About 3 million years ago, the Isthmus of Panama (a narrow strip of land connecting North and South America) formed, dividing marine organisms into Pacific and Caribbean populations. Researchers have examined species of snapping shrimp on both sides of the isthmus. Based on the morphological species concept, there appeared to be seven pairs of closely related species, with one species of each pair in the Pacific and the other in the Caribbean. The different species pairs live at different depths in the ocean. Using mitochondrial DNA sequences, the researchers estimated phylogenies and found that each of these species pairs (sister species), separated by the isthmus, were indeed each other's closest relatives. The researchers investigated mating in the lab and found that many species pairs were not very interested in courting with each other, and, any that did mate, almost never produced fertile offspring.

1. These species are distinctive species under all three species concepts.

a. Likely

b. Not Likely

2. Sympatric speciation caused the difference between the seven species on the Pacific side.

a. Likely

b. Not Likely

3. Sympatric speciation caused the differences between the sets of sister species on either side of the Isthmus.

a. Likely

b. Not likely

4. If sea levels rises enough to cover the isthmus, the sister species on either side of the isthmus will likely undergo fusion.

a. Likely

b. Not likely

5. Habitat isolation is the only reproductive isolating barrier preventing the formation of hybrid from the different sister species.

a. Likely

b. Not likely

6. If sea levels rise enough to cover the isthmus, the frequency of hybrid offspring would decrease.

a. Likely

b. Not likely

7. What other type of reproductive isolating barrier is creating the reinforcement of differences between the sister (closely related) shrimp species pairs?

a. Behavioral isolation

b. Gametic isolation

c. Temporal isolation

d. Reduced hybrid fertility

e. Both A and D

Your company is looking at updating its production process by adding a new piece of equipment. The company uses a 9% cost of capital in its capital budgeting decisions. The new equipment will cost $350,000 and the company expects the following annual cash flows for 5 years as a result of the purchase (note that year 1 is negative): Year 1 (10,000) Year 2 45,000 Year 3 127,000 Year 4 168,000 Year 5 145,000 A) Calculate the Net Present Value (NPV) of the acquisition project. B) Calculate the Internal Rate of Return (IRR) of the acquisition project. C) Should the company purchase the new equipment? Explain.

"Costs and Profit Maximization Under Competition", tells us that in deciding what quantity to produce, a firm should look at all its costs. We are reminded the "Total Cost" includes Opportunity Costs, not just money costs. Discuss the major costs that a business faces, being sure to distinguish between "Explicit Costs", and "Implicit Costs", using an example from a real or fictitious operating business.
