1.Have out your Notecard Sticker Sheet. Lay out your notecards (definition side up) on your desk 5x4 + 3, “Antibiotic” needs to be top left card. 2.Get Video HW from tray if you turned it in yesterday. Have out for Quiz. 3.LONG-write (write on notebook paper and turn in): Scientific research has led to a better understanding of how viral diseases replicate, and therefore to the discovery of new vaccines that help prevent the spread of viral diseases. How have these scientific advances most directly affected society? Answer in 75 words. – YOU HAVE 10 MINUTES ONLY!!! A2 computer HAPPY WEDNESDAY

Essential Question What effects do microorganisms have on other organisms and the environment? Standard 4C – compare the structures of viruses to cells, describe viral reproduction, and describe the role of viruses in causing diseases such as human immunodeficiency virus (HIV) and influenza. 11C – summarize the role of microorganisms in both maintaining and disrupting the health of both organisms and ecosystems.

Virus and Microorganisms Review Number your paper 1-20. Work with a partner to answer the questions.
7
1. What process is illustrated in the diagram? Lytic Cycle

2. Bluetongue virus causes severe disease in sheep and cattle. High levels of infection in livestock populations can threaten the livestock industry. Which of the following statements best describes how a bluetongue virus particle reproduces in its sheep or cattle host? A. The virus immediately kills the animal and then escapes to reproduce. B. The virus makes spores that are shed on the ground with the animal’s wastes. C. The virus uses the animal’s cellular machinery to reproduce inside the animal. D. The virus releases eggs into the nutrient-rich environment of the animal’s digestive tract.
9
3. Describe a difference between how viruses reproduce and how cells reproduce. Virus depends on a host cell, cells can reproduce asexually and sexually
10
4A. Label the following pictures as cells or viruses. Virus
11
4B. Label the following pictures as cells or viruses. Cell
12
4C. Label the following pictures as cells or viruses. Cell
13
4D. Label the following pictures as cells or viruses. Virus

5. 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.
15
6. Is the population pictured above of a bacterial or viral population? Bacterial because it states that it has antibiotic resistance
16
7. One student in a class becomes sick with a fever and cough. Two days later, three other students in the same class become sick with the same symptoms. This is evidence that the illness is most likely caused by — A. cold weather B. a pathogen C. a genetic mutation D. nutritional deficiencies
17
8. 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
18
9. Which viral reproduction cycle is pictured above? Lysogenic
19
10. T/F Viral nucleic acid replicates independently of the host cell chromosome in the Lysogenic cycle. False, they replicate together during the INTEGRATION phase of the lysogenic cycle
20
11. A photograph of a virus is shown below. The projections on the surface of this virus allow the virus to… Glycoprotein spike allow the virus to attach to the surface of cells
21
12. Cold sores are caused by the herpes simplex virus type 1. A company that wants to develop antiviral drugs would ask a research immunologist to study — A. the mechanism used by the virus to infect cells B. how closely related the virus is to cold viruses C. the metabolism of the virus D. meiosis in the virus
22
13. Viruses and cells are different in many ways. In which of these ways are viruses and cells most similar? Composition of outer covering Stages of life cycle Composition of genetic material Stages of reproduction
23
14. 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
24
15A. A retrovirus gets its name from the fact that when it infects a cell, a retrovirus uses ______ to produce _______. Which is the _______ of how transcription works. RNA DNAREVERSE
25
15B. _______is the most infamous retrovirus, and there is no cure. ______ works as a medicine to block this enzyme, _________________ _______________ from working. HIV AZT REVERSE TRANSCRIPTASE
26
16. Identify the biomolecules LIPID
27
17. Identify the biomolecules PROTEIN
28
18. Identify the biomolecules CARBOHYDRATE
29
19. Identify the biomolecules NUCLEIC ACID
30
20. Which biomolecule makes up the structure of a capsid? A D B C
