Question: Two rivers, The Minninnippi and The Cedar, flow into the same ocean. The Minninnippi is surrounded almost entirely by farm lands due its location in a flat area of the country that sees regular rainfall. The majority of these farms will have runoff from their crop soil flow into the river. The Cedar is located mostly inside an unpopulated forest. Currently, not much industrialization or settling by humans has happened near The Cedar. Is it more or less likely that the ocean water near The Minninnippi will experience hypoxia? Hint: 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.

Question: Two sister cities were part of an air pollution study. While Prague had big air pollution problems, Belfast was eco-friendly and its inhabitants were healthy. Which city had fewer people with an increased chance of dying from other diseases? Hint: Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That's because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment.
Answer: Belfast

Question: Ben and Andy studied minerals and micro-nutrients. Ben studied more about magnesium, zinc and molybdenum, while his buddy Andy studied about sodium and potassium. Which person studied more about Energy in ATP ? Hint: Sodium and potassium are two of the most important elements in living things. They are present mainly as positively charged ions dissolved in water. The sodium-potassium pump moves sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. In both cases, the ions are moving from an area of lower to higher concentration. Energy in ATP is needed for this "uphill" process. Figure below shows how this pump works. Trace these steps from left to right in the figure

Andy
