- In terms of microbial pathogenicity, molecular Koch's postulates are a set of experimental criteria that show: A microbe is the aetiological agent of a disease A gene encodes a product that contributes to disease A gene encodes a product that contributes to immunity to a disease A mutation does not contribute to diseasearrow_forwardGive typing answer with explanation and conclusion to all parts Antibiotics selectively inhibit or kill bacterial cells. Describe three targets of antibiotics in bacterial cells. Explain how the antibiotics produce these effects at each target. Bacteria have evolved mechanisms of resistance to many antibiotics. Describe two different mechanisms of resistance, explaining how the bacterium overcomes the action of the antibiotic. Give an example of an antibiotic whose effect can be overcome by each of the mechanisms you have described.arrow_forwardThe following graph shows the trends in bacteria and viruses after they infect an organism. A B Time Time 02017 Panon Eacatn, ine. Part A: Explain how reproductive differences between these two pathogens attribute to the differences shown in the graph. Identify whether viruses are organisms and describe how this graph supports your claim. Part B: Most antibiotics target the cell wall of a pathogen. Use the graph to explain why antibiotics can be ineffective against some pathogens. Number of bacteria- Number of viruses →arrow_forward
- Which statements describe ways in which antibiotic resistant bacteria can spread? Health care workers become infected after have interacting with sick patients. Hospital visitors transfer resistant bacteria from patients to family or community members. Animals raised for meat or milk are routinely given antibiotics. Animal feces is used as a fertilizer for food crops. Antibacterial soaps are used at home, at schools, and in hospitals.arrow_forwardGive typing answer with explanation and conclusion to all parts Which of the following factors contributes to the rise of antibiotic resistance? SELECT ALL THAT APPLY intron removal spontaneous mutations selective pressure induced mutations horizontal gene transferarrow_forwardThe following graph shows the trends in bacteria and viruses after they infect an organism. Time Time 2017 Pearon Education, Inc. Part A: Explain how reproductive differences between these two pathogens attribute to the differences shown in the graph. Identify whether viruses are organisms and describe how this graph supports your claim. Part B: Most antibiotics target the cell wall of a pathogen. Use the graph to explain why antibiotics can be ineffective against some pathogens. B IU 1000 acer Number of bacteria> Number of virusesarrow_forward
- You will have the opportunity to explore the effectiveness of six different antibacterial substances against a certain species of bacteria. You will follow scientific procedures by questioning, forming a hypothesis, setting up and conducting an experiment, analyzing results, and forming a conclusion. You will determine the comparative effectiveness of six antibiotics. What is the dependent variable? What is the independent variable?arrow_forwardBacteria have three major methods of resisting antibiotics. They may lack (or modify) the feature that the antibiotic targets, so that the drug has little or no effect. The may have an enzyme that helps them break down and inactivate the antibiotic. They may have efflux pumps that remove the drug from the cell. Which method of resistance are Gram-negatives particularly famous for? Group of answer choices target modification enzymatic breakdown horizontal transfer efflux pumpsarrow_forwardIn a minimum of 5 sentences,explain "Biodivesity starts in the distant past and it points toward the future".arrow_forward
- consider the following terms: Envelope Fusion Gene therapy Pathogen Vaccine Capsule Decomposer Epidemic Mold Spore Yeast Choose 2 terms from the list and answer the following questions for each term: What familiarity and prior knowledge do you have about the term? What does the term mean in everyday language to everyday people? Use examples to help describe your thoughts. How do people use the word? What does the term mean in technical language to biologists? How is the term related to the course student learning outcome: Describe classifications of biological diversity? What are the similarities and differences between the everyday and technical meanings and uses of the term? What impact might the similarities and differences have on your learning of biology concepts in this course?arrow_forwardWhat is the difference between a probiotic and prebiotic? Group of answer choices Prebiotics are natural chemicals present in food, whereas probiotics are artificial chemicals added to food to improve their nutritional value Prebiotics are living microbes that transform food, whereas probiotics are microbes grown in the lab and added to food. A prebiotic is a microbe acquired before birth, whereas a probiotic is a microbe acquired after birth A prebiotic serves as food for probiotics, which are consumable live microbes with health benefitsarrow_forwardThe following graph shows the trends in bacteria and viruses after they infect an organism. Part A: Explain how reproductive differences between these two pathogens attribute to the differences shown in the graph. Identify whether viruses are organisms and describe how this graph supports your claim. Part B: Most antibiotics target the cell wall of a pathogen.
