Solved in 2 steps
- Explain how the antibodies produced in response to a vaccine prevent SARS-CoV-2 infection.If you are infected with SARS-Cov-2, but have undetectable or low levels of antibodies a few months later, does this defintively indicate that you have zero immunity to SARS-CoV-2?describe the chain of events that leads to pneumonia in individuals infected with SARS-COV-2?
- please explain SARS-CoV-2 spreads through cell-to-cell transmissionSARS-CoV-2 is more contagious in humans than SARS because it has been shown that SARS-CoV-2 emerged from bats that were superspreaders. SARS-CoV-2 was derived from SARS by antigenic shift. There are more than 1 correct answers in the other choices if X number of SARS-CoV-2 particles would infect Y number of respiratory epithelial cells, higher (than X) number of SARS particles would be required to infect Y number of the same cells.Is the antigenic determinant reducing or non-reducing? reducing non-reducing both cannot be ascertained
- COVID-19 is caused by infection with a novel corona virus, SARS-CoV-2. Testing someone for active infection involves examining samples taken from the nasal mucosa for fragments of the virus. Another type of testing involves examining blood for the presence of antibodies that can bind to SARS-CoV-2. Use what you've learned about the immune system. What are the suggested reasons why someone would possess antibodies to SARS-CoV-2.Define antigenic shift, antigenic drift, and original antigenic sin.Explain why IgM has a stronger power of agglutination than antibodies of any other class.
