Answer the following question given this paragraph: A concave lens is thicker at the edges than it is in the middle. You can see the shape of a concave lens in the Figure below . From the diagram, it's clear that the lens causes rays of light to diverge, or spread apart, as they pass through it. Note that the image formed by a concave lens is on the same side of the lens as the object. It is also smaller than the object and right-side up. However, it isn't a real image. It is a virtual image. Your brain "tricks" you into seeing an image there. The light rays actually pass through the glass to the other side and spread out in all directions.

Q: A lens of what shape causes rays of light to diverge, or spread apart, as they pass through it? Choices: - convex - flat - elongated - concave A:
concave

Answer the following question given this paragraph: Subgroups of the mammals include rodents, carnivores, insectivores, bats, and primates. Q: What class of animals includes the subgroups rodents, carnivores, insectivores, bats, and primates? Choices: - insects - reptiles - amphibians - mammals A:
(Answer)

Ques: Answer the following question given this paragraph: Katabatic winds move the same way as mountain and valley breezes. However, they are much stronger. Katabatic winds form over a high plateau that is surrounded by mountains. In winter, the plateau grows cold. Air sinks through the gaps in the mountains. Over Antarctica and Greenland, these winds are frigid. Q: What type of winds move the same way as mountain and valley breezes? Choices: - pyroclastic winds - planetary winds - prevailing winds - katabatic winds A:
Ans: katabatic winds
(Q).
Answer the following question given this paragraph: It is actually the Yellow Christmas tree worm. These animals are colorful, and can be red, orange, yellow, blue, and white. The Christmas tree worm lives on tropical coral reefs throughout the world. The Christmas tree worm's plumes are used for feeding and respiration. These worms use their plumes to catch plankton and other small particles passing in the water. Cilia then pass the food to the worm's mouth. Q: Where does the christmas tree worm live? Choices: - northeast coral reefs - Atlantic shoreline - rainforests - tropical coral reefs A:
(A).
tropical coral reefs
Ques:Answer the following question given this paragraph: This equation for kinetic energy shows that velocity affects kinetic energy more than mass does. For example, if mass doubles, kinetic energy also doubles. But if velocity doubles, kinetic energy increases by a factor of four. That's because velocity is squared in the equation. You can see for yourself how mass and velocity affect kinetic energy by working through the problems below. Q: Velocity affects what type of energy more than mass does? Choices: - magnetic energy - harmonic energy - mechanical energy - kinetic energy A:

Ans:kinetic energy
Question: Answer the following question given this paragraph: Diseases of the respiratory system include asthma, pneumonia, and emphysema. Q: Asthma, pneumonia, and emphysema are diseases of what system? Choices: - reproductive - pulmonary - digestive - respiratory A:
Answer:
respiratory
