b.Explain the difference between enveloped and nonenveloped viruses.

c. Compare and contrast the viral replicative (lytic) vs. the lysogenic cycle.

d. Discuss the three hypotheses for the origin of viruses and explain how they continue to evolve.

13、It is claimed that employers are reluctant to hire women for some jobs because of their higher expected quit rates. Assuming women are more likely to quit, use human capital theory to explain what kind of jobs an employer would be especially reluctant to hire women for. Explain the reasons for the employer’s reluctance.

15、To the extent that it is true that women earn less because they spend less time in the labor market and that they spend less time in the labor market because they are paid less, how can this vicious circle be broken? Offer some suggestions and give examples.

The distinction between artificial selection and natural selection is important to master. Consider a bacteria that does not cause human disease. Describe these processes using illustrative examples. Your examples may be fictitious, but they need to be realistic and make biological sense.

[2 pts] Describe a specific example in which the bacteria changes (evolves) in a manner that illustrates artificial selection. Your description should contain an explanation.

Explain in a short paragraph and give examples

• How is intellectual property a true form of property? Do you think it is appropriate for governments to protect intellectual property just like any other form of property? Explain your answer.

Suppose that you are working as part of a team designing a network for XYZ high school. Consider that the school has six departments, Admin, Academic, Human Resource (HR), Finance, IT support and Sports.

1. Analyse the project hardware requirements along with the number of devices and cost. [3 Marks]

2. Justify the approach you would be taking to design the network for the school. [3 Marks]

3. Using the network simulator (such as packet tracer) design the network. [4 Marks]

4. Illustrate the network configuration you have used. [5 Marks]

You have isolated what appears to be an intracellular parasite from a blood culture from a human case of chronic fatigue syndrome in Chester County , Pennsylvania. Electron microscopic studies indicated that the isolate looks like a virus, but the results are not conclusive. Your virology/bacteriology training makes you believe that this isolate is either a new virus or a coxiella. Your virology professor tells you that your isolate is not a bacterium.. How would you go about to establish whether the new isolate is a virus or a bacterium? If it is a virus, name it, and explain the basis for your naming it this way.
