What information is provided by the numerical value of the Pearson correlation? Also in your own words, explain in detail and include a discussion of X, Y, co-variability and separate variability in your answer.

3. Explain in detail (200 words or less) how you would use the function(s) of the Core protein VII from the adenoviridae to develop or generate an antiviral therapy or treatment, describing why/how this treatment stops or limits virus lytic infection. (Note: You can not use an established antiviral therapy or treatment for your virus to answer this question.)

Figure 1. The hierarchical organisation of the protein tubulin. Individual molecular units (a) link together to form filaments (b), which assemble into microtubules (c).

Figure 1 illustrates the underlying structure of a microtubule, which was introduced in section 5.1 of the Block 3 book. The tubulin molecules provide binding sites for the energy carrying molecules GDP/GTP, which act in a similar way to ADP/ATP. The GDP/GTP molecules are shown in red on the diagram.

• a.Using examples based on the tubulin structure shown in Figure 1(a):
  • i.In a few sentences, explain what is meant by the terms ‘primary structure’ and ‘higher-order structure’ for a protein, and how they are related.

  • ii.Explain the importance of hydrogen bonding in the formation of higher-order structures. Include a simple diagram in your answer.

• b.The molecules GDP (guanosine diphosphate) and GTP (guanosine triphosphate) fulfil similar roles to ADP and ATP, as described in the Block 3 book.

  Explain the basic chemical difference between these molecules, and how this enables them to act as an energy transfer mechanism.

• c.Molecular motors carry cargo within living cells by ‘walking’ along microtubule tracks, at speeds of about 1-2 µm s^-1. If a small protein molecule has a diffusion constant of 0.5 x 10^-10 m² s^-1, estimate the time it would take to diffuse from one end of a 1 m long neuron to the other. Compare this with the time it would take a molecular motor walking along a microtubule track at 2 µm s^-1 to carry the protein the same distance. Express your answers in days (to the nearest day) and comment on your answer.

Please explain in detail.

Which of the following is true about market definition?
(a) The broader the market is defined, the more likely it is that two firms in that market will

(b) If two firms produce close substitutes, all else equal the Department of Justice will be less
likely to approve a merger between them
(c) Two firms producing complementary products will generally have their mergers approved
without incident, even without cost savings arising from the merger

Which of the following is true about price discrimination?
(a) Firms can increase their profits if they can selectively lower prices to consumers with a
lower willingness to pay
(b) Firms use coupons and other time-wasting devices as a way to get low types to “reveal”
themselves
(c) Firms are limited in the extent to which they can price discriminate by the possibility of
arbitrage
(d) All of the above

Which of the following is true about the Hotelling model with endogenouspricing and two firms located at the ends of a “city” one mile long?

(a) The location of the indifferent consumer is always at 0.5
(b) If the indifferent consumer is located at x ̃, then all consumers located to the left of x ̃ will be
indifferent too
(c) The Hotelling model was originally used to examine competition between hotels in the
1930s
(d) None of the above

Which of the following is true about entry deterrence?
(a) An incumbent monopolist will always try to block entry by a rival by increasing output
and lowering price
(b) An incumbent monopolist may not be able to block entry even if it wants to, especially if
the entrant’s fixed cost of entry is low
(c) An incumbent monopolist may try to block entry by a rival by lowering output and raising
price
(d) None of the above

Researchers conducted a study to find out if there is a difference in the use of eReaders by different age groups. Randomly selected participants were divided into two age groups. In the 16- to 29-year-old group, 7% of the 627 surveyed use eReaders, while 11% of the 2,314 participants 30 years old and older use eReaders. Use α = 0.05. For subscripts let 1 = 16- to 29-year-old users, and 2 = 30 years old and older users.

1. State the null hypothesis. H0: ___________

3. In words, state what your random variableP'1−P'2 represents.

4. State the distribution to use for the test. (Round your answers to four decimal places.)

5. Determine the test statistic using your data. (Round your answers to two decimal places.)

6. What is thep-value? (Round your answer to four decimal places.) Explain what thep-value means for this problem.

7. Draw a graph and label it appropriately. Shade the actual level of significance.

8. Do you or do you not reject the null hypothesis? Why?

9. Write a clear conclusion using a complete sentence.

In QuickBooks why would you use the payroll liabilities section? Plese explain

Why are satellites normally sent into orbit by firing them in an easterly direction? Based on this, explain why the International Space Station (ISS) orbits the Earth at about 17,500 miles per hour at an altitude above Earth’s surface of about 230 miles. Would it be more efficient to have a higher or lower orbit for the ISS? Explain in detail why or why not.

You and four friends have developed a new environmentally friendly heater. You all have extensive business experience. Together, you have established a new company, Green Heaters Pty Ltd ACN 512 302 XXX, which will manufacture and sell the new heater to wholesalers. The five of you will comprise the board of directors. The board has forecast that Green Heaters Pty Ltd will sell 650,000 heaters in the first year and will employ 100 staff.

You have been given the task of designing and developing the standard documentation which will be used by Green Heaters Pty Ltd. You must present details of your plans to the board of directors. Prepare a comprehensive report (5 pages) for the board members in which you explain what Green Heaters will do to manage the design and development of business documents. The report must explain details of the methods and processes you will use to produce high quality documents.

In the report, you should provide details of the types of documents which you will produce and how you will ensure that they will be suitable for requirements. You should explain the methods you will use to develop standard documents including templates and macros and provide information about any assistance you will need, including details of external sources.

Your report should detail the strategies you will use to ensure employees use standard documents productively. Provide information about the proposed organisational policies and procedures which will be implemented to govern the use of standard documents as well as ensure standard documents meet any changing requirements of the organisation in the short and long term. It must include prototypes of at least five documents, together with a sample of the written instructions which could be provided to employees who will use those documents.(in 300-350 words)
