Answer the following question given this paragraph: Figure 9.3 Intervertebral Disc An intervertebral disc unites the bodies of adjacent vertebrae within the vertebral column. Each disc allows for limited movement between the vertebrae and thus functionally forms an amphiarthrosis type of joint. Intervertebral discs are made of fibrocartilage and thereby structurally form a symphysis type of cartilaginous joint. Q: What are intervertebral discs made of? Choices: - intercartilage - fibrotissue - connective cartilage - fibrocartilage A:
fibrocartilage

Answer the following question given this paragraph: Glaciers are melting back in many locations around the world. When a glacier no longer moves, it is called an ice sheet. This usually happens when it is less than 0.1 km2 in area and 50 m thick. Q: When a glacier no longer moves, what is it called? Choices: - a glacial lake - an iceberg - an ice cylinder - an ice sheet A:
(Answer)
an ice sheet
Ques: Answer the following question given this paragraph: An ecosystem is a group of living things and their environment. The word ecosystem is short for "ecological system. " Like any system, an ecosystem is a group of parts that work together. You can see examples of ecosystems in Figure below . The forest pictured is a big ecosystem. Besides trees, what living things do you think are part of the forest ecosystem? The dead tree stump in the same forest is a small ecosystem. It includes plants, mosses, and fungi. It also includes insects and worms. Q: A group of living things and their environment is called what? Choices: - community - population - biome - ecosystem A:
Ans: ecosystem

Answer the following question given this paragraph: Although the speed of light is constant in a vacuum, light travels at different speeds in different kinds of matter. For example, light travels more slowly in glass than in air. Therefore, when light passes from air to glass, it slows down. If light strikes a sheet of glass straight on, or perpendicular to the glass, it slows down but passes straight through. However, if light enters the glass at an angle other than 90, the wave refracts, or bends. This is illustrated in Figure below . How much light bends when it enters a new medium depends on how much it changes speed. The greater the change in speed, the more light bends. Q: While light travels at different speeds in different kinds of matter, the speed of light is constant in what condition? Choices: - outer space - through glass - under water - vacuum A:
(A).
vacuum
Ques:Answer the following question given this paragraph: 22.8 Torque on a Current Loop: Motors and Meters Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process. (See Figure 22.34. Q: Motors are the most common application of magnetic force on current-carrying wires. motors have loops of wire in this? Choices: - electrical circuit - capacitors - spark plugs - magnetic field A:

Ans:magnetic field
Answer the following question given this paragraph: Millions of fossils have been found since Darwin's time. They show that evolution may occur in fits and starts. Long period of little or gradual change may be interrupted by bursts of rapid change. The rate of evolution is influenced by how the environment is changing. Today, Earth's climate is changing rapidly. How do you think this might affect the rate of evolution?. Q: Fossil records show that what process may occur in "fits and starts"? Choices: - generation - isolation - variation - evolution A:
evolution
