For over a decade, farmers in the u.s. have been planting genetically modified crops. an example of one of these crops is corn that is resistant to weed-killer. this makes it so that no corn is lost due to contact with herbicide meant to kill weeds. while this is seen by many as a positive development, others see it as a cause for concern. what is one possible specific negative side effect of planting corn that is resistant to weed-killer? a) genetically modified corn, as well as other plants, is unnatural. b) corn will replace wheat and other crops as our main source of carbohydrates. c) plants with modified genomes may have an unforeseen impact on the environment. d) the resistance gene could be transferred to actual weeds, making farming more difficult.

Answers ! scientists have genetically engineered crops to be resistant to herbicides. this allows farmers to kill weeds with small doses of herbicides that don’t harm the crops. why, then, are people concerned that transgenic plants may lead to an increase in the use of herbicides? cross-pollination could cause the crops to lose their herbicide resistance. weeds may naturally develop herbicide resistance with each dose. herbicide-resistant crops may grow out of control and become weeds. cross-pollination could pass herbicide-resistant genes to the weeds.
