Answer the following question given this paragraph: Some places inside Earth are so hot that rock melts. Melted rock inside the Earth is called magma. Magma can be hotter than 1,000 o C. When magma erupts onto Earth's surface, it is known as lava ( Figure below ). Minerals form when magma and lava cool. Some minerals crystallize at hotter temperatures. These minerals form first. Other minerals form at cooler temperatures. These minerals form later. Q: What is the term for magma that erupts onto earth's surface? Choices: - debris - obsidian - steam - lava A:
lava

Answer the following question given this paragraph: Magnetism is the ability to be attracted by a magnet and to act as a magnet. Only ferromagnetic materials have this property. They include iron, cobalt, and nickel. When these materials are magnetized, they become temporary or permanent magnets. Magnetite is a natural permanent magnet. Q: What is the ability to be attracted by a magnet and to act as a magnet? Choices: - electrical attraction - polarization - inertia - magnetism A:
(Answer)
magnetism
Ques: Answer the following question given this paragraph: Composition of Body Fluids The compositions of the two components of the ECFplasma and IFare more similar to each other than either is to the ICF (Figure 26.5). Blood plasma has high concentrations of sodium, chloride, bicarbonate, and protein. The IF has high concentrations of sodium, chloride, and bicarbonate, but a relatively lower concentration of protein. In contrast, the ICF has elevated amounts of potassium, phosphate, magnesium, and protein. Overall, the ICF contains high concentrations of potassium and phosphate ( HPO 24 ), whereas both plasma and the ECF contain high concentrations of sodium and chloride. Q: What are the two components of the ecf? Choices: - proteins and if - polymer and if - solids and if - plasma and if A:
Ans: plasma and if

Answer the following question given this paragraph: Ice caps are areas covered with thick ice year round. Ice caps are found only in Greenland and Antarctica. Temperatures and precipitation are both very low. What little snow falls usually stays on the ground. It doesn't melt because it's too cold. Q: Ice caps are found only in greenland and which other place? Choices: - the tundra - Siberia - rainforests - antarctica A:
(A).
antarctica
Ques:Answer the following question given this paragraph: Occipital Bone The occipital bone is the single bone that forms the posterior skull and posterior base of the cranial cavity (Figure 7.9; see also Figure 7.8). On its outside surface, at the posterior midline, is a small protrusion called the external occipital protuberance, which serves as an attachment site for a ligament of the posterior neck. Lateral to either side of this bump is a superior nuchal line (nuchal = "nape" or "posterior neck"). The nuchal lines represent the most superior point at which muscles of the neck attach to the skull, with only the scalp covering the skull above these lines. On the base of the skull, the occipital bone contains the large opening of the foramen magnum, which allows for passage of the spinal cord as it exits the skull. On either side of the foramen magnum is an oval-shaped occipital condyle. These condyles form joints with the first cervical vertebra and thus support the skull on top of the vertebral column. Q: What is the single bone that forms the posterior skull and posterior base of the cranial cavity? Choices: - limbic bone - maxilla - radiating bone - occipital bone A:

Ans:occipital bone
Answer the following question given this paragraph: A mineral deposit that contains enough minerals to be mined for profit is called an ore . Ores are rocks that contain concentrations of valuable minerals. The bauxite shown in the Figure below is a rock that contains minerals that are used to make aluminum. Q: What type of rock contains concentrations of valuable minerals? Choices: - sedimentary - igneous - metamorphic - ores A:
ores
