1. Plant breeders wanted to produce a better variety of tomato by selective breeding. Two plants‚ of the varieties Tangella and Piranto‚ were crossed. (a) Some flowers of each variety were covered with cellophane bags. The diagram shows a covered flower and a brush. (i) Explain why some flowers were covered with cellophane bags during the selective breeding. .......................................................................................................................... ........

According to the WHO‚ Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally‚ e.g. through the introduction of a gene from a different organism…. Most existing genetically modified crops have been developed to improve yield‚ through the introduction of resistance to plant diseases or of increased tolerance of herbicides. The WHO also adds that‚ GM could be used in changing the level of nutrients in food

what a genetically modified organism (GMO)‚ a GMO is known as an organism that has been genetically modified this genetic material has been reformed to improve product quality. GMOs are used for many things although the best-known use is for genetically modified foods. According to the World Health Organization “Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally‚ e.g. through the introduction of a gene

It’s been said that humans are what they eat. The relationship humans have with food is unappreciated. Food is the fuel that keeps humans going‚ gives them the energy needed to be creative and productive; it is the building block of society‚ after all‚ it wasn’t until the Neolithic Era‚ when humans figured out a way to domesticate plants and animals‚ that any form of organized society formed. Even during the previous hunter-gatherer foraging era‚ humans were very connected to the food they ate; understanding

risks. Food labeling is also important because it informs consumers about the certain ingredients in processed foods that some people are allergic to. Labeling foods that have been modified trough genetic engineering let’s people know that their food has been genetically altered. Genetic Engineering involves the embedding of different strains of DNA and the bringing together of a variety of bacteria and unnatural chemicals. There is still a lot of unknown risks about the effects of consuming food

modified food or GM food product is defined as “meat and edible plants modified through genetic engineering” (Genetically Modified (GM) Foods‚ 2015). Furthermore‚ human beings have engaged in the process of genetically modifying plants and animals‚ with selective breeding practices within identical species‚ “since the beginning of civilization” (Genetically Modified (GM) Foods‚ 2015). However‚ current methods of genetic modification can cross species boundaries‚ which require suppressive techniques to

Frankenfoods: It’s What’s in the Inside that Counts During the Neolithic Revolution‚ human life revolutionized. Humans started living in cities‚ forming class hierarchies‚ and organizing labor. However‚ the most significant turn of the new era was the advent of agriculture. Agriculture made the Neolithic Revolution truly a “revolution” by removing the need for humans to move from place to place in search for a meal and giving humans the ability to feed not only their families‚ but their friends

Currently in the US‚ only about 36% percent of the US Population could name the three branches of government‚ meaning that the US population doesn’t fully understand what our government does and what it is made out of that could affect choices that could happen in the future. It has many comparison and similarities as in The Giver. Overpopulation is a growing problem that must be solved in a correct way‚ but there are rights that are to be followed.

This exactly what we see in the film in the way of Genetic Enhancement. However‚ throughout the film we are faced with the question ‘How much is too much?’ As a result of tampering with Mother Nature it has led to Gattaca being

whose characteristics have been altered using the techniques of genetic engineering. (Add Citation). The general principle of genetically modified organisms is to alter genetics on an organism’s genome. This is done by adding‚ deleting or mutating genetic material.(Add Citation). Adding DNA to an organism results in recombinant DNA. Recombinant DNA aresequences that result from the use of laboratory methods to bring together genetic material from other organisms‚ creating sequences that would not
