Answer the following question given this paragraph: There are many blood vessels in the kidneys ( Figure above ). The kidneys remove urea and other wastes from the blood through tiny filtering units called nephrons. Nephrons ( Figure below ) are tiny, tube-shaped structures found inside each kidney. Each kidney has up to a million nephrons. Each nephron collects a small amount of fluid and waste from a small group of capillaries. Q: What are the tiny, tube-shaped structures found inside a kidney called? A:
OPTIONS:
- neurons
- jejunum
- dendrites
- nephrons

Answer: nephrons

Question: Answer the following question given this paragraph: A: Electric charges flow when they have electric potential energy. Potential energy is stored energy that an object has due to its position or shape. Q: What is the term for stored energy that an object has due to its position or shape? A:
OPTIONS:
- kinetic energy
- mechanical energy
- vertical energy
- potential energy
Answer: potential energy

input with options: Answer the following question given this paragraph: Both of these people are participating in a board sport, but the man on the left is snowboarding in Norway while the woman on the right is sandboarding in Dubai. Snow and sand are both kinds of matter, but they have different properties. What are some ways snow and sand differ? One difference is the temperature at which they melt. Snow melts at 0C, whereas sand melts at about 1600C! The temperature at which something melts is its melting point. Melting point is just one of many physical properties of matter. Q: The temperature at which something melts is refered to as what? A:
OPTIONS:
- precipitation point
- evaporation point
- boiling point
- melting point
output: melting point

- polar and arctic
- marine and tropical
- polar and tropical Now, answer this question: Answer the following question given this paragraph: Most air masses form over polar or tropical regions. They may form over continents or oceans. Air masses are moist if they form over oceans. They are dry if they form over continents. Air masses that form over oceans are called maritime air masses. Those that form over continents are called continental air masses. Figure below shows air masses that form over or near North America. Q: Most air masses form over what two types of regions? A:
A:
output: polar and tropical

Question: Answer the following question given this paragraph: Bases are ionic compounds that produce negative hydroxide ions (OH - ) when dissolved in water. An ionic compound contains positive metal ions and negative nonmetal ions held together by ionic bonds. (Ions are atoms that have become charged particles because they have either lost or gained electrons. ) An example of a base is sodium hydroxide (NaOH). When it dissolves in water, it produces negative hydroxide ions and positive sodium ions (Na + ). This can be represented by the equation:. Q: What are the ionic compounds that produce negative hydroxide ions when dissolved in water? A:
OPTIONS:
- isotopes
- acids
- enzymes
- bases
Answer:
bases
