Should there be limits to genetic modification of food? Should there be limits to genetic modification of food? It may seem very attractive to be able to genetically modify crops‚ but at what cost? Giant transnational companies are carrying out a dangerous global experiment by introducing large numbers of genetically engineered food into our diet. Genetic manipulations can result in unanticipated harmful effects‚ and because genetically engineered foods are not tested sufficiently‚ this experiment

pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and

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

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

analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels may change if other solutions are added‚ we can tell what the pH will be based on its colour. Solutions called buffers change the pH levels of

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. No thorough

The first effect of eating Junk Food is its impact on energy levels. Many people skip breakfast and other important meals choosing instead to grab a quick snack or soft drink. Junk Food is an informal term for food that is of little nutritional value and often high in fat‚ sugar‚ and calories. It is widely believed that the term was coined by Michael Jacobson‚ director of the Center for Science in the Public Interest in 1972. Junk Foods typically contain High levels of calories from sugar or fat

Similar to potassium‚ sodium is a major mineral‚ however‚ unlike potassium which maintains fluid and electrolyte balance inside the cell‚ sodium is a major part of the body’s fluid and electrolyte balance system because it is the chief ion used to maintain the volume of fluid outside cells. Sodium also helps maintain acid-base balance and is essential to muscle contraction and nerve transmission. The DRI recommended intakes for sodium for adults ages 19 to 50 years old is 1‚500 milligrams per day

Bad Effect Of Fast Food When you feel like eating something and think of food‚ the things come to mind first are the taste‚ odor or color. Those who have to look after their weight will think of the portion size‚ many others think of energy‚ fats‚ sugars‚ vitamins or minerals. But do you know that the food we eat may cause side effects and a list of disadvantages. We are not talking about spoiled or poor quality food. Freshly harvested or just cooked food may also cause side effects‚ some are
