Answer the following question given this paragraph: In a longitudinal wave, amplitude is a measure of how compressed particles of the medium become when the wave passes through. The closer together the particles are, the greater the amplitude. Q: In a longitudinal wave, what term is a measure of how compressed particles of the medium become when the wave passes through? Choices: - magnitude - frequency - voltage - amplitude A:
amplitude
Answer the following question given this paragraph: An atomic bomb explodes and generates a huge mushroom cloud. The tremendous energy released when the bomb explodes is incredibly destructive. Where does all the energy come from? The answer is the nucleus of the atom. Q: Where does the energy from an atomic bomb come from? Choices: - isotope of atom - electron shell - neutron - nucleus of atom A:
nucleus of atom
Q: Answer the following question given this paragraph: The pointed pattern is a form of partial albinism, which results from a mutation in an enzyme that is involved in melanin production. The mutated enzyme is heat-sensitive; it fails to work at normal body temperatures. However, it is active in cooler areas of the skin. This results in dark coloration in the coolest parts of the cat's body, such as the lower limbs and the face, as shown in Figure above . The cat's face is cooled by the passage of air through the nose. Generally adult Siamese cats living in warm climates have lighter coats than those in cooler climates. Q: Partial albinism results from a mutation in an enzyme that is involved in the production of what? Choices: - cytoplasm - hair - cancer - melanin A:
A: melanin
Question: Answer the following question given this paragraph: Star clusters are small groups of stars. A star cluster is smaller than a galaxy. There are two main types, open clusters and globular clusters. Both types are held together by gravity. Q: What force holds together both types of star clusters? Choices: - weight - magnetism - inertia - gravity A:
Answer: gravity

Answer the following question given this paragraph: Biodiversity is a measurement of the amount of variation of the species in a given area. More specifically, biodiversity can be defined as the variety of life and its processes, including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. Q: What is a measurement of the amount of variation of the species in a given area called? Choices: - ecosystem - population - degradation - biodiversity A:
**Answer**
biodiversity
(Q).
Answer the following question given this paragraph: Earth's crust contains a lot of oxygen. The oxygen can combine with other elements to create oxide minerals. Oxides contain one or two metal elements combined with oxygen. Oxides are different from silicates, because they do not contain silicon. Many important metals are found as oxides. For example, hematite and magnetite are both oxides that contain iron. Hematite (Fe 2 O 3 ) has a ratio of two iron atoms to three oxygen atoms. Magnetite (Fe 3 O 4 ) has a ratio of three iron atoms to four oxygen atoms. Notice that the word "magnetite" contains the word "magnet. " Magnetite ( Figure below ) is a magnetic mineral. Q: What layer of earth contains abundant oxygen, which can combine with other elements to create oxide minerals? Choices: - the core - the surface - the tectonic plates - the crust A:
(A).
the crust
