Answer the following question given this paragraph: Asthma is a chronic illness in which the bronchioles, the tiny branches into which the bronchi are divided, become inflamed and narrow ( Figure below ). The muscles around the bronchioles contract, which narrows the airways. Large amounts of mucus are also made by the cells in the lungs. People with asthma have difficulty breathing. Their chests feel tight, and they wheeze. Asthma can be caused by different things, such as allergies. Asthma can also be caused by cold air, warm air, moist air, exercise, or stress. The most common asthma triggers are illnesses, like the common cold. Asthma is not contagious and cannot be passed on to other people. Children and adolescents who have asthma can still lead active lives if they control their asthma. Asthma can be controlled by taking medication and by avoiding contact with environmental triggers for asthma, like smoking. Q: Asthma affects what tiny branches into which the bronchi are divided? Choices: - macrophages - cilia - platelets - bronchioles A:
bronchioles
Answer the following question given this paragraph: Q: What part of a plant, which is attached to its stem nodes, is the "main organ" of photosynthesis? Choices: - flowers - roots - spores - leaves A:
leaves
Q: Answer the following question given this paragraph: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis ( Figure below ) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. Q: Cellular respiration and photosynthesis are important parts of which cycle? Choices: - vapor cycle - greenhouse effect - water cycle - carbon cycle A:
A: carbon cycle
Question: Answer the following question given this paragraph: Did you ever see a dog sit on command? Have you ever watched a cat trying to catch a mouse? These are just two examples of the many behaviors of animals. Animal behavior includes all the ways that animals interact with each other and the environment. Examples of common animal behaviors are pictured in Figure below . Q: What behavior includes all the ways that animals interact with each other and the environment? Choices: - adaptation - interdependence - instinct - animal behavior A:
Answer: animal behavior

Answer the following question given this paragraph: Figure 6.20 According to early accounts, Newton was inspired to make the connection between falling bodies and astronomical motions when he saw an apple fall from a tree and realized that if the gravitational force could extend above the ground to a tree, it might also reach the Sun. The inspiration of Newton's apple is a part of worldwide folklore and may even be based in fact. Great importance is attached to it because Newton's universal law of gravitation and his laws of motion answered very old questions about nature and gave tremendous support to the notion of underlying simplicity and unity in nature. Scientists still expect underlying simplicity to emerge from their ongoing inquiries into nature. Q: According to early accounts, newton was inspired to make the connection between falling bodies and astronomical motions when he saw an apple fall from a tree and realized that if the gravitational force could extend above the ground to a tree, it might also reach this? Choices: - stars - moon - horizon - sun A:
**Answer**
sun
Answer the following question given this paragraph: Eventually a main sequence star will use up all of its hydrogen. It then starts to fuse helium atoms into larger elements like carbon. At this time, the star's core will collapse inward. The star's outer layers will spread out and cool. The result is a larger star that is cooler on the surface, and red in color. The star is now a red giant . Q: When a star's core collapses inward while the outer layers spread and cool, what "colorful" celestial body forms? Choices: - blue giant - green giant - white giant - red giant A:
red giant
