part b: Describe how bacteriophages and animal viruses may have evolved (Under the progressive hypothesis) part c; How is the egress of new virus particles different for an enveloped virus versus a non-enveloped virus? Explain each process part d: What is receptor-mediated endocytosis and how is it involved in virus entry? part e: How do plant viruses overcome the barrier of the cellulose wall and cuticle of plant cells in order to infect? part f: Compare the entry into host cells of enveloped and non-enveloped viruses

There are a number of studies which show that women engage in more private religious rituals and daily prayer than men, who tend to engage in more public religious rituals. A researcher would like to discover if there is a relationship between gender and religious type, that is extrinsically religious (publicly religious), intrinsically religious (personally religious) or nonreligious. Perform the appropriate test (α = 0.05)

Male extrinsic 9

Female extrinsic 9

Male intrinsic 14

Female intrinsic 16

Male non religious 12

Female non religious 6

A widget company tested 101,000 widgets, of which only 1,000 had defects. The company’s test correctly identified defects 99% of the time and correctly identified non-defects 95% of the time. 2 (a) What percentage of the widgets marked as defects were actually defective? (b) What percentage of the widgets marked as non-defects were not defective? (c) The answer to problem a is counter-intuitive. Explain what happened? (d) What would be your suggestion for improving the accuracy of the defect/nondefect identification. Improving the accuracy of the tests is not a valid answer.

A 25-year, $1,000 par value bond has an 8.5% annual payment coupon. The bond currently sells for $1,150. If the yield to maturity remains at its current rate, default risk is zero, and the bond is non-callable, what are the expected current and capital gains yields?A 25-year, $1,000 par value bond has an 8.5% annual payment coupon.

1. We want to test to see whether average SAT scores for science majors equals the average SAT scores for non-science majors. We collect the following sample SAT scores:

Science            Non-Science

440                  1000

1550                1010

1400                970

370                  1020

600                  980

800                  1000

1390                1080

1100   

1500   

1480

Use Excel to test this hypothesis at the 0.05 level by first testing variances (at the 0.05 level) and then means. Submit your Excel file along with your explanation.

Identify the appropriate statistical test for each research description:

1. Single-sample z-test

2. Single-samplet-test

3. Independent samples t-test

4. Related samples t-test (repeated measures or matched samples)

5. Correlation

A researcher investigates whether single people who own pets are generally happier than singles without pets. A group of non-pet owners is compared to pet owners using a mood inventory. The pet owners are matched one to one with the non-pet owners for income, number of close friendships, and general health.

You are in charge of pricing tickets for an upcoming event at the outdoor amphitheater where all seating is by general admission(no assigned seats). Demand for the event can be segmented into students and non-students. Student demand is Qst=10,000-100P. Non- student demand can be expressed as Qns=5000-10P. Your marginal cost per attendee is $10 and is constant. The capacity of the amphitheater is 5000. Since you can check for a student ID, you can charge each group a different price. What price do you charge each group?

Given the following sequence: LHYEAIAKAWNDAF

a. Classify each amino acid into polar, non-polar, & charged (at pH 7.0)–put a letter above each to show if polar (p), non-polar (n), or charged (c).

b.What are the ionizable groups?

c.What is the order of the pKaʼs going from low to high pH

d.What is the isoelectric point (pl) of this peptide?

e.At the pHʼs of 3, 6, & 9, what is the charge state?

f.What type of secondary structure would this peptide take and why?

g.How long would it be?

h.How many hydrogen bonds, at maximum
