Answer the following question given this paragraph: Giant steps in science may occur if a scientist introduces a major new idea. For example, in 1666, Isaac Newton introduced the idea that gravity is universal. People had long known that things fall to the ground because they are attracted by Earth. But Newton proposed that everything in the universe exerts a force of attraction on everything else. This idea is known as Newton's law of universal gravitation. Q: Who proposed that everything in the universe exerts a force of attraction on everything else? Choices: - bell - einstein - wilson - newton A:
newton
Answer the following question given this paragraph: Blood flows through the heart in two separate loops, which are indicated by the arrows in Figure above. You can think of them as a "left side loop" and a "right side loop. " The right side of the heart collects oxygen-poor blood from the body and pumps the blood to the lungs. In the lungs, carbon dioxide is released and oxygen obtained by the blood. The left side of the heart carries the oxygen-rich blood back from the lungs and pumps it to the rest of the body. The blood delivers oxygen to the body's cells, returning the oxygen-poor blood back to the heart. Q: What type of blood does the right side of the heart collect and then pump to the lungs? Choices: - nitrogen-rich blood - oxygen-rich blood - nitrogen-poor blood - oxygen-poor blood A:
oxygen-poor blood
Q: Answer the following question given this paragraph: Just about all human behaviors are learned. Learned behavior is behavior that occurs only after experience or practice. Learned behavior has an advantage over innate behavior : it is more flexible. Learned behavior can be changed if conditions change. For example, you probably know the route from your house to your school. Assume that you moved to a new house in a different place, so you had to take a different route to school. What if following the old route was an innate behavior? You would not be able to adapt. Fortunately, it is a learned behavior. You can learn the new route just as you learned the old one. Q: What type of behavior is most flexible? Choices: - innate behavior - reflex behavior - adaptation - learned behavior A:
A: learned behavior
Question: Answer the following question given this paragraph: The corona is the halo around the Sun. Q: The corona surrounds which major object in our solar system? Choices: - Neptune - Earth's moon - Jupiter - the sun A:

Answer the following question given this paragraph: Heat involves the transfer of thermal energy between two bodies that are at different temperatures. If you held a flask containing a reaction that releases energy, you would be able to feel the heat being transferred from the reaction into your hand. A process in which heat is released is referred to as exothermic . Conversely, reactions that absorb energy will remove energy from the surroundings, causing the container to feel cold. For example, dissolving ammonium nitrate in water will significantly lower the water temperature. Processes that absorb energy from their surroundings are called endothermic . Q: The process when heat is released is referred to as what? Choices: - geothermal - endothermic - insular - exothermic A:
**Answer**
exothermic
