Answer the following question given this paragraph: Cells are the building blocks of life. This is clear from the photo in Figure below . It shows stacks upon stacks of cells in an onion plant. Cells are also the basic functional units of living things. They are the smallest units that can carry out the biochemical reactions of life. No matter how different organisms may be from one another, they all consist of cells. Moreover, all cells have the same basic parts and processes. Knowing about cells and how they function is necessary to understanding life itself. Q: What are the building blocks of life? Choices: - muscles - seeds - bricks - cells A:
cells
Answer the following question given this paragraph: A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Each bacterium is a single cell. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid together with a variety of tiny functioning units called organelles. In humans, as in all organisms, cells perform all functions of life. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body. This book covers eleven distinct organ systems in the human body (Figure 1.4 and Figure 1.5). Assigning organs to organ systems can be imprecise since organs that "belong" to one system can also have functions integral to another system. In fact, most organs contribute to more than one system. Q: What is the smallest independently functioning unit of a living organism? Choices: - proteins - molecule - atom - cell A:
cell
Q: Answer the following question given this paragraph: Q: Most plants grow continuously, except for what periods? Choices: - abnormal - mutant - winter - dormant A:
A: dormant
Question: Answer the following question given this paragraph: Rainbows are produced by a combination of refraction and reflection. You may have noticed that you see a rainbow only when you look away from the sun. Light enters a drop of water and is reflected from the back of the drop, as shown in Figure 25.24. The light is refracted both as it enters and as it leaves the drop. Since the index of refraction of water varies with wavelength, the light is dispersed, and a rainbow is observed, as shown in Figure 25.25 (a). (There is no dispersion caused by reflection at the back surface, since the law of reflection does not depend on wavelength. ) The actual rainbow of colors seen by an observer depends on the myriad of rays being refracted and reflected toward the observer's eyes from numerous drops of water. The effect is most spectacular when the background is dark, as in stormy weather, but can also be observed in waterfalls and lawn sprinklers. The arc of a rainbow comes from the need to be looking at a specific angle relative to the direction of the sun, as illustrated in Figure 25.25 (b). (If there are two reflections of light within the water drop, another "secondary" rainbow is produced. This rare event produces an arc that lies above the primary rainbow arcsee Figure 25.25 (c). ) Rainbows Rainbows are produced by a combination of refraction and reflection. Q: What colorful arc-shaped atmospheric phenomena are produced by a combination of refraction and reflection? Choices: - lightning - shadows - sunsets - rainbows A:
Answer: rainbows
*Question*
Answer the following question given this paragraph: If a solute is a solid or liquid, increasing the temperature increases its solubility. For example, more sugar can dissolve in hot water than in cold water. Q: What does increasing a solute's temperature do? Choices: - increases its viscosity - decrease its solubility - no change - increases its solubility A:
**Answer**
increases its solubility
Q: Answer the following question given this paragraph: Tellurium is a silvery white, brittle metalloid. It is toxic and may cause birth defects. Tellurium can conduct electricity when exposed to light, so it is used to make solar panels. It has several other uses as well. For example, it makes steel and copper easier to work with and lends color to ceramics. Q: What color is the brittle metalloid tallurium? Choices: - brownish black - purplish blue - yellowish green - silvery white A:
A: silvery white
