Answer the following question given this paragraph: You can see how water for drinking is treated in Figure below . Treating drinking water requires at least four processes: 1. Chemicals are added to untreated water. They cause solids in the water to clump together. This is called coagulation. 2. The water is moved to tanks. The clumped solids sink to the bottom of the water. This is called sedimentation. 3. The water is passed through filters that remove smaller particles from the water. This is called filtration. 4. Chlorine is added to the water to kill bacteria and other microbes. This is called disinfection. Finally, the water is pure enough to drink. Q: When drinking water is treated, what is the term for when chemicals cause solids in the water to clump together? Choices: - clumping - oxidation - plasma - coagulation A:
coagulation
Answer the following question given this paragraph: When we consider a chemical reaction, we need to take into account both the system and the surroundings. The system includes the components involved in the chemical reaction itself. These will often take place in a flask, a beaker, a test tube, or some other container. The surroundings include everything that is not part of the system. When potassium reacts with water, part of the heat energy generated in the reaction is released into the surroundings. The boundary between system and surroundings is arbitrary, and it is generally chosen in a way that makes observations and calculations easier. Q: When we consider a chemical reaction, we need to take into account both the system and what? Choices: - date - fluctuations - time - sorroundings A:
sorroundings
Q: Answer the following question given this paragraph: Cardiologist Cardiologists are medical doctors that specialize in the diagnosis and treatment of diseases of the heart. After completing 4 years of medical school, cardiologists complete a three-year residency in internal medicine followed by an additional three or more years in cardiology. Following this 10-year period of medical training and clinical experience, they qualify for a rigorous two-day examination administered by the Board of Internal Medicine that tests their academic training and clinical abilities, including diagnostics and treatment. After successful completion of this examination, a physician becomes a board-certified cardiologist. Some board-certified cardiologists may be invited to become a Fellow of the American College of Cardiology (FACC). This professional recognition is awarded to outstanding physicians based upon merit, including outstanding credentials, achievements, and community contributions to cardiovascular medicine. Q: What is the name for medical doctors that specialize in the diagnosis and treatment of diseases of the heart? Choices: - physicists - surgeons - Doctors - cardiologists A:
A: cardiologists
Question: Answer the following question given this paragraph: Q: What type of logic can lead to important conclusions from the collecting and analyzing of observations? Choices: - gravitational reasoning - primitive reasoning - conductive reasoning - inductive reasoning A:
Answer: inductive reasoning

Answer the following question given this paragraph: Efforts to reduce future global warming mainly involve energy use. We need to use less energy, for example, by driving more fuel-efficient cars. We also need to switch to energy sources that produce less carbon dioxide, such as solar and wind energy. At the same time, we can increase the amount of carbon dioxide that is removed from air. We can stop destroying forests and plant new ones. Q: Reducing the production of what gas, or removing it from the air, are practices that could reduce global warming? Choices: - helium - hydrogen - oxygen - carbon dioxide A:
**Answer**
carbon dioxide

Answer the following question given this paragraph: An example of a mutualistic relationship is between herbivores (plant-eaters) and the bacteria that live in their intestines. The bacteria get a place to live. Meanwhile, the bacteria help the herbivore digest food. Both species benefit, so this is a mutualistic relationship. The clownfish and the sea anemones also have a mutualistic relationship. The clownfish protects the anemone from anemone-eating fish, and the stinging tentacles of the anemone protect the clownfish from predators ( Figure below ). Another example of this type of symbiotic relationship is the relationship between the plover bird and the African crocodile. The tiny blackbird acts as a toothpick for the fierce crocodile, and helps by removing tiny morsels of food that are stuck between the crocodile's teeth. These food remains are the source of food for the bird. Another example is between the ostrich and the zebra. The ostrich always moves with the herd of zebras since it has a poor sense of hearing and smell, whereas the zebra has very sharp senses. The ostrich has a keen sense of sight, which the zebra lacks. Hence, these two species depend on each other to warn one another of any nearby imposing dangers. Q: Herbivores and the bacteria that live in their intestines demonstrate a two-way beneficial relationship called what? Choices: - parasitism - pragmatism - syncretism - mutualism A:
**Answer**
mutualism
