Answer the following question given this paragraph: The topography of a region can be shown on a map. Topographic maps represent geographical features, such as hills and valleys. Topographic maps use contour lines to show geographical features. A contour line is a line of equal elevation. If you walk along a contour line, you will not go uphill or downhill. Topographic maps are also called contour maps. The rules of topographic maps are:. Q: On a topographic map, what is the term for a line of equal elevation? Choices: - latitude line - crater line - aurora line - contour line A:
**Answer**
contour line

Answer the following question given this paragraph: Angiosperms , or flowering plants, are the most abundant and diverse plants on Earth. Angiosperms evolved several reproductive adaptations that have contributed to their success. Like all vascular plants, their life cycle is dominated by the sporophyte generation. A typical angiosperm life cycle is shown in Figure below . Q: What are the most diverse plants on earth? Choices: - conifers - gymnosperms - grasses - angiosperms A:
**Answer**
angiosperms

Answer the following question given this paragraph: For an endothermic chemical reaction, energy is absorbed as reactants are converted to products. Exothermic and endothermic reactions can be thought of as having energy as either a product of the reaction or a reactant. Exothermic reactions give off energy, so energy is a product. Endothermic reactions require energy, so energy is a reactant. Q: Energy is absorbed as reactants are converted to products in what kind of chemical reaction? Choices: - anaphoric - hydrostatic - synthesis - endothermic A:
**Answer**
endothermic

Answer the following question given this paragraph: We see about six colors in a rainbowred, orange, yellow, green, blue, and violet; sometimes indigo is listed, too. Those colors are associated with different wavelengths of light, as shown in Figure 25.22. When our eye receives pure-wavelength light, we tend to see only one of the six colors, depending on wavelength. The thousands of other hues we can sense in other situations are our eye's response to various mixtures of wavelengths. White light, in particular, is a fairly uniform mixture of all visible wavelengths. Sunlight, considered to be white, actually appears to be a bit yellow because of its mixture of wavelengths, but it does contain all visible wavelengths. The sequence of colors in rainbows is the same sequence as the colors plotted versus wavelength in Figure 25.22. What this implies is that white light is spread out according to wavelength in a rainbow. Dispersion is defined as the spreading of white light into its full spectrum of wavelengths. More technically, dispersion occurs whenever there is a process that changes the direction of light in a manner that depends on wavelength. Dispersion, as a general phenomenon, can occur for any type of wave and always involves wavelength-dependent processes. Dispersion Dispersion is defined to be the spreading of white light into its full spectrum of wavelengths. Q: What is defined as the spreading of white light into its full spectrum of wavelengths? Choices: - immersion - saturation - combustion - dispersion A:
**Answer**
dispersion
