Problem: Given the question: I can use this background: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Now, I have a new situation: Two friends studied permaculture together. Bill studied about mycorrhiza, while Red studied about hugel kultur. Answer this question please: Which friend learned more about fungus colonizing the roots of a host plant by growing around the root cells?

The answer is:
Bill

Problem: Given the question: I can use this background: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3) and phosphates (PO4) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally). Now, I have a new situation: Two dairy farms were supplying milk and other milk products to the surrounding counties. Sunny farm practiced organic farming and produced organic milk, while Cloud farm was into conventional milk production. Answer this question please: Which farm leached fewer phosphates into the water?

The answer is:
Sunny

Problem: Given the question: I can use this background: The Figure below shows a graph of plotted against pressure for 1 mol of a gas at three different temperatures - 200 K, 500 K, and 1000 K. An ideal gas would have a value of 1 for that ratio at all temperatures and pressures and the graph would simply be a horizontal line. As can be seen, deviations from an ideal gas occur. As the pressure begins to rise, the attractive forces cause the volume of the gas to be less than expected and the value of drops under 1. Continued pressure increase results in the volume of the particles to become significant and the value of rises to greater than 1. Notice, that the magnitude of the deviations from ideality is greatest for the gas at 200 K and least for the gas at 1000 K. Now, I have a new situation: Marcus is working with a sealed container of oxygen. He is trying see how temperature effects its deviations from ideality. He slowly increases the temperature of the oxygen and continues to measures its deviations. Answer this question please: Will increasing the temperature cause the magnitude of deviations to increase or decrease?

The answer is:
decrease
