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

Answer the following question given this paragraph: Homeostasis, or the maintenance of constant conditions in the body, is a fundamental property of all living things. In the human body, the substances that participate in chemical reactions must remain within narrows ranges of concentration. Too much or too little of a single substance can disrupt your bodily functions. Because metabolism relies on reactions that are all interconnected, any disruption might affect multiple organs or even organ systems. Water is the most ubiquitous substance in the chemical reactions of life. The interactions of various aqueous solutionssolutions in which water is the solventare continuously monitored and adjusted by a large suite of interconnected feedback systems in your body. Understanding the ways in which the body maintains these critical balances is key to understanding good health. Q: The maintenance of constant conditions in the body is also known as what? Choices: - consciousness - mononucleosis - hypothesis - homeostasis A:
**Answer**
homeostasis

Answer the following question given this paragraph: Q: Platelets play a role in what cascade of reactions that converts plasma fibrinogen to fibrin? Choices: - hemophilia - sickle cell anemia - bleeding - blood clotting A:
**Answer**
blood clotting

Answer the following question given this paragraph: Roundworms may be free-living or parasitic organisms. Free-living worms are found mainly in freshwater habitats. Some live in moist soil. They generally feed on bacteria, fungi, protozoa, or decaying organic matter. By breaking down organic matter, they play an important role in the carbon cycle. Q: By breaking down organic matter, roundworms play an important role in which cycle? Choices: - water cycle - metamorphic cycle - circadian cycle - carbon cycle A:
**Answer**
carbon cycle
