Answer the following question given this paragraph: Digestive System Organs The easiest way to understand the digestive system is to divide its organs into two main categories. The first group is the organs that make up the alimentary canal. Accessory digestive organs comprise the second group and are critical for orchestrating the breakdown of food and the assimilation of its nutrients into the body. Accessory digestive organs, despite their name, are critical to the function of the digestive system. Q: What are accessory digestive organs critical for breaking down? Choices: - pathogens - enzymes - hormones - food A:
food
Answer the following question given this paragraph: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing. Q: For what kind of animal is communication essential? Choices: - anti-social animals - new born animals - migrating animals - social animals A:
social animals
Q: Answer the following question given this paragraph: Waves topple over and break on the shore because of friction with the bottom in shallow water. Q: What force causes waves to topple over and break on the shore? Choices: - momentum - tension - vibration - friction A:
A: friction
Question: Answer the following question given this paragraph: The remaining 5% are scattered around other plate boundaries. A few earthquakes take place away from plate boundaries. These are intraplate earthquakes. Q: A few earthquakes take place away from plate boundaries, these are called what? Choices: - outer earthquakes - deformation earthquakes - distant earthquakes - intraplate earthquakes A:
Answer: intraplate earthquakes

Answer the following question given this paragraph: Lymph that collects in tissues slowly passes into tiny lymph vessels. Lymph then travels from smaller to larger lymph vessels. Muscles around the lymph vessels contract and squeeze the lymph through the vessels. The lymph vessels also contract to help move the lymph along. Eventually, lymph reaches the main lymph vessels, which are located in the chest. From these vessels, lymph drains into two large veins of the cardiovascular system. This is how lymph returns to the blood. Q: Which part of the wave helps make the wave bend and cause refraction? Choices: - dense part - heavy part - bright part - shallow part A:
**Answer**
shallow part
Answer the following question given this paragraph: with only certain radii were allowed. Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius. The orbit closest to the nucleus represented theground state of the atom and was most stable; orbits farther away were higher-energy excited states. Transitions from an excited state to a lower-energy state resulted in the emission of light with only a limited number of wavelengths. Bohr's model could not, however, explain the spectra of atoms heavier than hydrogen. Most light is polychromatic and contains light of many wavelengths. Light that has only a single wavelength is monochromatic and is produced by devices called lasers, which use transitions between two atomic energy levels to produce light in a very narrow range of wavelengths. Atoms can also absorb light of certain energies, resulting in a transition from the ground state or a lower-energy excited state to a higher-energy excited state. This produces an absorption spectrum, which has dark lines in the same position as the bright lines in the emission spectrum of an element. Q: What is light that has only a single wavelength called? Choices: - primary - fluorescent - spectroscopy - monochromatic A:
monochromatic
