9. The process of DNA replication creates a particular problem for replicating the ends of linear chromosomes.
a) Describe why the DNA replication machinery has difficulty replicating DNA ends.

b) Telomerase has been identified as an enzyme that can reverse the outcome of end replication.
Describe the near-universal mammalian chromosome telomere sequence and how telomerase solves the problem of end replication.

Astronomy:

6.What is a brown dwarf? Is it different from a proto-star? How?

7. What different types of gas do astronomers find in the interstellar medium?

8. Astronomers believe the Sun formed with other stars near the Orion Nebula. If that is true, why is the Sun here and not there?

9. Astronomers can tell the age of a star by the age of its cluster. How is this determined?

An extremely thin sheet of glass is being inspected at the factory. Illuminated by white light at near-normal incidence, the film-like sheet is 0.402 µm thick and has air on both sides. If the glass has a refractive index of 1.52, what wavelength of visible light (in nm) does it reflect most strongly? (The wavelengths of visible light range from 400 to 700 nm.)

A manufacturing firm is planning to open a new factory. There are four countries under consideration: USA, Canada, Mexico, and Panama. The table below lists the fixed costs and variable costs for each site. The product is mainly sold in the U.S. for $995 per unit.

Location                  Fixed Cost      Variable cost

USA                          $1,000,000             $210

Mexico                     $550,000                $250

Canada                      $700,000                $230

Panama                      $ 450,000               $300

a- Using cross-over analysis, find the range of production that makes each country optimal with lowest total cost.

b- Using Excel, construct total production cost linear graph for all 4 locations and verify cross-over points obtained in part (a). In your graph, use quantity values from 0 to 20,000 at increments of 500.

c- If the company forecasts that market demand will be around 17,000 per year, which country is the best choice and what is the yearly profit?

d- Construct Total cost, Total revenue, and Total profit graphs for the optimal location in part C. In your graph, use quantity values from 0 to 20,000 at increments of 500.

Shirley, a recent college​ graduate, excitedly described to her older sister the ​$1,670 ​sofa, table, and chairs she found today.​ However, when asked she could not tell her sister which interest calculation method was to be used on her​ credit-based purchase. Calculate the monthly payments and total cost for a bank loan assuming a​ one-year repayment period and 14.5 percent interest. Now assume the store uses the​ add-on method of interest calculation. Calculate the monthly payment and total cost with a​ one-year repayment period and 12.5 percent interest. Explain why the bank payment and total cost are lower even though the stated interest rate is higher. The monthly payment for a bank loan assuming​ one-year repayment period and 14.5 percent interest is ​$? The total cost for a bank loan assuming​ one-year repayment period and 14.5 percent interest is ​$? If the store uses the​ add-on method of interest​ calculation, the monthly payment with a​ one-year repayment period and 12.5 percent interest is ​$? If the store uses the​ add-on method of interest​ calculation, the total cost with a​ one-year repayment period and 12.5 percent interest is $?

5. You are preparing a project to lay fiber optic cable. The first task is to mobilize the team. You estimate this will take one week and cost $4000. The second task is to lay the cable. This will take three weeks and will cost $30,000. The total length of the cable is 15 miles. The last task, which will take one week, is to terminate and test the cable. You budget $6000 for this. At the end of the first week, you have completed mobilization, but it cost a total of $4500. At the end of the third week, you have completed five miles of cable at a total cost of $28,000 (installation only). It takes you a total of 10 weeks to complete the entire project, for a total cost of $75,000.

a. At the end of week 1: i. What is your SPI? ii. What is your CPI? iii. What is your EAC?

b. At the end of week 3: i. What is your SPI? ii. What is your CPI? iii. What is your EAC?

c. At the end of the project: i. What is your SPI? ii. What is your CPI? iii. What is your EAC?

Can someone show me how to do this on Excel?

Thanks

4. Using the popular Utility function U=E(r) - 0.5*A*Variance(r), what is the utility for an investor with risk-aversion index of 3, whose portfolio has an expected return of 7% and a standard deviation of 16%?

5. When consumer demand for hotel rooms increases, the average selling prices for those rooms typically increase as well. In the foodservice business that has not historically been the case. Fluctuations in consumer demand (e.g., volume differences between high demand Saturday nights and lower­volume Sunday nights) in restaurants do not typically result in menu price changes. Given that both hotels and restaurants are part of the hospitality industry, how do you account for these fundamental differences in approach toward strategic pricing? As a customer, which approach do you believe sends you the better value message? Explain your position.
