Many concerns have been raised about the safety of GMOs. These are all concerns that have been raised EXCEPT
A. Genes that offer herbicide resistance will be passed on to weedy species making "superweeds".
b. GM crops will cross with non-GM crops and move the recombinant genes into crops where farmers don't want them.
c. Genes added to crop plants can negatively affect the health of people who eat the crops.
d. Genetically modified crops increase the use of fossil fuels and therefore increase the production of carbon dioxide.
A. What is the % of GMO corn, sugar beets and soybean grown in the US?
B. . Differentiate between GMOs and Genetically Engineered (aka Transgenics) Organisms?
C. Brassica oleracea is the wild parent of what types of agricultural crops?
D. What are RoundUp Ready (RR) crops?
GMOs can be used to create an increased crop rate at a lower price and therefore can be used to solve the problem of world hunger. Introducing GMOs to third world countries can conserve labor, resources, and land. Nutritional value and vaccines added to the crops can improve life in the countries. These proven benefits outweigh the fact that allergies and effects on wild plants are only potential.

- Food plants or crops, which have been genetically altered, are known as genetically modified foods. The genetic alteration is meant to make it commercially competitive, yet it is not without environmental and ethical concerns and dilemmas. What according to you are the Four main short term benefits to the producer/consumer of genetically modified food crop, elaborate? Also identify and explain any Four long term negative impact of genetically modified food crop on the environment as well as human health.arrow_forwardIn October 2002, the government of the African nation of Zambia announced that it was refusing to distribute 15,000 tons of corn donated by the United States, enough corn to feed 2.5 million Zambians for three weeks. The government rejected the corn because it was likely to contain genetically modified kernels. The government made the decision after its scientific advisers concluded that the studies of the health risks posed by GM crops “are inconclusive.” Do you agree with Zambia’s decision to turn away the corn? Why or why not? In your answer, consider that at the time, Zambia was facing food shortages, and 35,000 Zambians were expected to starve to death over the next six months. How do the risks posed by GM crops compare to the risk of starvation?arrow_forwardGenetically modifying seeds to produce herbicide-resistant plants that increase crop yields has revolutionized modern agriculture. However, genetically modified organisms (GMOs) have come under fire in recent years, with consumer groups calling for mandatory GMO labeling on all food packages that contain GMO ingredients. GMO labeling laws have been in force in the European Union and other countries for several years, but the threat to the U.S. food industry is only now surfacing. Although bills requiring GMO labeling have been introduced in many state legislatures, Vermont is the only state where such a law has so far withstood the first round of legal battles from the industry. Leading chemical companies, including Monsanto, BASF, and DuPont, are the world’s largest suppliers of seeds that grow the food that feeds the world. To counter the GMO labeling threat, they now are turning to mutagenesis as an alternative technique to create herbicide-resistant crops. Mutagenesis mimics the…arrow_forward
- Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forwardMuch of the controversy over genetically engineered foods has centered on whether special labeling should be required on all products made from genetically modified crops. Some people have advocated labeling that identifies the product as having been made from genetically modified plants. Others have argued that food labeling should be required to identify only the ingredients, not the process by which they were produced. Choose a side in this issue and justify your stand.arrow_forwardExplain two advantages of GMO plants over traditional plant breeding.

- The use of microorganisms to decrease pollutants in the environment is most accurately referred to as: A.-transgenics B.-bioremediation C.-bacteriomics D.-phytoremediation E.-genetic engineeringarrow_forwardBT corn is toxic only when eaten by plant pests like European corn borer/Lepidopteran larvae which is not evident to have a toxic effect when consumed by humans. Based from the statement, what do you think is one of the properties of GMO (Genetically Modified Organism)? a.Genetic engineering provides quality organisms for practical use. b. GMOs provide an enhanced nutrient-based content for consumers like herbivores., c.Transgenic organisms are always harmful when consumed by humans. d. The toxicity of some GMOs is selective only to certain type of organisms.arrow_forwardHow are we going to feed and clothe the rapidly rising human population worldwide? How are we going to stop famine and crop loss? These are some very important questions biologists are working on as the world changes and problems arise. One possible solution could be the increased use of technology to improve food crops. These crops often have foreign DNA inserted into them that produces a protein product, such as herbicide resistance, to protect the plant or increase yield. They are termed GMO's (Genetically Modified Organisms) and they are hotly debated in both science and the public sphere. In this discussion you will demonstrate an understanding of GMOs and reflect on the pros and cons of their development and use This week's discussion involves 1 part. In this discussion, pick a side, PRO or CON, and argue your case that GMO's are either going to save the world or destroy it. You may very well find that this issue is not as black and white as it is made out to be! Please remember…arrow_forward

Which among the scenarios below are the benefits of using GMOs? I. Genetic engineering in food can be used to alter genes in crops leading to new diseases in pants. II. Genetic engineering in crops such as rice, corn and tomato can be used to obtain new strains with better nutritional qualities. III. Genetic engineering in food can be used to create totally the same substances such as proteins and other food nutrients. IV. Genetic engineering can be used to increase the immunity to diseases in plants leading to uncontrolled transfer of the resistance genes to the harmful pathogens. V. Genetic engineering can restrict the diversity in organisms. VI. Genetic engineering can be used to suppress negative traits in human like certain genetic diseases. a. II, III, IV and VI b.
