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.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
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.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
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 |

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?
