Answer the following question given this paragraph: In the chest, the trachea divides as it enters the lungs to form the right and left bronchi . The bronchi contain cartilage, which prevents them from collapsing. Mucus in the bronchi traps any remaining particles in air. Tiny, hair-like structures called cilia line the bronchi and sweep the particles and mucus toward the throat so they can be expelled from the body. Q: In the chest, the trachea divides as it enters the lungs to form the right and left what? Choices: - alveoli - ventricle - atrium - bronchi A:
bronchi
Answer the following question given this paragraph: The simplest organic compounds are those composed of only two elements: carbon and hydrogen. These compounds are called hydrocarbons. Hydrocarbons themselves are separated into two types: aliphatic hydrocarbons and aromatic hydrocarbons. Aliphatic hydrocarbons are hydrocarbons based on chains of C atoms. There are three types of aliphatic hydrocarbons. Alkanes are aliphatic hydrocarbons with only single covalent bonds. Alkenes are hydrocarbons that contain at least one CC double bond, and alkynes are hydrocarbons that contain a CC triple bond. Occasionally, we find an aliphatic hydrocarbon with a ring of C atoms; these hydrocarbons are calledcycloalkanes (or cycloalkenes or cycloalkynes). Aromatic hydrocarbons have a special six-carbon ring called a benzene ring. Electrons in the benzene ring have special energetic properties that give benzene physical and chemical properties that are markedly different from alkanes. Originally, the term aromatic was used to describe this class of compounds because they were particularly fragrant. However, in modern chemistry the term aromatic denotes the presence of a six-membered ring that imparts different and unique properties to a molecule. The simplest alkanes have their C atoms bonded in a straight chain; these are callednormal alkanes. They are named according to the number of C atoms in the chain. The smallest alkane is methane:. Q: The simplest organic compounds have hydrogen and what else? Choices: - sodium - oxygen - nitrogen - carbon A:
carbon
Q: Answer the following question given this paragraph: Major grocery stores in the United States are organized into departments, such as dairy, meats, produce, bread, cereals, and so forth. Each aisle contains hundreds, if not thousands, of different products for customers to buy and consume (Figure 5.4). Although there is a large variety, each item links back to photosynthesis. Meats and dairy products link to photosynthesis because the animals were fed plant-based foods. The breads, cereals, and pastas come largely from grains, which are the seeds of photosynthetic plants. What about desserts and drinks? All of these products contain sugarthe basic carbohydrate molecule produced directly from photosynthesis. The photosynthesis connection applies to every meal and every food a person consumes. Q: Meats and dairy products link to photosynthesis because the animals were fed what? Choices: - carnivorous diets - chloroplasts - biofuel - plant-based foods A:
A: plant-based foods
Question: Answer the following question given this paragraph: Electromagnets find use in many practical applications. Electromagnets are used to lift large masses of magnetic materials such as scrap iron, rolls of steel, and auto parts. Q: What are used to lift large masses of magnetic materials such as scrap iron, rolls of steel, and auto parts? Choices: - Glue - Tape - screws - electromagnets A:
Answer: electromagnets

Answer the following question given this paragraph: At each level of a food chain, a lot of energy is lost. Only about ten percent of the energy passes to the next level. Where does that energy go? Some energy is given off as heat. Some energy goes into animal wastes. Energy also goes into growing things that another consumer can't eat, like fur. It's because so much energy is lost that most food chains have just a few levels. There's not enough energy left for higher levels. Q: Loss of energy is the reason that what typically has few levels? Choices: - humans - the atmosphere - video games - food chain A:
**Answer**
food chain
Q: Answer the following question given this paragraph: Liquids with strong intermolecular forces have higher surface tensions than liquids with weaker forces. Q: Liquids with strong intermolecular forces have higher what than liquids with weaker forces? Choices: - temperature - melting point - freezing point - surface tension A:
A: surface tension
