Assume you are studying the infection dynamics between a species of spider and a species of ringworm that infects the spider. You sequence the genomes of each species for 30 years and find that each of these species has evolved adaptations. Specifically, the spider has evolved immune system adaptations to remove the ringworm and the ringworm has evolved counter-adaptations to evade the spider's immune system. Surprisingly, you find that the ability of the ringworm to infect the spider has not changed over 30 years. The finding that infectiousness has not changed in 30 years would be in support of which of the following?

In a recent influenza epidemic, physicians were utilizing a rapid diagnostic test to determine which patients were infected with influenza type A, type B, or not infected with influenza virus. Such a test was not available in the massive 1918 outbreak that killed millions of people around the globe. How might the availability of such a test have impacted that outbreak, and why?
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?
Suppose that a time machine allows you to go back in time (and to travel to Australia), and you have collected rabbits and Myxoma from the years 1955 and 1980. Once you are back in the twenty-first century, you infect both sets of rabbits with both sets of Myxoma viruses. The most likely result will be (1) that the rabbits from 1955 injected with the 1955 virus will have a _______ survival rate than those same rabbits injected with the 1980 virus; and (2) that the rabbits from 1955 injected with the 1980 virus will have a _______ survival rate than rabbits from 1980 injected with the 1980 virus. A. lower; lower B. lower; higher C. higher; lower D. higher; higher E. the survival rates will be the same in experiments (1) and (2)
If you suspected that heterozygous carriers of a particular disease gene had a selective advantage in resisting a type of infection, how would you go about testing that hypothesis?
Some advocate stockpiling the drug Tamiflu in the event of an influenza pandemic. Others point out that wealthy, Western nations would have an unfair advantage because developing nations (where the pandemic is most likely to start) would not have access to this expensive antiviral. Furthermore, some fear that indiscriminate use of the drug would promote the evolution of resistant flu strains. Given these caveats, do you think developed nations should stockpile Tamiflu for the protection and treatment of their citizens? Explain your answer
Viruses are considered non-living microbes, and yet they are responsible for many major disease outbreaks in humans, animals, and even plants. Consider the following: How are these non-living microbes able to reproduce without metabolic functions? Can viruses be exploited to help humans fight bacterial pathogens? Which viruses are able to stay dormant in the human body and reactivate later in life or when immune defenses are compromised? What impact might travel outside of the United States have in blood, tissue, or organ donation? Please answer question 1, 2, 3, and 4 if possible, thank you.

In a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 100, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 15,000. Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium? Group of answer choices There is no way to know given the information provided Both infections are equally likely Parasiticum mucoides Donoteatum thisbacterium
If viruses are not living, how come they adapt to their environment, replicate and cause infection?In the time of Covid-19 pandemic, explain how social distancing works to control the spread of viruses?
Imagine that you are a student in Alfred Hershey and Martha Chase’s lab in the late 1940s. You are given five test tubes containing E. Coli bacteria infected with T2 bacteriophages that have been labeled with either 32P or 35S. Unfortunately, you forget to mark the tubes and are now uncertain about which tubes is which. You performed their blender experiment and got the following results. Which tube out of these 5 contains E. Coli infected with 32P-labeled phage? Explain your answer.
How might an RNA-based genome result in an increased infection rate? What are some potential complications to this infection strategy?
In 2006, the US Food and Drug Administration (FDA) approved the use of bacteriophage preparation that can be used on ready-to-eat meat and poultry products to kill Listeria monocytogenes, a bacterium that causes listeriosis. Some people may have concerns about the use of phages in foods. From what you have learned about bacteriophages and viruses, why do you think we do not have to be concerned about the presence of bacteriophages in food?
