irections: Answers must be in essay form. Outline form is not acceptable. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely before you begin. An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, Seedings were germinated on moist paper towels at 20°C for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. CUMULATIVE OXYGEN CONSUMPTION O Variety A 7"C - Variety A 17e O Variety B 7°C • Variety B 17°C 20 40 Time (min) 60 8. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD*. Predict he most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction. v + , N - C (qu) Oxygen Consumption

Figure 47.6 Scientists measured the relative abundance ot fern spores above and below the K-Pg boundary in this reck sample. Which of the following statements most likely represents their findings? An abundance of fern spores from several species was found below the K-Pg boundary, but none was found above. An abundance of fern spores from several species was found above the K-Pg boundary, but none was found below. An abundance of fern spores was found both above and below the K-Pg boundary, but only one species was found below the boundary , and many species were found above the boundary. Many species of fern spores were found both above and below the boundary, but the total number of spores was greater below the boundary.

Intraspecific competition is a competition between members of the same species and is commonly observed in crop plants. Table 6.2 shows the results of a greenhouse experiment which examined the effects of density on the germination and growth of barley. Plants were grown for two weeks in 10- cm diameter pots kept in identical environmental conditions and watered regularly. At the end of the experiment the plants were cropped by cutting the stems at the soil surface. Based from the given table and graph, discuss the data and the relationship of the two factors (Mean wet biomass of plants (g) and Number of plants that germinated). Then, what is the effect of density to the Mean wet biomass of plants?
