• Bacteria is nonliving

• Bacteria is living

Multiple Select

Viruses can reproduce independently (on their own).

• True

• False

Multiple Choice

Do viruses have genetic material (DNA)?

• no

• yes

Multiple Choice

Does bacteria have genetic material (DNA)?

• no

• yes

Multiple Choice

What does the word "metabolism" mean?

• The ability to convert food into energy

• Not this answer

Multiple Choice

Can viruses (which are nonliving) convert food into energy?

• Yes

• No

Multiple Choice

Now that you have answered all of those questions, answer the original question...

What do viruses and bacteria both have?

• Capsids

• DNA/RNA

Multiple Choice

Now that you have answered all of those questions, answer the original question...

What ONLY applies to bacteria?

• Uses a host to reproduce

• Reproduces independently

Question 2: The following was a question on your exam. Read over it and complete the next few slides.

Multiple Choice

What does disrupt mean?

• Make better

• Mess it up

• Leave it alone

Multiple Choice

What is a cellular process?

• Another name for Biology

• Steps to destroys cancer

• Anything a cell does such as make ATP

Multiple Choice

How does a virus cause disease?

• It latches onto any object and begins to eat away at it.

• It attaches to a cell, inserts its DNA, makes copies of itself using cell parts, and then lyses.

• It becomes part of a cell and replaces the organelles with cancer substances.

• It attaches to bacteria in order to create an infection in the body.

Multiple Choice

What does "machinery" mean?

• Parts

• Not this answer

Multiple Choice

What are antibodies?

• Antibodies are released by your own immune system in order to fight off viruses or bacteria.

• Antibodies are released by viruses.

Multiple Choice

Now that you have answered all those questions, answer the original question.

Which statement BEST describes how viruses disrupt normal cellular processes to cause disease?

• Viruses release antibodies that destroy the cell membrane so more viral particles can be released. 

• Viruses use machinery to build products the virus needs.

• Viruses release large amounts of energy into the cell, causing increased growth rates. 

• Viruses block gene expression and prevent host cell DNA replication.

Question 3: The following was a question on your exam. Read over it and complete the next few slides.

Which one of these scenarios accurately depicts the transfer of a virus from one organism to another organism? (pick 2)

Multiple Select

What are ways to get viruses (select 3)

• Through the air

• Through space

• Through contact

• Through fluids

Multiple Choice

What must a virus rely on in order to replicate?

• Another living organism

• Anything it lands on

• The air

• Rocks

Multiple Choice

If a virus is NOT attached to a living cell, can it replicate?

• NO

• YES

Multiple Select

Based on the questions you just answered, answer the original question.

Which one of theses scenarios accurately depicts the transfer of a virus from one organism to another organism? (pick 2)

• A virus infects a rock as its host cell.

• A microscopic mite infected with rose rosette disease transfers the virus from plant to plant.

• An infected pig with a dormant virus sneezes, and the droplets in the air infect the farmer.

• A virus in the air replicates with gas molecules.

Question 4: The following was a question on your exam. Read over it and complete the next few slides.

Carlos attended a party where pizza was left out on the counter for several hours. Carlos was infected with a virus and sneezed and coughed multiple times while at the party. His friend Sarah continued to eat the pizza. A few days later, Sarah became sick with the same virus.

Explain the three main steps the virus took to infect Sarah’s cells and cause her to become ill.

Multiple Choice

Can the virus replicate on the pizza?

• No, pizza is nonliving

• Yes, as long as it is attached to something.

Multiple Choice

The question says "Explain the three main steps the virus took to infect Sarah’s cells and cause her to become ill." What is the main concept the question is trying to ask?

• Why Sarah was at the party?

• What is happening on the pizza?

• How do viruses replicate?

Multiple Choice

What is the first step for the virus to do?

• Lyse

• Inject its DNA/RNA into the cell

• Make copies

• Attach to a cell

Multiple Choice

What is the second step for the virus to do?

• Lyse

• Inject its DNA/RNA into the cell

• Make copies

• Attach to a cell

Multiple Choice

What is the third step for the virus to do?

• Become a cell

• Inject its DNA/RNA into the cell

• Make copies/Lyse

• Attach to a cell

Explain the three main steps the virus took to infect Sarah’s cells and cause her to become ill.

Question 5: The following was a question on your exam. Read over it and complete the next few slides.

In the late 1700s Edward Jenner developed the first vaccine from cowpox, an infectious virus found in cows. How do viruses, like the one of cowpox, cause disease?

Multiple Choice

Based on everything you have answered so far, what should be the answer to the question: In the late 1700s Edward Jenner developed the first vaccine from cowpox, an infectious virus found in cows. How do viruses, like the one of cowpox, cause disease?

• By gaining energy from metabolizing their food.

  
  

• By replicating inside the cell and then lysing the cell.

  
  

• By competing for water with cells of the infected organism.

  
  

• By sexually reproducing with other viruses in the environment.
