Regarding fermentation: This process allows energy production to continue in low O2 conditions. Pyruvate acts as the final electron acceptor, regenerating NAD+. In humans, fermentations results in the production of lactate (lactic acid). Fermentation in animals can provide quick burst of energy over a short period of time. All of these choices are correct.

(28 Points) The following are production possibilities tables for Mexico and the United States. Also, for simplicity, suppose that the labor resources in the United States and Mexico are of equal size. Assume that before specialization and trade, the production and consumption for Mexico is alternative C and for the United States is alternative T. Table 1: Mexico's Production Possibilities Table (in Tons) Production Alternative A B C D Apples 0 20 24 40 Strawberries 15 10 9 5 Table 2: U.S. Production Possibilities Table (in Tons) Production Alternative R S T U Apples 0 30 33 60 Strawberries 30 20 19 10 A. (2 Points) Draw the production possibility frontiers (PPF) for each country in the absence of trade. B. (2 Points) Which country has an absolute advantage in the production of apples? strawberries? C. (4 Points) What is the opportunity cost of the two products within the two countries? D. (2 Points) Which country has a comparative advantage in the production of apples? strawberries? E. (4 Points) Are opportunity costs such that the two areas should specialize? If so, what product should each produce? F. (2 Points) What is the total gain in apples' and strawberries' output that would result from such specialization? G. (2 Points) What are the limits of the terms of trade? H. (4 Points) Suppose actual terms of trade are 1 ton of apples for 3.5 tons of strawberries and 35 tons of apples are exchanged for 10 tons of strawberries. Use this information to draw a trading possibility curve along with the PPFs for each country. I. (4 Points) What are the gains from specialization and trade for each country? J. (2 Points) Explain why this illustration allows you to conclude that specialization according to comparative advantage results in more efficient use of world resources.
