Answer the following question given this paragraph: Although the idea that Earth is a magnet is centuries old, the discovery of why Earth is a magnet is a relatively new. In the early 1900s, scientists started using seismographic data to learn about Earth's inner structure. A seismograph detects and measure earthquake waves. Evidence from earthquakes showed that Earth has a solid inner core and a liquid outer core (see the Figure below ). The outer core consists of molten metals, mainly iron and nickel. Scientists think that Earth's magnetic field is generated by the movement of charged particles through these molten metals in the outer core. The particles move as Earth spins on its axis. The video at the URL below takes a closer look at how this occurs. Q: What device detects and measuresee earthquake waves? Choices: - stenograph - polygraph - sphygmomanometer - seismograph A:
seismograph
Q: Answer the following question given this paragraph: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points. Q: What is the general name for saturated hydrocarbons? Choices: - petrolatums - enzymes - halides - alkanes A:
A: alkanes
Question: Answer the following question given this paragraph: Of all vertebrates, mammals have the biggest and most complex brain for their body size (see Figure below ). The front part of the brain, called the cerebrum , is especially large in mammals. This part of the brain controls functions such as memory and learning. Q: In a mammal the front part of the brain is called the what? Choices: - cerebellum - thallus - brain stem - cerebrum A:
Answer: cerebrum

Answer the following question given this paragraph: Ground type. Solid bedrock vibrates less than soft sediments, so there is less damage on bedrock. Sometimes sediments become saturated with water. They then undergo liquefaction and become like quicksand ( Figure below ). Soil on a hillside may become a landslide. Q: Solid bedrock vibrates less and therefore does less of what to bedrock? Choices: - block - dampen - butress - damage A:
**Answer**
damage

Answer the following question given this paragraph: Today, fungi are no longer classified as plants. We now know that they have unique physical, chemical, and genetic traits that set them apart from plants (and other eukaryotes). For example, the cell walls of fungi are made of chitin, not cellulose. Also, fungi absorb nutrients from other organisms, whereas plants make their own food. These are just a few of the reasons fungi are now placed in their own kingdom. Q: The cell walls of fungi are made of what? Choices: - lectin - mucous - cartilage - chitin A:
(Answer)
chitin
