Problem: Please answer correctly the following question related to the paragraph below. Which team didn't learn that if all of the wolves are removed from a population, then the population of deer or rabbits may increase? Two teams studied two types of animals: team A studied predators, while team B studied grazers. They learned a lot from this experience. Hint: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species.

A: team B
Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which island had fewer people dying? Two Islands were discovered by settlers, A small group of people moved to South island, but most of them moved to North island. People on North island had frequent food shortages. Hint: In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease.

input question: Please answer correctly the following question related to the paragraph below. Will the potential energy increase or decrease as the positive and negative poles of a magnet get closer to each other? Adam is playing with some magnets which have a positive and negative pole. He tries to push them together but cant seem to do it. when he flips one of the magnets around that actually snap together very quickly. Hint: It is often easy to think of the change in energy as a mountain or an inverted cone, depending on the situation. Imagine a positive point charge, with the corresponding electric field around it. If you are moving another positive point charge, the situation is like a mountain, with the original point charge at the peak. As the second charge moves towards the first, it must go up the mountain. This requires work, and increases the potential energy of the system. If, however, the second charge is a negative point charge, the two charges attract each other and the situation is like a cone the second charge easily falls towards the first, decreasing the potential energy. It would then require work to get the second charge up and out of the cone, away from the first charge.???
output answer: decrease
Please answer correctly the following question related to the paragraph below. Which landmass had its atmosphere destroyed by bromine gasses? The researches studied the atmosphere in Antarctica, and close to Greenland. They found out there's an ozone hole over Antarctica. Hint: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk.

Answer: Antarctica
Q: Please answer correctly the following question related to the paragraph below. Given The Gaia hypothesis, would this dome be considered a living organism or non-living? A scientist with an interesting idea for an experiment begins building a dome. This dome will be completely cut off from the rest of the world. It will produce all of its own resources, breathable air, anything needed to sustain life, putting it into a state of homeostasis. Hint: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention.
A: living
[Q]: Please answer correctly the following question related to the paragraph below. Which group had fewer people with plaques? Two groups of patients were under observation for heart disease. The Red group was composed of people with low cholesterol, while the Yellow group was comprised of people with very high cholesterol. 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.
