HAPPY FRIDAY MY NINJAS What you need: Writing Utensil, Journal and virus worksheets. Notecards are due today for a 50. If you have the extra credit video cornell notes, show me! Bellwork Today: Write and answer the question below: How are viruses different than bacteria? Explain in 20 words or more.  *Hint: use your notes. Also, remember that bacteria are cells. Also think about vaccines vs antibiotics

In your Journal Page: ______ Title : Virus vs. Bacteria EQ: How are viruses different from bacteria?

Jimmy Kimmel’s message Videos: How vaccines work Jimmy Kimmel’s message

You need to Remember: AntiBiotics are used to treat Bacterial infections Vaccines are used to prevent Viral infections

Do the following in Pencil!! Mark all viruses with a “V”. Mark all bacteria with a “B”. Label all of the DNA (genetic material). Label the lipid envelope (if it has one). Label the spikes (glycoproteins) if present. Label the protein capsid.

Circle all the viruses with a red color. Once you are sure you’ve labeled this correctly you may do the following. You will have 10 minutes. Circle all the viruses with a red color. Circle all the bacteria with a blue color. Color all of the DNA with a green color. Color the lipid envelope of any virus with an orange color. Color any spikes (glycoproteins) in purple. Trace any protein capsid brown.

Fold the document in half and glue into your journal (left side) You have 2 minutes

On the opposite page of your journal write “Review Questions”

1. Which of the following are viruses? B. A. D. C.

2. A tomato plant in a greenhouse was found to be infected with tobacco mosaic virus. A few weeks later, nearby plants were also found to be infected with the virus. Which of the following best describes how the virus reproduced? A. The virus made its own spores. B. The virus produced seeds in the tomatoes. C. The virus used the host plant’s resources and machinery to reproduce.  D. The virus immediately killed the host plant and was free to reproduce.

3. Is the population pictured above of a bacterial or viral population 3. Is the population pictured above of a bacterial or viral population? Explain.

4. Viruses are able to infect cells because they share a common genetic code and are able to use host cell enzymes to carry out protein synthesis. There are some structures which are unique to viruses and not found in cells. These include:  I. Protein capsid II. Nucleic acids III. Cell wall   A I only B II only C I and II only D II and III only

5. Which viral reproduction cycle is pictured above 5. Which viral reproduction cycle is pictured above? Explain how you know. Lysogenic: In this cycle the viral DNA is “integrated” into cells existing DNA and “waits”

6. Scientists are designing new medicines to fight infectious diseases caused by viruses. One of the most effective ways these medicines could limit the spread of the virus within the body would be to — A) prevent viruses from dividing B) burst cells infected with viruses C) stop viruses from attaching to cells D) make it easier for viruses to leave cells
