Caralee Layne Al Maginnes English 111-4136 September 12, 2014 What you really need to know about the advances in Reproductive Technology Germline genetic engineering raises ethical questions such as reproductive rights and germinal choice. In the essay “Designer Genes” Bill McKibben provides facts and details about genetic technology, and he explains that the decision to approve this kind of technology is in the hands of our present generation. McKibben takes issue with genetically modifying the genes of one’s offspring, and he says that people use genetic engineering “simply to enhance their children’s looks or intelligence” (McKibben 173). “Designer Genes” is a prime example of the less feasible reasons why genetic engineering is used, for this reproductive technology focuses on the health of our future generation. McKibben clearly expresses his concern with germline genetic engineering in his essay.
(Document 2) The cultivation of plants also showed the ingenuity of the Aztecs. As described by Cortes, they built artificial floating gardens that allowed for more crop growth and easy irrigation. (Document 7) Among the crops planted was Maize or simply corn. The importance of this crop to the Aztecs was obvious as images exist of its planting dating back to as far as 8000 BCE. (Document 9) Seemingly the backbone of the Meso-american diet, corn was kept under strict watch, along with other numerous crops.
Pollan begins with an exploration of the food-production system from which the vast majority of American meals are derived. This industrial food chain is largely based on corn, whether it is eaten directly, fed to livestock, or processed into chemicals such as glucose and ethanol. Pollan discusses how the humble corn plant came to dominate the American diet through a combination of biological, cultural, and political factors. Pollan admits that he is surprised to discover that at the beginning of the food chain; almost regardless of the food being eaten was corn. Corn feeds the animals we eat, which lay the eggs we
Nevertheless, if we studied the American industry, we would find that there is one basic ingredient that seems to be in just about everything: - corn. Our food industry here in America is strongly based on corn, and as the author points out, it is used in countless forms, from being fed to livestock, to being used in processed items such as yogurt or beer. Mr. Pollan also explains just how corn came to govern the American markets and industrial food chain due to a number of factors. He also pays a visit to George Naylor’s farm in
Life Science Michael Garcia Virtual Lab #1 8/30/14 Dependent and Independent Variables Introduction The use of transgenic corn crops has increased over the years. This type of modified corn is in use because of its resistance to pests like the European Corn Borer (ECB). In this experiment, the effect of ECB infestation on corn crop yields will be examined. Two varieties of transgenic and two varieties of non-transgenic corn seeds will be used to see how well they weather the infestations. The independent variable for this lab is the ECB infestation, and the dependent variable will be the yield of corn.
Genetically engineered food will need to be judged on an individual basis. History of Genetically Modified Crops The term Genetically Modified is used to refer to crop plants created for human or animal consumption. Genetically modified foods were first seen on the market in the early 1990s. Some of these foods are usually transgenic plant products, such as : soybean, corn, canola, and cotton seed oil. Animal products were developed, but as of 2010 none are on the market.
Corn: Production, Distribution, Consumption The history of corn is focused primarily around building an agrarian society. Corn was used to build families, communities and ultimately a country. Since then, corn’s place in society has changed dramatically. Corn is no longer a small operation owned by family farms in America. The change is undeniable.
Mung Bean Experiment Lab Report I. Introduction In this experiment, mung bean seeds are being tested for growth in populated areas. Mung beans are commonly grown in East Asia and the Orient. II. Purpose and Hypothesis The purpose of this experiment is to discover mung bean plant growth habits in crowded, or no crowded areas.
Erasmus Darwin (1731-1802) was an England physician, philosopher, inventor, and poet. He published several works explaining an evolutionary view of life including The botanic garden published in two parts, Zoonomia also published in two volumes, and The temple of nature (Wade, 2002). He believed that there was a God who created the life on earth and after plants and animals developed without his intervention, growing naturally (Schultz & Schultz, 2012). He also created and anticipated many evidence for evolution that later Charles Darwin, his grandson will discuss, including animals and plant changes due to different climate or metamorphosis processes. Robert Darwin, father of Charles was the third son of his first marriage (Wade, 2002).
Genetically modified foods are boosted in nutritional value, and can be more disease-resistant, flavorful, or cheaper than natural foods. For example, plant breeders have turned the wild potato into the wide varieties that we can buy. The varieties of potatoes are different from their cousins. After years of searching scientists were able to find a way to change their genetic modification. They figured out a way to change DNA from organisms.
