From the given situations, explain whether its solution requires a qualitative analysis, quantitative analysis, characterization analysis, and/or fundamental analysis. More than one type of analysis can be applied for some problems.  1. The structure of a mutated coronavirus strain found in the Philippines needs to be determined.  2. The residents of a prominent subdivision in Iloilo near a waste disposal site are concerned that it is leaking contaminants into their groundwater.  3. The Iloilo Museum of Contemporary Art (ILOMOCA) is concerned that the recently acquired oil painting is not authentic.  4. The Iloilo International Airport needs more reliable scanner for detecting explosive materials in luggage.  5. An oil spill in Barrio Obrero last July 2020 leaked around 250,000 L of fuel reached the neighboring towns and the island of Guimaras.

Question 20 Medical microbiology laboratories are using molecular methods more and more to facilitate pathogen identification. What are the advantages of molecular methods, compared to traditional cultures? Question 20 options: a) Molecular methods provide rapid, quantitative results even for pathogens that have mutated b) Molecular methods are associated with increased sensitivity and yield rapid results c) Molecular methods are associated with increased sensitivity, and yield rapid results related to susceptibility testing d) Molecular methods yield results that remain positive for a long period of time, and are resistant to contamination with commensal organisms

What actions described in the video do you think are similar to the COVID-19 threat today and why? What efforts by the government or other officials actually made the 1918 pandemic worse? Are any of these same actions occurring today? What is most shocking to you about the events described in the video about the 1918 pandemic? Are any of those shocking events now occurring in a similar way in response to COVID-19?

Due to the lack of any antiviral for a newly emergent virus, blood harvested from individuals who were infected by the virus and subsequently fully recovered without hospitalization is in a clinical trial to treat individuals who are very sick by the virus. The donors have been carefully screened to eliminate their possibility as carriers (in their blood) of any virus. Which of the followings is the best strategy for this clinical trial:     generating sera from the donors' blood and injected them i.v. to the recipients whose blood types are matched to those of the donors     matching blood type of the donors and recipients before blood transfusion     generating sera from the donors' blood and injected them intravenously (i.v.) to the recipients without worrying about the matching of their blood types     there are more than 1 correct answers in the other choices

The epidemiological or disease triangle is a model of disease causation that proposes three factors contribute to an outbreak – an agent that causes the disease, a susceptible host, and an environment that brings the host and agent together. Some general changes within these three factors that may cause an infectious disease to emerge include:     A. changes in populations or behavior of reservoir hosts or intermediate hosts   B. microbial genetic mutation and viral genetic recombination or assortment    C. environmental factors such as an increase in precipitation   D. all of the above    E. none of the above

The nose swab PCR test for COVID-19 is an accurate and reliable test for diagnosing COVID-19. A positive test most likely means an individual has COVID-19. Whereas a negative test means an individual probably did not have COVID-19 at the time of the test. Please use what you have learned in this lab to justify this statement.

35.  There is a  mystery  and an unusual bacterial disease in Contra Costa County. Researchers as well as physicians  conclude that  it  must be controlled  before it  goes out of hand.  They also find that the pathogen has a extended generation time. What antibiotic do you suggest to use? Group of answer choices Rifamycin Penicillin Quinolones ( such as ciprofloxacillin) Tetracycline Sulfa drug and trimethoprim combination   36.   Which of the following best describes action of the ciprofloxacillin in prokaryotes ? Group of answer choices inhibits RNA polymerase, consequently no RNA synthesis in bacteria interferes with DNA replication by randomly nicking the DNA enhances DNA gyrase activity in killing UTI pathogens binds and modifies elongation factor ( ADP ribosylates) inhibits prokaryotic translation by binding to 50S subunits and arresting translocation inhibits DNA gyrase; prevents snapping back of the separated strands at replication fork

Please consider the figure attached  i. The ordinate (i.e., 'y-axis') represents values for the C or G nucleotide base proportion in sequences (or, in this case, genomes).ii. Influenza viruses that infected birds or moved from birds to humans without spreading are characterised by higher A + U content relative to influenza viruses that infected humans for long time periods.iii. Influenza viruses adapted to human hosts are characterised by lower G + C content relative to influenza viruses that infected birds or moved from birds to humans without spreading. iv. Human and swine influenza A H1N1 strains evolved from a birdlike G + C state to a humanlike G + C state since 1918. v. Data such as those depicted in the figure have been interpreted as evidence that the 1918 influenza virus strain originated from a bird influenza virus population.   Question 1 options:   A)  Statement ii conveys accurate information.   B)  Statements ii,…
