[Q]: I read this background article the other day: During sexual reproduction, mating with a close relative (inbreeding) often leads to inbreeding depression. Inbreeding depression is considered to be largely due to expression of deleterious recessive mutations. The effects of inbreeding have been studied in many vertebrate species. I am facing a new situation today: Keith is a zoologist. He studies large predators. Last year, he was studying different species of lions. First, he visited the Gir forest in India. There he found the Asiatic Lions. Unfortunately, only few Asiatic Lions are left in the wild, and they have to mate with their close relatives. He then visited the Serengeti reserve in Tanzania. There he found that the African Lions were not forced to mate with close relatives due to their large number. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which species of lion would have more deleterious recessive mutations, Asiatic or African?
****
[A]: Asiatic
input: Please answer the following: I read this background article the other day: Another example of negative feedback has to do with blood glucose levels. When glucose (sugar) levels in the blood are too high, the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen, which is stored in the liver. As blood glucose levels decrease, less insulin is produced. When glucose levels are too low, another hormone called glucagon is produced, which causes the liver to convert glycogen back to glucose. I am facing a new situation today: Tim and Fred were two students. Tim studied about negative feedback and the pancreas, while Fred studied about the stomach and the jejunum. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student read less about the pancreas secreting insulin to stimulate the conversion of glucose into glycogen?
++++++++++
output: Fred
Please answer this: I read this background article the other day: During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years. A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska. From an anthropological point of view, researchers study the native Inuit peoples of Alaska as they have become extremely accustomed to adapting to ecological and climate variability.[1] I am facing a new situation today: Two countries situated at different latitudes are exposed to climate change. Iceland is located closer to the North Pole, while Ecuador is located near the Equator. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country will feel the effects of climate change less quickly?
++++++++
Answer: Ecuador
Problem: I read this background article the other day: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! I am facing a new situation today: Two groups of children studied about some of the planets from our Solar system and their atmospheres. Group E studied about Earth, while group V studied about the planet Venus. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group studied less about temperatures at the surface of Venus?

A: Group E
Problem: Given the question: I read this background article the other day: Evidence from seismology, heat flow at the surface, and mineral physics is combined with the Earth's mass and moment of inertia to infer models of the Earth's interior its composition, density, temperature, pressure. For example, the Earth's mean specific gravity (5.515) is far higher than the typical specific gravity of rocks at the surface (2.73.3), implying that the deeper material is denser. This is also implied by its low moment of inertia ( 0.33 M R2, compared to 0.4 M R2 for a sphere of constant density). However, some of the density increase is compression under the enormous pressures inside the Earth. The effect of pressure can be calculated using the AdamsWilliamson equation. The conclusion is that pressure alone cannot account for the increase in density. Instead, we know that the Earth's core is composed of an alloy of iron and other minerals.Reconstructions of seismic waves in the deep interior of the Earth show that there are no S-waves in the outer core. This indicates that the outer core is liquid, because liquids cannot support shear. The outer core is liquid, and the motion of this highly conductive fluid generates the Earth's field. Earth's inner core, however, is solid because of the enormous pressure.Reconstruction of seismic reflections in the deep interior indicate some major discontinuities in seismic velocities that demarcate the major zones of the Earth: inner core, outer core, mantle, lithosphere and crust. The mantle itself is divided into the upper mantle, transition zone, lower mantle and D layer. Between the crust and the mantle is the Mohorovicic discontinuity.The seismic model of the Earth does not by itself determine the composition of the layers. For a complete model of the Earth, mineral physics is needed to interpret seismic velocities in terms of composition. The mineral properties are temperature-dependent, so the geotherm must also be determined. This requires physical theory for thermal conduction and convection and the heat contribution of radioactive elements.... I am facing a new situation today: John is a geologist. He was trying to figure out how the Earth's inner core is made. To that end, he compared earth's physical characteristics to available items. First he took a sample of surface rock, which he labeled as item B. Then he took a sphere of constant density, which he labeled as item C. Finally, he labeled the Earth as item A. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which would have higher moment of intertia, item A or item C?
++++++++++++++++++++++++++++++++
The answer is:
item C
Problem: I read this background article the other day: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. I am facing a new situation today: John is a an ophthalmologist in a local hospital. Today, he has seen two patients, patient A and patient B. Patient A had hyperopia, but patient B didn't have any issues with eyes. John would now treat the patient that have eye problem. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would patient B see nearby objects clearer or blurrier than patient A?

A:
clearer
