- Look at how different organisations are involved in limiting the spread of COVID-19. Choose a local, national and international organisation and evaluate the measures it has put into place to protect the spread of the disease. The Conservative government is an obvious one to do for national organisation. Compare what we have done compared to other countries to evaluate its effectiveness. As an international organisation I would probably do WHO and I will leave you to come up with your own local organisation.The H-precursor of ABO blood group system consists of proteins on to which sugar molecules are attached to. Which among the 4 sugar molecules given below is not present in the H-precursor of O-antigen Fucose N-acetyl glucosamine Galactose ON-acetyl galactosamine NextKinase and coagulase are important for bacterial infections because they enable bacteria to move deeper into tissue by means of a blood clot. What type of virulence factors are these two enzymes? O Incomplete phagocytes Extracellular enzymes O Antiphagocytic factors O Endotoxins MacBook Air 888 F7 esc 4 6. 3 Q E F A
- Match each of the descriptions in Column A with the correct panel listed in Column B. Description Panel Resistant bacteria share resistance genes with each other Resistant bacteria survive and reproduce Treatment with methicillin kills nonresistant bacteria Some bacteria carry a mutation that provided resistance to methicillin Predict the possible outcome(s) if the antibiotic tetracycline was applied after panel 4. Check all that apply. O The tetracycline will act as a selective pressure, causing bacteria to mutate in order to survive. O Since the population is resistant to methicillin and not tetracycline, none of the bacteria will survive. O Treatment with an antibiotic will not affect the overall survival of the population. Any bacterium that has a mutation for tetracycline resistance would be able to survive.Which of the following would be the most likely to act as a diphtheria antitoxin?
