Naomi Ruiz Vitamin D Paper Dear Grandfather‚ After doing extensive research on the extremely controversial and confusing topic of how much vitamin D a person needs I have become much more knowledgeable on the subject. Allow me to enlighten you by first explaining exactly what vitamins are and what they do for your body. According to the book Vitamins‚ vitamins are a group of organic compounds which are essential in very small amounts for the normal functioning of the body (Ball 2004). In the article

* Hypothesis The vitamin C content will be fewer in the cooked green pepper than the one hasn’t * Objective To investigate the effect of heating on the vitamin C content of green pepper. * Background (copy from the task sheet)and Biological principle * All fruits and vegetables contain a certain amount of vitamin C; also called ascorbic acid is a water-soluble vitamin that is necessary for normal growth and development. * the cooking process of green pepper will decrease the concentration

Titration test Alfredo Verzo III We have been provided with two samples of vinegar‚ one removed from a restaurant and one removed from a take-away. Trading Standards suspect these two establishments of watering down the vinegar. They need evidence that the samples contain less acid than the standard vinegar sample provided. What is the purpose of this? I’m a worker in the Trading Standards which carries out tests to see if restaurants and takeaways are watering down the vinegar. We will

1. Before C&C’s reorganization‚ why was its performance poor? To examine the poor performance before C&C’s reorganization‚ it’s essential to look at the structural and contextual dimension in the organization. This approach helps to reveal what the problems were‚ and where the problems arose in the organization. (Daft‚ 2010:20) C&C’s structural dimensions before the reorganization First of all‚ C&C had a tall organization‚ with narrow spans of control and centralized authority. The authority

An Introduction to Titration: Standardization of HCl and NaOH Lab Report Introduction: It is important to standardize solutions in order to have the accurate amount of concentration known. A standard solution can be prepared in either of two ways: A primary standard is carefully weighed‚ dissolved‚ and diluted accurately to a known volume. Its concentration can be calculated from this data. A solution is made to an approximate concentration and then standardized by titrating an accurately weighed

experiment is to determine the concentration of acetic acid in vinegar by using 0.1 M HCl and NaOH solution. By performing three titrations to determine the concentration of the base‚ the concentration of the acid was determined to be 0.600 M. It was possible to determine its concentration by standardizing the sodium hydroxide solution used for the first three titrations and by using phenolphthalein to indicate its equivalence point. In conclusion‚ although there were sources of error‚ the hypothesis

Criterion C: Taking action My goal in this project‚ was learning how to compose a song and combine creativity‚ to result in an original piece of music that shares my personal beliefs‚ values‚ and emotions that others will also be able to connect. To bring this goal to life‚ I went into a further theory to understand its relation to the global context chosen. By doing this‚ I was able to make a start on playing with chords on the piano‚ based on the theme‚ pitch‚ and genre. Indeed‚ coming up with

Hepatitis C is a liver disease that is caused by hepatitis C virus. The virus enters into the liver cell‚ use the cell’s genetic to make copies of itself which then affects more cells. Causes Hepatitis C is usually transmitted through blood to blood contacts. It can be transmitted by sharing needles when injecting‚ toothbrushes and razors‚ tattoo or body piercing with equipment that has not been properly sterilized. It can also be sexually transmitted. It is not passed on by everyday contact

Water-Soluble and Fat-Soluble Vitamins Fat and Water-Soluble Vitamins The vitamin classification is defined as water-soluble vitamins and fat-soluble vitamins. Vitamins are an important part of our diet‚ as they help with bodily functions and provide defense mechanisms for our immune system. You only need very small quantities but if you don ’t get enough your body cannot function optimally. Severe deficiencies cause debilitating diseases but even marginal intakes can cause subtle changes
