Why are viruses NOT considered to be alive? Use NASA's definition of life to explain why viruses are not considered to be alive?
1. What is the primary function of the RNA genome in coronaviruses?
In humans, SARS CoV-2 viruses infect ONLY respiratory cells (nose/throat/lungs)?
From the video above, true or false? The virus contains additional proteins called "nucleoproteins" that help the virus replicate inside the host cell.
Match the viral structures with their correct labels
Match the viral functions with their correct labels
What is a viral capsid?
What is the function of the viral envelope?
A virus connecting to the host cell membrane by its spike protein connecting to a host cell membrane receptor is called?
What occurs during viral replication and assembly?
Match the process with its correct definition.

Viral attachment | arrow_right_alt | virus hijacks cell's enzymes to copy its RNA/DNA and making of new virus particles in host cell |
Viral Replication and Assembly | arrow_right_alt | Virus leaving the host cell by either burst the host cell membrane or budding from its membrane |
Viral Exit and Transmission | arrow_right_alt | Virus connecting to the host cell membrane using its proteins that match with host cell receptor proteins |
Link each term to its proper definition.

Capsid | arrow_right_alt | a manufactured "drug" triggering immune response to certain infections without making the host sick (or as sick) |
Viral Envelope | arrow_right_alt | Protein coat shielding the viral genome |
Vaccine | arrow_right_alt | Protective membrane from host cell surrounding some viruses |
Watch this video - note SARS CoV-2 does spread well by touch or surfaces. SARS CoV-2 is different from other coronaviruses in that it ...
From the above video.... What important process needs to happen in the alveoli that allows you to "breathe"?
From the above video ... What are the macrophages supposed to do?
From the above video .... If too many immune cells start to fight the virus, what can happen to the alveoli?
From the above video .... What ends up killing most people who die from COVID-19?
Watch this video, then answer the question
A. What is a zoonotic disease?
B. What is causing more zoonotic diseased to jump to humans (3 reasons)?
What is herd immunity?
Why is immunizing a certain percentage of a population important for herd immunity?
What happens if the percentage of immune individuals in a population drops below the herd immunity threshold?
Explain which of these 2 images most likely represent "herd immunity threshold" where enough people in a population have been vaccinated to that people who are not vaccinated are protected?
Image B
Watch this video then summarize in your own words how mRNA vaccines work. Use the words antigen and antibody in your answer.
COVID-19 mRNA vaccine - go to this link to see an image of the vaccine. Remember this is the vaccine and NOT the virus. The inside light purple strands represent copies of . The light purple strands are copies of of the spike protein and then "teach" other immune cells to recognize the COVID-19 spike protein as. This will allow the immune system to "remember" the spike protein and respond if the person gets infected with the SARS CoV-2 virus.
Watch this video about the scientists who won the Nobel Prize for the development of an mRNA vaccine for COVID-19. Create a list of your 3 most important things you learned from this video
Why are viruses considered "obligate intracellular parasites"? Make sure you consider all 3 parts of the definition!
