- Which of the following does NOT describe a mechanism of antibiotic resistance among bacteria? enzymes to hydrolyze or chemically alter the antibiotics mutations in target molecules so that antibiotics can no longer bind efflux pumps cell wall diffusion barrier, e.g. Gram-negative outer membrane, Acid Fast cell wall of Mycobacterium O increased synthesis of porins to increase antibiotic diffusion across membranesarrow_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_forwardThe table below shows the symptoms of some diseases that are caused by bacteria. Disease Symptoms vomiting, abdominal pain, coughing, muscular weakness, visual disturbance botulism inflammation of lungs, fever, shortness of breath, fluid in lungs pneumonia typhoid fever red rashes, high fever, intestinal bleeding tetanus uncontrolled contractions of voluntary muscles Which two diseases listed in the table affect the digestive system?

- What are the flaws ? Prokaryotes can live in many different environments. Anerobic organisms need oxygen to survive, while aerobic organisms can survive without oxygen. Autotrophs are organisms that can assemble high energy macromolecules for their energy. Chemotrophs are organisms that capture energy from light. Extremophiles are organisms that grow in extreme conditions like boiling water. Gram-positive bacteria have few layers of peptidoglycan, while gram-negative bacteria have many layers of peptidoglycan and are surrounded by an outer membrane. Harmful bacteria can cause illness like food poisoning. Helpful bacteria can be used in food production to make yogurt. The endosymbiotic theory states that some of the organelles in eukaryotes were once free living prokaryotes. This is supported by the mitochondria and cytoplasm since they have their own DNA and ribosomes. Harmful protists can cause diseases like malaria in humans and downy mildew in plants. Helpful protists can be…arrow_forwardconsider 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?

- Some bacteria possess antibiotic resistance, as well as the ability to survive through adverse conditions. Where in this type of bacteria is the DNA located? fimbriae, nucleoid, and endospore plasmids, nucleoid, and endospore nucleoid, fimbriae, and plasmids endospore, fimbriae, and plasmidsarrow_forwardFor a bacterial exotoxin with a typical A-B type toxin structure, removal of the A portion of the toxin would result in which of the following? The B portion remaining would still be able to bind to the target cell, but would not have toxic effects The remaining B portion would enter the cell and carry out its toxic activity, such as ADP-ribosylation The remaining B portion would cause inhibition of protein synthesis Nothing would happen because the A portion is responsible for binding to the target cell. The remaining B portion would still induce cell lysis Please answer asap and in short and content should not be palgarised pleasearrow_forwardA) A bacterium that has an F plasmid is able to do which of the following?

- The most selectively toxic antibacterial agents are those that interfere with bacterial cell wall synthesis. This is because ________. Group of answer choices bacterial cell wall synthesis is easily inhibited whereas eukaryotic cell wall synthesis is more resistant to the actions of the drugs bacterial cell walls have a unique structure not found in eukaryotic host cells eukaryotic cells do not take up the drugs eukaryotic cells inactivate the drugs before they can do any damagearrow_forwardBeneficial prokaryotes commonly found in food are in which domain?

The bacteria could not be grown in the researcher's laboratories, nor were any of them ever observed via and kind of microscopy. If they couldn't culture them or see them, how could the researchers know they discovered a new species? If they couldn't examine the cells for the presence of a nucleus, how did they determine that the organisms were prokaryotes and not eukaryotes?arrow_forward
