Answer the following question given this paragraph: Echinoderms are named for their "spiny skin. " However, the spines aren't on their skin. They are part of the endoskeleton. The endoskeleton consists of calcium carbonate plates and spines, covered by a thin layer of skin. Adult echinoderms have radial symmetry. This is easy to see in the sea star and sand dollar in Figure above . However, echinoderms evolved from an ancestor with bilateral symmetry. Evidence for this is the bilateral symmetry of their larvae. Q: What type of organism, including sea stars and sand dollars, is named for their spiny skin? Choices: - mollusks - diatoms - chordates - echinoderms A:
echinoderms
Answer the following question given this paragraph: An example of a physical model is a drawing of the layers of Earth ( Figure below ). A drawing helps us to understand the structure of the planet. Yet there are many differences between a drawing and the real thing. The size of a model is much smaller, for example. A drawing also doesn't give good idea of how substances move. Arrows showing the direction the material moves can help. A physical model is very useful but it can't explain the real Earth perfectly. Q: What was diorite commonly used for in ancient civilizations? Choices: - school - currency - medicine - art A:
art
Q: Answer the following question given this paragraph: All waves are the way energy travels through matter. Ocean waves are energy traveling through water. They form when wind blows over the surface of the ocean. Wind energy is transferred to the sea surface. Then, the energy is carried through the water by the waves. Figure below shows ocean waves crashing against rocks on a shore. They pound away at the rocks and anything else they strike. Q: All waves are the way energy travels through what? Choices: - time - vacuums - space - matter A:
A: matter
Question: Answer the following question given this paragraph: Light with the longest wavelengths is called infrared light . The term infrared means "below red. " Infrared light is the range of light waves that have longer wavelengths and lower frequencies than red light in the visible range of light waves. The sun gives off infrared light as do flames and living things. You can't see infrared light waves, but you can feel them as heat. But infrared cameras and night vision goggles can detect infrared light waves and convert them to visible images. For a deeper understanding of infrared light, watch the video at this URL: http://www. youtube. com/watch?v=2--0q0XlQJ0 . Q: Light with the longest wavelengths is called what? Choices: - visible light - X-rays - UV light - infrared light A:
Answer: infrared light

Answer the following question given this paragraph: Mutations that occur in body cells cannot be passed on to offspring. They are confined to just one cell and its daughter cells. These mutations may have little effect on an organism. Q: Mutations cannot be passed on to offspring if they occur in what type of cells? Choices: - put cells - kept cells - blood cells - body cells A:
**Answer**
body cells
