Please answer this: I have a new situation: Two neighbors Paul and Dean studied toghether often. this week they got together and Paul started studying about the Gaia hypothesis, while Dean studied Einstein's Theory of Relativity. But I can use this background: 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. What is an answer for this question: Which person studied more about homeostasis?

Answer: Paul

Please answer this: I have a new situation: This year scientist found concrete evidence of existence of black holes by taking photograph of one. Unfortunately, the originator of black hole theory, Stephen Hawking, was never awarded a Nobel prize despite letting science advance in big leap because his theory could not be verified during his lifetime. On the other hand, scientist B has received Nobel prize because he has based his theory on the earlier theory of scientist A. But I can use this background: The above example shows how science generally advances. New evidence is usually used to improve earlier ideas rather than entirely replace them. In this way, scientists gradually refine their ideas and increase our understanding of the world. On the other hand, sometimes science advances in big leaps. This has happened when a scientist came up with a completely new way of looking at things. For example, Albert Einstein came up with a new view of gravity. He said it was really just a dent in the fabric of space and time. What is an answer for this question: Would scientist B increased our understanding of the world more or less than scientist A?

Please answer this: I have a new situation: Two farms were situated on opposite banks of a large river flowing into the ocean. Hill farm practiced conventional agriculture, while Dew farm practiced permaculture design within the context of organic farming. But I can use this background: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. What is an answer for this question: Which farm generated fewer marine dead zones because of fertilizer and chemical use?
