Some of the benefits to Smog are: growing plants, such as corn, that are resistant to weeds and pests, larger yields of crops that create more efficient land use, better textured, flavored, and nutritional foods, longer shelf lives of foods, ND genetically modified foods create a sustainable way to feed the world (Benefits of GM Food).
There are also disadvantages to Smog that include money?making Smog is not cheap and one main goal is also to make products that last longer and sell more, gene splicing is not natural and can have adverse impacts on animals and humans that consume the product, disruption of the natural environment, insufficient government regulation, and more (Cardinal). As shown in the flowchart below, the process of splicing genes into food is a very meticulous process that can be costly and take a long time.
Materials and Methods For this lab, we used a mortar and pestle, a scale, ml centrifuge tubes, denizen water, ml microelectronic tubes, mi pipettes, and Quickstep Strip Tests. L We first used the mortar and pestle to grind our food samples down to a fine powder weighing three to five grams. The powder was then put in a ml centrifuge tube with ml of denizen water to dissolve the powder.
The mm’ pipettes were used to transfer a small amount of the dissolved sample to ml microelectronic tubes. The sample was then tested using Quickstep Strip Tests or the presence of proteins responsible for pesticide (Cry Bib) and herbicide (Roundup Ready) resistance. Results The class as a whole tested a total of twelve different foods that were corn-based. The chart on the following page shows the results of the Quickstep Strip Tests.

Both surprising and unsurprising to the class, only the three samples of sodas tested positive. It was surprising because we had expected more of the samples to test positive?especially the light corn syrup.
It was also unsurprising because there tend to be more chemicals and high-fructose corn syrup present in sodas than in other food samples. Discussion The two objectives of this experiment were to 1) understand what Smog are and how they are created and 2) assess the prevalence of Smog in the foods that we consume. My first hypothesis for the experiment was that if the Lays Original Potato Chips that I had brought contained a modified corn product, then they will test positive for pesticide or herbicide resistant proteins.
My second hypothesis was that of all the corn-based foods that the class tested, only the soda samples would test positive due to a higher concentration of corn-based ingredients. After testing all the samples, my first hypothesis was proven incorrect?at least for the herbicide and pesticide proteins we had tested for? and my second hypothesis was proven correct?the sodas were the only three ample that had tested positive for at least one of the pesticide-resistant proteins. My group had tested the Lays Original Potato Chips, the Doris Jacked, the Doris Nacho Cheese, and the Coke.
Of those samples, compared to the rest of the class, our results were the same?negative?with the exception of the Coke. The groups that had also tested a soda showed the same positive results. As previously stated, the data that I collected from the food brought to class did not support my first hypothesis because my food sample did not test positive for either test and only 25% of the samples tested showed positive results. My second hypothesis was supported by the 25% of positive results because only the three sodas had tested positive.
My overall position on GUM foods is that in some cases, GUM foods can be considered good for producing more food for malnourished and starving countries. On the other hand, when only a select few parent crops are used to create the GM crops, more precautions should be taken to preserve the parent crops in the event that the parent crop is threatened with being wiped out by pests and weeds. If no precaution is taken and the parent crop is wiped out, creating more Smog would be extremely hard, if not nearly impossible.
A policy that the U. S. Should implement for GUM foods should be that most, if not all, products that contain Smog should be labeled and products that may or may not contain Smog should also be labeled as a result of the potential health risks Smog have on both humans and animals that consume the products. Conclusion I think that this experiment was designed well for students to gain a better understanding of the basics of the process of creating genetically modified organisms.
