Final answer:
The positive effects of GMOs mentioned in the article include increased shelf-life of vegetables, soybeans producing more protein and vitamins, and increased resistance of crops to environmental stresses.
Step-by-step explanation:
The positive effects of GMOs mentioned in the article include:
GMO varieties of vegetables last longer: Genetic engineering has helped create plants with better shelf-life, allowing them to stay fresh for a longer time.
Soybeans produce more protein and vitamins: GMO soybeans have been modified to produce higher levels of protein and vitamins.
Increased resistance of crops to environmental stresses: Genetic engineering has enabled the creation of transgenic crops that withstand environmental stresses, such as drought and salty soil.
