input: Please answer the following: Two brothers went to the doctor's office for an appointment. The doctor discovered that Tim had very high levels of cholesterol, while Jim had normal levels. Given the paragraph above, please answer correctly the following question: Which brother experiences a decrease in blood flow? 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.

input: Please answer the following: Scientists studied two island. One with an old ecosystem named Old island, and the other with a newly formed and forming ecosystem named New island. Both islands were inhabited, Old island being heavily inhabited. Given the paragraph above, please answer correctly the following question: Which island had a more favorable amount of rainfall for new ecosystems? Hint: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues.

input: Please answer the following: Alexiev and Sabrina were enthusiastic chemistry students completing the first experiment of their new course. They both started the experiment with pure water, and had to perform different experimental protocols to make changes to the water. At the end of the experiment, both of them measured the concentration of hydronium ions present in their reaction mixtures. Alexiev had a high concentration of hydronium ions present, while Sabrina had a low concentration present in her mixture. Given the paragraph above, please answer correctly the following question: Which person's mixture, Alexiev's or Sabrina's, has a lower pH value at the end? Hint: If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid . As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is. Did you ever taste vinegar? Like other acids, it tastes sour. Stronger acids can be harmful to organisms. For example, stomach acid would eat through the stomach if it were not lined with a layer of mucus. Strong acids can also damage materials, even hard materials such as glass.

input: Please answer the following: Jim and Greg are brothers who both run their own farms, but they rarely see each other due to them living in different states. Greg runs a farm in Texas where he rarely sees rain so he spends much of his day watering his crops. Jim lives in Illinois where it rains much more regularly so he has more time to spend dealing with his farm animals instead of watering his plants. Both men intentionally purchased their farms next to lakes since they have always loved fishing during their free time. The brothers are currently planning a fishing trip together, but they are just debating which lake to travel to. Given the paragraph above, please answer correctly the following question: Does Greg's lake have more or less oxygen than Jim's? 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.
