[Q]: Park farm and Fiddle farm provided Red city with tonnes of produce annually. Fiddle farm used and abundance of fertilizers and pesticides, while Park farm didn't use any of those substances. Given the paragraph above, please answer correctly the following question: Which farm caused less fertilizer to end up in ponds? Hint: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf.

input: Please answer the following: Two colleagues read about types of chemical reactions. Sean studied about the influence of temperature on chemical reactions. Gabe studied about other influencing factors. Given the paragraph above, please answer correctly the following question: Which student read more about the activation energy barrier? Hint: Raising the temperature of a chemical reaction usually results in a higher rate of reaction. When the reactant particles are heated, they move faster and faster. This results in a greater frequency of collisions. A more important effect of the temperature increase is that the collisions occur with a greater force and are thus more likely to surmount the activation energy barrier and go on to form products. Increasing the temperature of a reaction increases the number of effective collisions between reacting particles, so the reaction rate increases.

Please answer this: Moon and Earth were two sister planets, both inhabited by humans. People of Earth released large quantities of greenhouse gases into the atmosphere over the last decades, while Moon people were taking good care of their planet and the environment. Given the paragraph above, please answer correctly the following question: Which planet didn't experience the heating effect of greenhouse gases? Hint: Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future).

Answer: Moon
Problem: San Francisco and Baltimore both have large manufacturing and production industries and both border large oceans. San Francisco has been burning large amounts of fossil fuels recently to fuel their increased manufacturing and production of automobiles. Baltimore, however, has shifted to renewable resources recently, and as a result they have drastically decreased the amount of fossil fuels that are used to produce and manufacture steel. Given the paragraph above, please answer correctly the following question: Which city, San Francisco or Baltimore, releases more carbon dioxide into the atmosphere? Hint: Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume.

A: San Francisco
Problem: Given the question: Two boys read about the Earth, Evolutionism and the Gaia hypothesis. Brad liked Evolutionism more, while Stan preferred the Gaia theory, and agreed with it. Given the paragraph above, please answer correctly the following question: Which boy agreed that the Earth tends to achieve 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.

Problem: Dorothy is riding an elevator. The elevator has bristles running up the side of the tracks so her jeans are rubbing against them. When he gets to the top of the elevator she accidentally brushes a piece of metal and gets a small electric shock from it. Given the paragraph above, please answer correctly the following question: Will objects moving from one object to anothr cause the first to become positively charged or negatively charged? Hint: Electrons can be removed from some objects using friction, simply by rubbing one substance against another substance. There are many examples of objects becoming charged by friction, including a rubber comb through hair, and a balloon on a sweater. In both these instances, the electrons move from the second object to the first, causing the first object to become negatively charged and the second one positively charged. Friction between the tires on a moving car and the road cause the tires to become charged, and wind causes friction between clouds and air which causes clouds to become charged and can result in tremendous bolts of lightning.

A:
positively
