Answer the following question given this paragraph: linked to a lower incidence of certain diseases. Thus, there have been an increasing number of recommendations by government bodies and health associations to decrease the proportion of saturated fat and increase the proportion of unsaturated fat in the diet. Most of these organizations also recommend decreasing the total amount of fat in the diet. Recently, certain fats called trans fats have been implicated in the presence of heart disease. These are fats from animal sources and are also produced when liquid oils are exposed to partial hydrogenation, an industrial process that increases their saturation. Trans fats are used in many prepared and fried foods. Because they bring with them the health risks that naturally occurring saturated fats do, there has been some effort to better quantify the presence of trans fats in food products. US law now requires that food labels list the amount of trans fat in each serving. Since 1992, the US Department of Agriculture has been promoting a food pyramid that gives a simple, visual picture of how much of what kind of foods make up a good, balanced diet. It recommends eating as few fats as possible. Although nutritionists recognize that some fat is necessary (and largely unavoidable, even by strict vegetarians), they emphasize that a large proportion of any fat, saturated or unsaturated, in the diet is unhealthy. Even so, a difference as simple as the difference between a single and double carboncarbon bond can have a significant impact on health. Q: What kind of fats have been implicated in the presence of heart disease? Choices: - plant fats - animal fats - key fats - trans fats A:
trans fats

Answer the following question given this paragraph: The cavities normally contain hydrated cations that are loosely bound to the oxygen atoms of the negatively charged framework by electrostatic interactions. The sizes and arrangements of the channels and cavities differ in different types of zeolites. For example, in zeolite A the aluminosilicate cages are arranged in a cubic fashion, and the channels connecting the cavities intersect at right angles. In contrast, the cavities in faujasite are much larger, and the channels intersect at 120 angles. In these idealized models, the oxygen atoms that connect each pair of silicon atoms have been omitted. Silicon and germanium react with nitrogen at high temperature to form nitrides(M3N4): Equation 22.26. Q: Silicon and germanium react with nitrogen at high temperature to form what? Choices: - oxides - carbonates - isotopes - nitrides A:
(Answer)
nitrides
Ques: Answer the following question given this paragraph: Blood cancers affect the production and function of your blood cells. Most of these cancers start in your bone marrow where blood is produced. In most blood cancers, the normal production of blood cells is replaced by uncontrolled growth of an abnormal type of blood cell. These abnormal blood cells are cancerous cells, and prevent your blood from performing many of its functions, like fighting off infections or preventing serious bleeding. Leukemia is a cancer of the blood or bone marrow. It is characterized by an abnormal production of blood cells, usually white blood cells. Lymphoma is a cancer of a type of white blood cell called lymphocytes. There are many types of lymphoma. Q: Lymphoma is a cancer of a type of what type of cells, called lymphocytes? Choices: - lung cells - brain cells - red blood cells - white blood cells A:
Ans: white blood cells

Answer the following question given this paragraph: Light with wavelengths shorter than visible light is called ultraviolet light . The term ultraviolet means "above violet. " Ultraviolet light is the range of light waves that have shorter wavelengths and higher frequencies than violet light in the visible range of light. With higher frequencies than visible light, ultraviolet light has more energy. It can be used to kill bacteria in food and to sterilize surgical instruments. The human skin also makes vitamin D when it is exposed to ultraviolet light. Vitamin D, in turn, is needed for strong bones and teeth. You can learn more about ultraviolet light and its discovery at this URL: http://www. youtube. com/watch?v=QW5zeVy8aE0. Q: What is light with wavelengths shorter than visible light called? Choices: - weathering light - infrared light - radio waves - ultraviolet light A:
(A).
ultraviolet light
Ques:Answer the following question given this paragraph: Water is heated in a boiler that burns a fuel such as natural gas or heating oil. The boiler converts the chemical energy stored in the fuel to thermal energy. Q: A boiler converts the chemical energy stored in fuel into what type of energy? Choices: - Thermometric Energy - ultraviolet energy - atmospheric energy - thermal energy A:

Ans:thermal energy
Answer the following question given this paragraph: Figure 25.5 Light is diffused when it reflects from a rough surface. Here many parallel rays are incident, but they are reflected at many different angles since the surface is rough. Q: What happens to light when it reflects from a rough surface? Choices: - reflects - becomes isolated - becomes concentrated - gets diffused A:
gets diffused
