True or false) give explaination for answer?
Step by step
Solved in 2 steps
- Which statement about spontaneous generation is false? A. It addresses the formation of living cells from previously nonliving material. B. This was a common belief for during the Middle Ages. C. Pasteur demonstrated that it does not occur under normal laboratory conditions. D. It occurs every time a new species evolves from a preexisting species. E. It apparently occurred at least once – when life on Earth began.You are discussing the choice of the “oil-eating” bacteria that you will use to clean the affected area from the oil spill and your team wants to know whether the Kalba sea constitutes a natural habitat for these bacteria. Formulate a hypothesis stating why or why not the Kalba sea area can be considered a natural habitat for such bacteria. Support your answer by discussing the role of evolution in contributing to the survival and thriving of “oil-eating” bacteria. Explain how and why these bacteria acquired these characteristicsIn hospitals where many tuberculosis patients are treated the population of the tuberculosis mycobacteria may be constituted of multiresistant (to antibiotics) strains. How does the synthetic theory of evolution explain this fact?
- In patients with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. Explain how this could result in the evolution of drug-resistant pathogens.Evolution is one of the major unifying concepts of modem biology. Explain the mechanisms that lead to evolutionary change. Describe how scientists use each of the following as evidence for evolution. • Bacterial resistance to antibiotics • Comparative biochemistry • The fossil records (1000 words min)The media has recently reported that a high number of patients while staying in the hospital, are gettinginfections caused by antibiotic-resistant bacteria. Using evolutionary theory, explain how this could occur.
- In one paragraph, using your own words, explain the role that natural selection plays in the growth of antibiotic-resistant strands of bacteria.Science fiction movies have been known to sketch out a world of the near-future where terrible things have happened such as the evolution of antibiotic resistance in flesh-eating bacteria. What might we reasonably say about this topic? (Select all that apply) A - While one can have fun with entertaining stories about evolution (including ones that are very plausible), this is not a good reason to fund research on antibiotics because that is a solved medical problem. B - It has already happened with some early antibiotics (like penicillin)-the only reason we are momentarily okay is the continued development of additional antibiotics. C - In principle, it is possible but evolution takes millions of years, so don't expect it in the near-future. D - The bodies of humans have evolved since the discovery of antibiotics such that they are less and less effective already. E - We shouldn't find antibiotic resistance to be evidence for evolution because it is only a science-fiction story: it…Based on what you know about the mechanisms through which the effective antibiotics work, describe ways in which a population of coli resistant to these drugs could evolve. How does this relate to the theory of evolution by natural selection?
- The fact that a prokaryote has the ability to make a new protein that is placed in the cell membrane of the mesosome is important to the process of evolution because this represents a) the mutation of a gene, b) new DNA producing a new genetic variation, c) r RNA using a new type of m RNA, d) the species having a greater degree of genetic variability, e) all are trueHow well do you think bioremediation achieves the goal of cleaning up pollution?Support you answer with evidence about the success of genetic technology in manipulating bacterial characteristics, and historical facts about.Mycobacterium tuberculosis causes most cases of tuberculosis. Recently, strains of this bacterium that are resistant to all known antibiotic drugs have become increasingly common. Explain how this change occurred; use the terms mutation, DNA, and natural selection in your answer
