A central question in biology is, how do we have > 200 different cell types, complete with unique cell morphologies and functions, when all cells have the same DNA (the concept of genomic equivalence). Epigenetic regulation of gene transcription is one way to explain this. Define what is meant by epigenetic regulation of gene transcription, including different general epigenetic mechanisms, and describe three different contexts of a developmental process that is associated with epigenetic changes that we have discussed in class.

1. Find one new fossil discovery, how it did/did not change what is already known for species related to the discovery and how it relates to Darwin’s theory of evolution

2. DNA evidence of changes to the evolutionary tree that is currently accepted

3. Find one new human DNA or fossil or anthropological discovery and explain how it relates to Darwin’s theory of evolution

4. Choose a new method of artificial selection for crops or animals (pets or livestock usually) and explain its connection with Darwin’s theory of evolution.

World oil prices have been rapidly swinging over the last few years, in part because of the declining value of the U.S. dollar, changes in supply and demand, and OPEC’s attempts to manage output in order to maintain higher prices. (OPEC stands for the Organization of Petroleum Exporting Countries) As the president of an oil producing and exporting company in Alberta: Explain how you may use hedging to protect your company’s income. Share a recent publication with your fellow students and your instructor.

Suppose the island of Atlantis imports only one product, machinery parts, at a per unit price of $125. At the same time, its only export good is palm oil, which sells at $250 per unit on world markets. Atlantis currently exports 100 units of palm oil.
Suppose that over time the import price of machinery parts rises to $150 while the world palm oil price decreases to $200.

Are these price changes in line with the Prebisch-Singer hypothesis? Why or why not

1. The Federal Reserve believes that a certain rate of interest on Federal Funds is associated with price stability (which is 2% rate of inflation). However, the Federal Funds rate tends to fluctuate with the changes in the demand for federal funds by the banking system. Hence, to maintain the Federal Funds rate at the desired rate or to raise it or lower it to a new rate the Federal Reserve System undertake open market operations, or few other measures.

1. What is the difference between dynamic open market operations and defensive open market operations?

Define perimenopause, surgical menopause, stress menopause, and postmenopause. What are the signs of menopause? What other life changes may influence a women's experience during menopause? Describe women at the highest risk for osteoporosis. Describe the traditional and alternative therapies for the conditions associated with menopause. Design a health, nutrition, and exercise program for middle-aged and older adults

Consider a firm with an EBIT of $10,900,000. The firm finances its assets with $50,800,000 debt (costing 6.9 percent) and 10,400,000 shares of stock selling at $10.00 per share. The firm is considering increasing its debt by $25,400,000, using the proceeds to buy back shares of stock. The firm is in the 40 percent tax bracket. The change in capital structure will have no effect on the operations of the firm. Thus, EBIT will remain at $10,900,000.

Calculate the EPS before and after the change in capital structure and indicate changes in EPS.

Braskem S.A., a large Brazilian petrochemical company, reported a balance R$1,594.9 million in Accounts Receivable at the beginning of 2013 and R$1,497.0 million at the end of 2013. Its income statement reported total sales revenue of R$12,134.5 million at the end of 2013. Braskem applies IFRS and reports its results in thousands of reals (R$), the Brazilian currency. Assuming that Braskem makes all sales on account, present journal entries that account for all changes in accounts receivable during 2013

In words, but making use of equations where appropriate, explain how the Principal of Conservation of Linear Momentum is a demonstration of Newton’s third law of motion. In particular, consider a simple collision between two objects. The collision may be either elastic or inelastic. It may be head-on or oblique. State how the changes in motion as a result of this collision relate to Newton’s Third Law. Finally expand your reasoning to cover a many particle system.

Suppose that people realize that they must save a larger proportion of their income in order to retire, and they simultaneously begin to use new technology that allows them to reduce their holdings of real cash balances as a proportion of their income. Giving reasons, clearly explain the combined impact of these two changes in household behaviour on equilibrium output and interest rates in a closed economy using the IS–LM analysis. You may need to draw a diagram to determine the impact. However, do not provide a diagram with the answer. (125 words maximum)
