One of the biggest disadvantages is not being able to make connections as easy as the copper. Fiber optic cables have a core as fine as a human hair, making it extremely difficult to splice. Copper cables are obviously not going to be around forever with the fiber optics being so futuristic, but they still have advantages over the fiber. Copper is very easy to work with. When making connections it is so much easier to splice the copper cable than it would be for the fiber.
Vitamins A, D, E, and K are fat soluble. (Young & Anderson, 2008) Vitamin A plays an important role in many bodily functions such as bone growth, cell division, reproduction, vision, and gene expression. The eyes and skin, as well as mucus membranes in the nose, mouth throat and lungs also require vitamin A for moisture. Good sources of vitamin A include dairy products, liver, and fish. Beta carotene, which is found in fruits and vegetables, can be converted by the body into vitamin A.
Saliva tests are a little more expensive than urine testing and considered a relatively intrusive method of drug testing, therefore becoming more commonly used by employers. Saliva tests have no nationally accepted standards of cut-off concentrations for detection which could make the results less reliable and/or acceptable for legal cases. Hair tests are even more expensive but are still considered a relatively intrusive method of drug testing and can detect substance use over a longer period of time, but usually cannot detect use within the past week. Hair tests require a small amount of hair clippings. Hair test are considered more accurate than the urine tests.
1a) Explain the classification of the selected energy resources shown. This resource shows the environmental impacts, social acceptability and economic costs of a select few energy sources. They are classified in this way for a number of reasons. Nuclear power is shown to have high economic costs, this is because it is very expensive to build and decommission nuclear power stations, it also an expensive process to mine, process and enrich uranium and plutonium required as nuclear fuel. Nuclear waste must also be stored for a very long period adding to the cost.
Cholesterol is a fat like substance made mostly by the liver. It is also found in some food such as dairy, meat, and eggs. Your body needs cholesterol to help digest
Beverages known as sport drinks contain electrolytes to maintain mineral balance as well as sugar for energy. These drinks are good for athletes, but should not be consumed by people who sit all day (Lewandowski, 2003). However, in most people, their regular diet provides an excess of sodium while not including enough potassium (Grosvenor & Smolin, 2006). Sport drinks are often confused with energy beverages since they are usually displayed next to each other in convenience stores. This can be a deadly mistake if a large amount of the energy beverage is consumed.
Protein is needed in the diet for growth and repair of the body. Protein protects the body form infections and disease. Protein is also a good source of some vitamins and minerals. The best foods to be included in the diet to get protein into your body would be dairy products, meat, fish and eggs. Carbohydrates is needed in the diet for energy and warmth, once there is carbohydrates in the body it keep us going throughout the day.
Over the past 20 years, CLA supplementation has produced positive effects in animal studies, such as significant body fat reduction, anticarcinogenisis, antiatherogenesis, immune modulation and improved bone health. Conversely, human studies have not produced all of the aforementioned results. Nonetheless, there have been many human studies supporting a minimal but significant body fat reduction. These results have been mainly attained with a 50:50 mixture of cis-9, trans-11 and trans-10, cis-12 of purified CLA isomers at various doses. There is evidence indicating that a dose of 3.0g CLA/day may lead to fat loss, whereas the average Canadian consumes between 0.1-1.5 g CLA/day.
High–protein diets not only limit some calcium sources, they can cause the body to lose calcium. * Constipation—MS can contribute to chronic constipation. A diet rich in fiber and fluids, along with exercise, is important to help manage this problem. Long-term safety The verdict is still out on the long-term safety of low-carb diets. They tend to be high in total fat, especially saturated animal fat, which has been linked to heart disease, cancer, and perhaps even MS.
Most weight loss programs will not work without an exercise routine along with a structured diet plan. This is because exercise is the best way to burn calories, which is the gateway to burning fat. As many people can notice, most of America does not exercise, because if they did, one-third of adults in America would not be considered obese (CDC). There have been many studies on how exercise can decrease the risk of some diseases and other conditions. Being active can increase levels of HDL, the good cholesterol.
