Acrosonic of the earlier example also manufactures a model G loudspeaker system in plants I and II. The output at Plant I is at most 800 systems/month whereas the output at Plant II is at most $600 / \mathrm{month}$. These loudspeaker systems are also shipped to three warehouses- $A, B$, and $C$-whose minimum monthly requirements are 500,400 , and 400 , respectively. Shipping costs from Plant I to Warehouse $A$, Warehouse $B$, and Warehouse $C$ are $\$ 16, \$ 20$, and $\$ 22$ per system, respectively, and shipping costs from Plant II to each of these warehouses are $\$ 18, \$ 16$, and $\$ 14$ per system, respectively. What shipping schedule will enable Acrosonic to meet the warehouses' requirements and at the same time keep its shipping costs to a minimum?

In the California poppy, an allele for yellow flowers $(C)$ is dominant over an allele for white flowers (c). At an independently assorting locus, an allele for entire petals $(F)$ is dominant over an allele for fringed petals (f). A plant that is homozygous for yellow and entire petals is crossed with a plant that has white and fringed petals. A resulting $F_1$ plant is then crossed with a plant that has white and fringed petals, and the following progeny are produced: 54 yellow and entire; 58 yellow and fringed; 53 white and entire; and 10 white and fringed. a. Use a chi-square test to compare the observed numbers of progeny having each phenotype with those expected for the cross. b. What conclusion can you draw from the results of the chi-square test? c. Suggest an explanation for the results.

A multicellular plant called a primrose. List three conclusions you can make about the primrose as a living thing.

The part of a plant embryo that feeds the growing seedling is the A. seed coat. B. primary root. C. endosperm. D. cotyledon.

What are two ways of reducing the negative aspects associated with using absorption costing to evaluate the performance of a plant manager?

A power plant has a power output of 1055 MW and operates with an efficiency of 0.330. Excess energy is carried away as heat from the plant to a nearby river. How much energy is transferred away from the power plant as heat? A. $0.348 \times 10^{9} \mathrm{J} / \mathrm{s}$, B. $0.520 \times 10^{9} \mathrm{J} / \mathrm{s}$, C. $0.707 \times 10^{9} \mathrm{J} / \mathrm{s}$, D. $2.14 \times 10^{9} \mathrm{J} / \mathrm{s}$.

Ford has four automobile plants. Each is capable of producing the Taurus, Lincoln, or Escort, but it can only produce one of these cars. The fixed cost of operating each plant for a year and the variable cost of producing a car of each type at each plant are given in Table 51. Ford faces the following restrictions: a. Each plant can produce only one type of car. b. The total production of each type of car must be at a single plant; that is, for example, if any Tauruses are made at plant 1, then all Tauruses must be made there. c. If plants 3 and 4 are used, then plant 1 must also be used. Each year, Ford must produce 500,000 of each type of car. Formulate an IP whose solution will tell Ford how to minimize the annual cost of producing cars. TABLE 51:

$$\begin{matrix} \text{Plant} & \text{Fixed Cost (\$)} & \text{Variable Cost (\$)}\\ \text{ } & \text{ } & \text{Taurus} & \text{Lincoln} & \text{Escort}\\ \text{1} & \text{7 billion} & \text{12,000} & \text{16,000} & \text{9,000}\\ \text{2} & \text{6 billion} & \text{15,000} & \text{18,000} & \text{11,000}\\ \text{3} & \text{4 billion} & \text{17,000} & \text{19,000} & \text{12,000}\\ \text{4} & \text{2 billion} & \text{19,000} & \text{22,000} & \text{14,000}\\ \end{matrix}$$

What does a plant need that makes it necessary for seed germination to start with the emergence of a root rather than a shoot?

PhotoTech, Inc., a manufacturer of rechargeable batteries for digital cameras, signed a contract with a digital photography company to produce three models of lithium-ion battery packs for a new line of digital cameras. The contract calls for the following:

$$\begin{array}{cc} \text { Battery Pack } & \text { Production Quantity } \\ \text { PT-100 } & 200,000 \\ \text { PT-200 } & 100,000 \\ \text { PT-300 } & 150,000 \end{array}$$

PhotoTech can manufacture the battery packs at manufacturing plants located in the Philippines and Mexico. The unit cost of the battery packs differs at the two plants because of differences in production equipment and wage rates. The unit costs for each battery pack at each manufacturing plant are as follows:

$$\begin{array}{ccc} \text { Product } & \text { Philippines } & \text { Mexico } \\ \text { PT-100 } & \$ 0.95 & \$ 0.98 \\ \text { PT-200 } & \$ 0.98 & \$ 1.06 \\ \text { PT-300 } & \$ 1.34 & \$ 1.15 \end{array}$$

The PT-100 and PT-200 battery packs are produced using similar production equipment available at both plants. However, each plant has a limited capacity for the total number of PT-100 and PT-200 battery packs produced. The combined PT-100 and PT-200 production capacities are 175,000 units at the Philippines plant and 160,000 units at the Mexico plant. The PT-300 production capacities are 75,000 units at the Philippines plant and 100,000 units at the Mexico plant. The cost of shipping from the Philippines plant is $0.18 per unit, and the cost of shipping from the Mexico plant is$0.10 per unit.

a. Develop a linear program that PhotoTech can use to determine how many units of each battery pack to produce at each plant to minimize the total production and shipping cost associated with the new contract.

The following questions are unrelated except that they all apply to plant assets and intangible assets:

1. The manager of Wired Connections Inc. regularly buys plant assets and debits the cost to Repairs and Maintenance Expense. Why would he do that, since he knows this action violates GAAP?

2. The manager of Alpine Homes debits the cost of repairs and maintenance of plant assets to Plant and Equipment. Why would she do that, since she knows she is violating GAAP?

3. It has been suggested that because many intangible assets have no value except to the company that owns them, they should be valued at $1.00 or zero on the balance sheet. Many accountants disagree with this view. Which view do you support? Why?

You have three plants—one $C_3$, one $C_4$, and one CAM plant. You also have a pH meter and a microscope. Describe how you could use only your pH meter and microscope (with the necessary supplies that go with each instrument) to identify each plant as $C_3$, $C_4$, or CAM.

All of the following cells, shown in various stages of mitosis and meiosis, come from the same rare species of plant.
a. What is the diploid number of chromosomes in this plant?
b. Give the names of each stage of mitosis or meiosis shown.
c. Give the number of chromosomes and number of DNA molecules per cell present at each stage.

Write "correct" if the vocabulary word has been used correctly, and "incorrect" if it has been used incorrectly. If the word is used incorrectly, write a sentence using the word properly.

The citizens had mixed feelings about the chemical plant. They needed the jobs the plant offered, but they could hardly stand the noxious fumes it produced.

While walking in the woods, you encounter an unfamiliar nonwoody flowering plant. If you want to know whether it is a monocot or eudicot, it would not help to look at the

a. number of seed leaves, or cotyledons, present in its seeds.

b. shape of its root system.

c. arrangement of vascular bundles in its stem.

d. size of the plant.
