Do you think a variation in the human genome that confers resistance to coronaviruses (SARS-COV-2) Will be selected for in the human population through future human generations? why or why not? Consider covid 19 morality rates, the reproductive ages of those who are most at risk, economic factors, etc. Pathogens evolve over time as well, what effect if any could this have on human evolution?

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?

It’s late summer and a new influenza virus strain has appeared in chickens across the country.It’s an H1N1 strain of Influenza A, like the Spanish flu that caused one of the deadliest pandemics in humanhistory, back in 1918. In that case too it started as an avian flu that mutated and jumped directly from birdsto humans.You are a researcher at the NIH and the President gives you 24 hours to predict the chances that this couldturn into the next “Spanish flu”. They also ask you to present a plan for a vaccine that will specifically targetthis new strain.The full sequence of the Spanish flu virus is available and is also known which mutations where key toconfer it both high infectivity and high virulence. Also the frequency of mutations of this family of viruses isknown.Samples of the new strain currently infecting chickens are also available to you.You are at the NIH laboratories in Bethesda, MD, and you have infinite resources (equipment and staff) atyour disposal.Remember: Influenza…

Scientists often see that organisms with similar genetics are susceptible to being infected by similar viruses. This diagram shows genetic relationships between five species of rabbits. A particular virus commonly infects Sylvilagus bachmani.   Using the diagram, determine which other species would MOST LIKELY be at risk for infection by this virus? Question options:   Lepus callotis   Lepus insularis   Sylvilagus aquaticus   Sylvilagus audubonii

Corona-virus disease 2019 (COVID-19) is a new disease, caused by a novel (or new) corona-virus that has not previously been seen in humans. This virus can be a product of dark biotechnology?

Topic is SARS-CoV-2 Describe how mutations or genetic variation contributed to either: the evolution of your pathogen (or) the host’s chance of resisting the pathogen or surviving the infection If applicable, you can also discuss how genetic variation or mutation have made it difficult (or easy) to treat infection caused by your pathogen.

"Early in the COVID-19 pandemic, some argued that comparable numbers of people caught bad strains of the influenza virus (causing the viral flu); thus, by extension, the restrictions imposed on society for COVID-19 were unduly burdensome. Based on our discussion in class, which arguments could be made to refute this argument. "     "While an average of 31 million people catch the viral flu each year in the US (compared to 16 million COVID-19 cases so far), the mortality rate from the flu seems to be perhaps 8 to 24 times lower than for COVID-19."     "Fewer people have caught COVID-19 than catch the viral flu in a given year, but the comparison is not entirely fair since we are not restricting social gatherings or wearing masks during viral flu seasons. A fair comparison would be what would have happened with COVID-19 infections if normal year practices were carried out. "     More than twice the number of people in the US have caught COVID-19 than catch the flu virus in a…

In many viral diseases such as smallpox, and mumps, illness occurs shortly after exposure to the virus. In others such as, AIDS, the victim may not show any symptoms for many years. How would you explain the difference between the two situations>
