Answer the following question given this paragraph: Air pollution is another significant cause of respiratory disease. The quality of the air you breathe can affect the health of your lungs. Asthma, heart and lung diseases, allergies, and several types of cancers are all linked to air quality. Air pollution is not just found outdoors; indoor air pollution can also be responsible for health problems. Q: Air pollution can cause disease of what system by affecting the health of your lungs? Choices: - excretory - digestive - cardiac - respiratory A:
respiratory

Answer the following question given this paragraph: Contour lines run next to each other. Each contour line is separated by a constant difference in elevation, usually noted on the map. Q: What type of lines run next to each other? Choices: - perpendicular lines - crater lines - fault lines - contour lines A:
(Answer)
contour lines
Ques: Answer the following question given this paragraph: A fluorescent light bulb produces visible light by fluorescence. Fluorescence occurs when a substance absorbs shorter-wavelength ultraviolet light and then gives off the energy as visible light. The compact fluorescent light bulb (CFL) in the Figure below contains mercury gas that gives off ultraviolet light when electricity passes through it. The inside of the bulb is coated with a substance called phosphor. Phosphor absorbs the ultraviolet light and then gives off most of the energy as visible light. Q: What light-producing process occurs when a substance absorbs shorter-wavelength ultraviolet light and then gives off the energy as visible light? Choices: - candescence - resistance - luminescence - fluorescence A:
Ans: fluorescence

Answer the following question given this paragraph: Bacteria are often used to make cheese from milk. But making foods is not the only beneficial role of bacteria. For example, they also play an essential role in your gut!. Q: Bacteria are often used to make cheese from what? Choices: - meat - egg - water - milk A:
(A).
milk
Ques:Answer the following question given this paragraph: Producers such as plants or algae use carbon dioxide in the air to make food. The organisms combine carbon dioxide with water to make sugar. They store the sugar as starch. Both sugar and starch are carbohydrates. Consumers get carbon when they eat producers or other consumers. Q: Sugar and starch are examples of what type of nutrient? Choices: - proteins - fat - vitamins - carbohydrates A:

Ans:carbohydrates
Answer the following question given this paragraph: Discussion The intensity goes up by a factor of 4 when the amplitude doubles. This answer is a little disquieting. The two individual waves each have intensities of 1.00 W/m 2 , yet their sum has an intensity of 4.00 W/m 2 , which may appear to violate conservation of energy. This violation, of course, cannot happen. What does happen is intriguing. The area over which the intensity is 4.00 W/m 2 is much less than the area covered by the two waves before they interfered. There are other areas where the intensity is zero. The addition of waves is not as simple as our first look in Superposition and Interference suggested. We actually get a pattern of both constructive interference and destructive interference whenever two waves are added. For example, if we have two stereo speakers putting out 1.00 W/m 2 each, there will be places in the room where the intensity is 4.00 W/m 2 , other places where the intensity is zero, and others in between. Figure 16.45 shows what this interference might look like. We will pursue interference patterns elsewhere in this text. Q: Two types of interference found in waves are constructive and what else? Choices: - osmotic - conductive - primitive - destructive A:
destructive
