- Describe the natural history of the Rabies (taxon:11292) : host infectivity, transmission, symptomology Describe the genomic structure of the Rabies (taxon:11292)virus Baltimore Classification of Viruses What is the genome made of? What are the genes? How are they organized? Is the genome single stranded, double stranded, RNA, DNA and what does it mean to be + or - strand? Is it segmented and what does that mean?what are the key contributors to and consequences of viral genome evolution, and why do RNA viruses evolve faster than DNA viruses?Why is conservation biology relevant to human coronavirus diseases? Because habitat destruction increases the transmission of zoonotic diseases from animals to humans. Because habitat destruction makes bats more aggressive Because habitat destruction increases the severity of coronavirus infections in bats. Because habitat destruction increases the rate at which coronaviruses mutate. Because habitat destruction increases the abundance of bat species.
- Why is it a strong evolutionary hypothesis that although viruses are the structurally simplest beings they were not the first living beings?what's the reason behind evolution of RNA virus recombination?What cells does HIV infect? Explain how HIV enters these cells HIV is a retrovirus. What do retroviruses do once they have entered a host cell? Why is there little to no immune response following infection by HIV? Why is it difficult to diagnose? What is the difference between HIV and AIDS? How does HIV lead to AIDS? How is HIV transmitted? There isn't a drug to cure HIV although drugs are used to keep the viral load low to prevent regression into AIDS. Explain how these drugs work.
- 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 O D. higher; higher E. the survival rates will be the same in experiments (1) and (2)What is the Coronavirus? Is it a living organism? How does it reproduce? The current vaccines that are being distributed in the United States are made by Pfizer, Moderna, and Johnson and Johnson.

Will things immediately go back to the way they were before? What is the Delta variant and how is it impeding on getting things back to "normal"?What are retroviruses? How do they reproduce and what is the role of the enzyme reverse transcriptase?
- Why do viruses more often evolve to greater transmission at the cost of virulence? From an evolutionary perspective why does this make sense?Why do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that? Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually very host specific. Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. dsDNA viruses aren't very transmissible and even when they are, they're not deadly. We already have effective vaccines for Herpes. Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited.This table lists three hypothetical versions of the spike protein gene in the coronavirus. The B version is the original version in bats; the H and N versions have mutations. The last two columns show the characteristics of the spike protein for each version of the spike protein gene. Version of the Spike Protein Gene B H N H ΟΝ O B B and N OH and B Spike protein can bind to molecules on the surface of ON and H Bat Cells Yes Which version of the spike protein gene will result in a spike protein that will allows a coronavirus to enter a human cell to reproduced by the cell? No No Human Cells No Yes No
