Q: Please answer correctly the following question related to the paragraph below. Which parcel of land had an excess of water that percolates downward through the soil layers? Two brothers owned two adjacent parcels of land. Tom's land was forested, while Bill's was covered with grasslands. Hint: Soil is well developed in the forest as suggested by the thick humus layers, rich diversity of large trees and animals that live there. In forests, precipitation exceeds evapotranspiration which results in an excess of water that percolates downward through the soil layers. Slow rates of decomposition leads to large amounts of fulvic acid, greatly enhancing chemical weathering. The downward percolation, in conjunction with chemical weathering leaches magnesium (Mg), iron (Fe), and aluminum (Al) from the soil and transports them downward, a process known as podzolization. This process leads to marked contrasts in the appearance and chemistry of the soil layers.
A: Tom's

Q: Please answer correctly the following question related to the paragraph below. Of the new planets, which one has more trapped terrestrial radiation? Two new planets have just been discovered in our solar system. Scientists have just landed on both and are in the process of analyzing the environment and atmosphere of each planet. What is immediately apparent is that both planets are remarkably similar to Earth since both are oxygen rich and do not require a space suit to breathe. Another similarity that one of the planets, Jarthrow, has with Earth is that it naturally outputs approximately the same amount of greenhouse gases into the atmosphere as Earth does. The other planet, Millhouse, outputs about twice as many greenhouse gases. Climate scientists are rushing to try to see if anything new can be discovered to help out our planet with these new discoveries. Hint: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature.
A: Millhouse

Q: Please answer correctly the following question related to the paragraph below. Which friend had a decreased blood flow to the heart? Fred was a good athlete in his youth, and so was Vic. Fred started eating junk food and other fatty foods in his 30's. His cholesterol is very high now. Vic became a vegan later,and he is in a very good physical shape. Hint: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death.
A: Fred

Q: Please answer correctly the following question related to the paragraph below. Which region had fewer plants with an ability to come up with a sort of strategy to decrease water use? Austria had two distinct climactic regions. The eastern region was exposed to a wet climate and had thriving vegetation, while the western region was exposed to drought. Hint: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased.
A:
eastern
