How 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…

In conceptualizing a GMO, think of the features or characteristics that you imagine it possesses and its potential impacts on society. Answer the questions below. 1. What is your GMO, its modified characteristics and features? 2. In what ways do you think this GM0 can positively impact society? 3.

GMOs can increase pesticide resistance.arrow_forwardThe bacterium Agrobacterium infects plants and causes plant cells to develop tumorlike cellular structures and begin synthesizing sets of proteins that protect the bacterium from the plant immune response, as well as synthesize nutrients that can be used exclusively by the bacterium. Researchers testing the efficacy of two new antibiotic treatments against Agrobacterium are tasked with designing an experiment to test their effectiveness. Which of the following describes the most appropriate dependent variable in this experiment? A B с D the rate of infection the amount of treatment the number of formed tumors the rate of plant growtharrow_forwardOn the following pages, you will be asked the same question seven times: "Based on what you now know, do you think we should raise genetically modified (GM) crops?" Each time, you must answer Yes or No to that question, and each time, depending on how you responded, you will be presented with a new counterargument meant to challenge your stance. Thus, this feature presents six arguments for growing GM crops and six against, but whenever you answer yes or no, you will only see one side of the argument -- the one meant to challenge your position. However, before answering the question for the seventh and final time, you will be shown all 12 arguments for and against. At that point, you may choose Yes, No, or Undecided and then see where your vote stands vis-à-vis those of others.

Scientists genetically modify male mosquitoes in the lab. b. Mosquito offspring produced by the matings do not survive to adulthood. c. GM male mosquitoes mate with normal wild females. d. The mosquito population decreases dramatically. e. Scientists release GM male mosquitoes into the wild.arrow_forwardThese weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the farmer relies on manually removing the weeds, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the weeds but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide. Which of the following is likely the reason the weed has remained? A mutation appeared in one weed plant that made that weed not susceptible to the herbicide O The weed needed to be resistant in order to survive, so it became resistantarrow_forwardThese weeds are growing in a farmer's field.

The weed will survive long enough to reproduce. In time, the herbicide will no longer be effective on that field. The trait will spread to nearby weeds.arrow_forward
