Several years ago, some crop plants were genetically modified to be immune to the effects of glyphosate, a weed killer that worked well on weeds. As a result, the crop could be sprayed with glyphosate, and the weeds would be killed, but the crop would survive. From an ecological point of view, which of the following is most important to determine prior to planting the resistant crop in farm fields? A) What effect does the presence of glyphosate-resistant crops have on insect populations in adjacent fields?. B) Is it possible for the gene for resistance to glyphosate to pass from the crop plants to weeds under natural conditions?. C) Does the genetically modified crop produce yields that are better in quality and quantity than those of unmodified varieties?. D) Is the gene for resistance stable enough in the crop plant that it will be passed to the next generation when the crop plant reproduces?. Show Answer Correct Answer: B) Is it possible for the gene for resistance to glyphosate to pass from the crop plants to weeds under natural conditions?. 12. A particular plant was made using genetic engineering. What do you know about that plant? A) The genetic makeup was changed. B) It is an artificial plant. C) It cannot be eaten. D) It was developed for feeding cattle. Show Answer Correct Answer: A) The genetic makeup was changed. 13. Which career may need a know of artificial insemination techniques and equipment use? A) Nursery workers. B) Agricultural equipment operators. C) Animal breeders. D) Farm labor contractors. Show Answer Correct Answer: C) Animal breeders. 14. It is the transfer of genetic material for the purpose of treating human disease. A) Chemotherapy. B) Gene therapy. C) Gene transfer. D) Gene editing. Show Answer Correct Answer: B) Gene therapy. 15.
