3. A company manufactures two types of products: A and B. Three resources R1, R2, and R3 are required to make these products. a. Each unit of product A requires 8 units of R1 and 4 units of R2. b. Each unit of product B requires 2 units of R1, 5 units of R2, and 3 units of R3. The availabilities of resources R1, R2, and R3 are 500, 400, and 180, respectively. The manufacturer also makes a profit of $20 and $50 for products A and B, respectively. Formulate a linear programming problem whose solution will tell the manufacturer how to maximize the total profit. • What are the decision variables? • What is the objective? • What is the objective function? • What are the constraints?
2. Symbiosis, mutualism, parasitism, commensalism, myxotrophic, coencytic 1. What is a eukaryote in terms of how genetic information (DNA) is stored and cellular structures, especially those using filaments and tubules? 2. What evidence is there that mitochondria and chloroplasts have an endosymbiotic origin? 3. Look at the Eukaryote phylogeny in the text. Back in the day, you would have been taught that there were five kingdoms; Animals, (land) Plants, Fungi, Monera (Archaea and Eubacteria) and Protists – the single celled Eukaryotes. What kind of phylogenetic group would Protists be?
