Chapter 30, Problem 11TYU
SCIENTIFIC INQUIRY
Critics of GM foods have argued that foreign genes may disturb normal cellular functioning, causing unexpected and potentially harmful substances to appear inside cells. Toxic intermediary substances that normally occur in very small amounts may arise in larger amounts, or new substances may appear. The disruption may also lead to loss of substances that help maintain normal

In 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?
Genetic engineering is a process causes the production of GMOs ( Genetically Modified Organisms) due to the ideas of biologists. The presence of the products contributes the division of the society in relation to GMOs effects.
TASK:
You serve as a genetic engineer, if you are given a chance what GMO would you like to produce?
What to do:
Give a name of your GMO
Illustrate and/or describe your GMO
List all the possible pros and cons
Unlike genetically modified organisms (GMOs), synthetic organic substances have not met too much opposition, although the production of both require human intervention and manipulation of natural substances. Why do you think the synthesizing of organic substances is readily accepted by society in general whereas the mention of GMOs immediately raises
concerns?

- Read this paragraph from a passage. However, not everyone is convinced that genetically modified foods are beneficial. Opponents say that too little research has been done on the effects of GMOs on humans and on the environment. They argue that GMOs could be creating new poisons. They are also concerned about what might happen if genetically modified plants breed with wild plants. Some farmers are concerned about the possibility of inadvertently crossbreeding GMO plants with non-GMO plants. For example, if the pollen from a GMO plant blows into their organic field, now that organic crop could become a GMO crop. The possibility also exists that all this interbreeding could lead to new strains of herbicide-resistant super-weeds. What is the topic sentence of this paragraph?arrow_forwardgenetic engineering involves altering the genetic make-up of an organism to produce products with new traits than it was originally. Name two advantages and three disadvantages of genetically modified foods with examples.arrow_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_forward
