Why are viruses NOT considered to be alive? Use NASA's definition of life to explain why viruses are not considered to be alive?

Required

1

1. What is the primary function of the RNA genome in coronaviruses?

To protect the virus from the host's immune system

To act as a instructions for making more viral proteins

-To help the virus penetrate host cells

To maintain the virus's structure

Required

1

In humans, SARS CoV-2 viruses infect ONLY respiratory cells (nose/throat/lungs)?

True

False

Required

1

From the video above, true or false? The virus contains additional proteins called "nucleoproteins" that help the virus replicate inside the host cell.

true

false

Required

4

Match the viral structures with their correct labels

What is a viral capsid?

Invasion and multiplication of a virus in a host organism

Outer membrane surrounding some viruses

Infectious agent that replicates inside a host cell

The protein coat that protects a virus genome

Required

1

What is the function of the viral envelope?

It is a protein coat protects the virus genome

It is the invasion and replication of a virus

The process of how a virus leaves host cell

It is a protective outer membrane that was torn from the previous host cell

Required

7

A virus connecting to the host cell membrane by its spike protein connecting to a host cell membrane receptor is called?

viral exit and transmission

viral attachment

genome

viral replication and assembly

Required

1

What occurs during viral replication and assembly?

Virus copies its RNA/DNA, proteins and assembles new virus particles

Virus surrounds itself with a protein coat

Virus leaves host cell and infects others

Virus invades and multiplies in host organism

Required

3

Match the process with its correct definition.

Draggable item		Corresponding Item
Viral attachment		virus hijacks cell's enzymes to copy its RNA/DNA and making of new virus particles in host cell
Viral Replication and Assembly		Virus leaving the host cell by either burst the host cell membrane or budding from its membrane
Viral Exit and Transmission		Virus connecting to the host cell membrane using its proteins that match with host cell receptor proteins

Required

3

Link each term to its proper definition.

Draggable item		Corresponding Item
Capsid		a manufactured "drug" triggering immune response to certain infections without making the host sick (or as sick)
Viral Envelope		Protein coat shielding the viral genome
Vaccine		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 ...

can only infect cells in the upper part of your respiratory system

can infect cells all the way down deep into your lungs, tiny air sacs called alveoli

Required

3

From the above video.... What important process needs to happen in the alveoli that allows you to "breathe"?

Required

1

From the above video ... What are the macrophages supposed to do?

help the virus replicate 

create an environment in the alveoli that stop the virus from replicating

destroy the virus by engulfing it

1

From the above video .... If too many immune cells start to fight the virus, what can happen to the alveoli?

their thin cell walls can become damaged allowing fluid to leak in

the alveoli may explode

the alveoli may shrink in size so gases cannot be exchanged

3

From the above video .... What ends up killing most people who die from COVID-19?

the virus infecting the tiny fragile air sacs called alveoli

the immune system ignoring or not responding to the infection

the immune system's "explosive response" to the infection causing damage to the walls of the alveoli

ARDS - acute respiratory distress syndrome - the inability to breathe because fluid has leaked into the lungs

Required

0

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)?

Required

1

What is herd immunity?

the percentage of the population that can get infected

the percentage of the population that must be vaccinated so that the virus cannot spread to unvaccinated people

the percentage of the population that was infected but then recovered

Required

1

Why is immunizing a certain percentage of a population important for herd immunity?

it creates protection for those who cannot be vaccinated by stopping the infection from spreading

It makes everyone immune

It completely eradicates the virus

It educates everyone's immune system so they virus cannot infect anyone

Required

1

What happens if the percentage of immune individuals in a population drops below the herd immunity threshold?

Only the vaccinated individuals remain immune

No effect

The disease may spread more quickly and create an epidemic

The herd immunity threshold increases

Required

3

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 A

Image B

Required

3

Watch this video then summarize in your own words how mRNA vaccines work. Use the words antigen and antibody in your answer.

Required

4

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.

Required

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
