Answer the following question given this paragraph: Anatomy of a Tooth The teeth are secured in the alveolar processes (sockets) of the maxilla and the mandible. Gingivae (commonly called the gums) are soft tissues that line the alveolar processes and surround the necks of the teeth. Teeth are also held in their sockets by a connective tissue called the periodontal ligament. The two main parts of a tooth are the crown, which is the portion projecting above the gum line, and the root, which is embedded within the maxilla and mandible. Both parts contain an inner pulp cavity, containing loose connective tissue through which run nerves and blood vessels. The region of the pulp cavity that runs through the root of the tooth is called the root canal. Surrounding the pulp cavity is dentin, a bone-like tissue. In the root of each tooth, the dentin is covered by an even harder bone-like layer called cementum. In the crown of each tooth, the dentin is covered by an outer layer of enamel, the hardest substance in the body (Figure 23.11). Although enamel protects the underlying dentin and pulp cavity, it is still nonetheless susceptible to mechanical and chemical erosion, or what is known as tooth decay. The most common form, dental caries (cavities) develops when colonies of bacteria feeding on sugars in the mouth release acids that cause soft tissue inflammation and degradation of the calcium crystals of the enamel. The digestive functions of the mouth are summarized in Table 23.4. Q: What secures teeth in the mouth? Choices: - plug - muscles - cartilage - socket A:
socket
Q: Answer the following question given this paragraph: Fossil fuels are mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms. They include petroleum (commonly called oil), natural gas, and coal. Fossil fuels provide most of the energy used in the world today. They are burned in power plants to produce electrical energy, and they also fuel cars, heat homes, and supply energy for many other purposes. You can see examples of their use in Figure below . Q: What is the common name of mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms? Choices: - fossil record - renewable resources - non-renewable fuel - fossil fuels A:
A: fossil fuels
Question: Answer the following question given this paragraph: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. Q: What weather phenomenon increases the rate of weathering in rock and soil? Choices: - temperature - earthquake - landslide - rainfall A:
Answer: rainfall

Answer the following question given this paragraph: The Kyoto Protocol is another worldwide agreement on air pollution. It was passed in 1997. The Protocol focuses on controlling greenhouse gas emissions. Its aim is to control global warming. Q: What does the kyoto protocol focus on controlling? Choices: - carbonate gas emissions - Helium emissions - Ozone emissions - greenhouse gas emissions A:
**Answer**
greenhouse gas emissions

Answer the following question given this paragraph: Saturn's largest moon, Titan, is about one and a half times the size of Earth's moon. Titan is even larger than the planet Mercury. The picture below compares the size of Titan to Earth ( Figure below ). Scientists are very interested in Titan. The moon has an atmosphere that is thought to be like Earth's first atmosphere with nitrogen and methane. This atmosphere was around before life developed on Earth. Like Jupiter's moon, Europa, Titan may have a layer of liquid water under a layer of ice. Scientists now think that there are lakes on Titan's surface. Don't take a dip, though. These lakes contain liquid methane and ethane instead of water! Methane and ethane are compounds found in natural gas. Q: Europa and titan are names of what kind of celestial objects? Choices: - galaxies - stars - asteroids - moons A:
(A).
moons
