The Effects of Junk Food on Health Junk foods are deemed to be trash foods as they are high in fat‚ sodium and sugar. The apparent effect of junk food can lead to obesity and a range of attendant health problems‚ including diabetes‚ heart disease and arthritis. Majority of junk food choices do not deliver beneficial nutritional values. Here are the facts about how excessive junk food consumption affects your body. First of all‚ junk food doesn’t contain the nutrients your body needs to stay

can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

IS GENETICALLY MODIFIED FOODS REALLY SAFE AS WE THINK ? Since the beginning of life‚ nourishment is the first requirement for all kind of alive. According to Chassy (2007)‚ early humans lived a hunter gatherer lifestyle and that around 10000 years ago they started to transition into an agricultural lifestyle. Also they feed animals to their milk‚ meat and eggs. Later‚ some people interested in agriculture in order to survive and earn money. In today’s world‚ technological developments

Effects of Eating Fast Food We are constantly looking for ways to make the daily obligations and our daily routine as fast as possible. It is common that people complain that they do not have enough time to prepare food at home; different solutions have emerged to make life easier‚ such as fast food. It has an affordable price‚ an attractive presentation‚ and we can find it everywhere. Also‚ has adapted to a new lifestyle and has achieved worldwide popularity. But fast food has some negative effects

Title: pH and buffer solutions Aim This experiment was carried out to determine the role of buffer solution and the factor which affect the buffer capacity. Besides‚ this experiment was carried out to investigate the solubility of protein casein over a range of pH concentration. This experiment also was carried out to determine the isoelectric point of the casein and the effect of the isoelectric point toward the casein solution. Methods Verification of the Henderson-Hasselbalch equation

SLII The effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water

------------------------------------------------- COLORIMETRIC DETERMINATION OF pH ------------------------------------------------- Abstract This experiment examined the result of the various color indicators combined with different buffer solution‚ thereby testing the precision and accuracy of determining the pH value colorimetrically. Colorimetric method is a simple and practical procedure with an important advantage: they do not get out of order as from time to time do the pH-meters. Four buffers (Acetate buffer‚ phosphate

population was approximately 6.7 billion. It is projected to increase to 9.2 billion by 2050. With this many people in the world you need a substantial amount of food to feed them. But‚ this leads to a problem in the food industry. Animals do not grow fast enough in order to meet these high demands. In order to compensate for the lack of supply of food the farmers need to somehow make their animals grow faster. For the solution they introduced the use of hormones. These hormones include estradiol‚ progesterone

CAUSE AND EFFECT ON GM FOODS I have selected to research and write about the potential dangers and benefits of genetically modified (GM) foods. Genetically modified foods are produced from organisms that have had specific changes introduced into their DNA using methods of genetic engineering. These techniques have allowed far greater control over food’s genetic structure than past methods like selective breeding. Genetically modified foods were introduced commercially for sale in 1994.

II: Titration with a pH Meter 1. Fill the 50-milliliter buret with a 0.25 molar NaOH solution. 2. Record volume. 3. Measure out between 20 milliliters and 40 milliliters of the unknown HCl solution. This amount must be different than the amount used in part I. 4. Record volume. 5. The amount of unknown HCl is then added to the 100-milliliter Erlenmeyer flask. 6. Insert the pH meter into the Erlenmeyer flask and record the initial pH of the acid. Remember to record the pH of the solution after
