PureCoffee

PureCoffee imports high quality coffee beans from Africa and South America. They roast the beans in a innovative process slowly and gently to create a unique taste of coffee. Pure Coffee serves three markets (M1, M2, and M3) in Europe. Market demand for the next week is given in the following table.

To serve Europe they have two roasting plants available - one in the North of Europe (N) and one in the South of Europe (S).

Currently they are using two distribution centers in Europe to connect the roasting plants with markets. They ship the roasted beans from the production sites to the distribution centers and distribute from there to three different markets.
The cost to transport a ton of roasted beans from a roasting plant to a dibstrution center and from the distribution center to the customers depends on the distances between the different locations. These costs are given in the two tables below:

1. PureCoffee wants to minimize the total weekly cost. They ask you to optimize the roasted beans flow from the processing facilities to their customers.

In the optimal solution, what is the minimum total weekly cost of moving roasted beans from roasting plants to customers? Enter your answer in Euros without a currency symbol.

2. How many tons of roasted beans should PureCoffee ship through Distribution Center B per week?

1. What is the difference between the eyes of most animals you are familiar with and the eyespots of Dugesia?

-----

2. How does the head of Dugesia move differently from the tail?

3. Where is the feeding tube located? Why is this unusual for bilaterally symmetrical organisms?

4. Is the gastrovascular cavity of Dugesia a simple sac? How is it divided and what advantage do these divisions offer?
5. Consider objective 1 listed at the beginning of this exercise. How could being monoecious contribute to evolutionary success of flatworms in their environment?
6. Planarians have a head. In biological terms, what constitutes a “head”? How does it relate to objectives 1, 4, and 7?
7. Planaria lack specialized gas-exchange organs. How do you think planaria accomplish this task?

5. Limb development. Different species display characteristic digit patterning along the anterior-posterior axis. The forelimbs of bats are modified such that the posterior digits are elongated and maintain their webbing (to make the functional bat wing). Researchers observed that in addition to the normally timed expression of Sonic hedgehog (Shh) in the bat ZPA, there is a second phase of both Fgf8 and Shh expression in the developing forelimb in the interdigital tissue. Using what you know about the functions of Fgf8 and Shh in limb outgrowth in the chick that we talked about in class, how does the second phase of Fgf8 and Shh contribute to both the elongation of the forelimb digits and to the maintenance of the webbing between the digits?
