- Genetically modified foods (GMO's) provide farmers with increased crop yields, reduced spoilage and increased pesticide resistance, however, a common concern of GMO's is O A. invasive species O B. unknown longterm side effects O C. herbicide resistance O D. vitamin fortified foodsWhich of the following statements about organic farming is not correct a. Crops are planted close together within each bed, to prevent space for weeds to emerge b. Biopesticides like Bacillus thuringiensis are not used as it can harm the crop C. Uses only naturally produced inputs like compost, manure d. Does not use pesticides e. Natural enemies of the pests are used to control the population of pests Pick which one of the following is Incorrect about the Greenhouse effect. a. Life on the earth is possible due to greenhouse effect b. Increased emission of greenhouse gases is a natural process С. Greenhouse effect is a natural process that maintains earth's temperature d. More is the emission of greenhouse gases, more is the temperature of the earth's atmosphere e. CO2 emission for last few decades is really worrisome utrients entered an estuary?Which of the following is true about raised bed agriculture (like the Waru Waru)? OA. It allows crops to be grown during floods OB. It allows crops to be grown during droughts OC. It promotes monocultures OD. A and B O E. A, B, and C
- The increased reliance on genetically engineered crops grew from the need to ____. a. produce more food at lower cost without harming the environment b. develop new species of crop plants c. provide farmers with more expensive seeds d. find more ways to profit from crop plants e. find new pesticidesOpponents of the widespread use of synthetic pesticides contend that the harmful effects often outweigh the benefits. Which of the following is not a harmful effect cited by opponents? O threaten human health O harm to wildlife O put farmers on financial treadmill O threaten crop monocultures O foster genetic resistance(10)Sustainable agriculture consists of farming and grazing that maintain the healthy soil, clean water, pollinators, genetic diversity, and other resources needed for the production of crops and livestock over the long term. Strategies undertaken toward this end include all of the following EXCEPT: Increased use of new fertilizers without waiting years to test their viability moving back toward the more traditional model of agriculture genetic engineering of crops and livestock Reduction of fossil fuel inputs
- Some varieties of soybeans have been genetically modified. They have been changed so that they do not die when a particular herbicide is sprayed on a field. How would this genetic modification improve the soybean crop? It would enable the crop plants to kill nearby weeds directly. It would protect the crop when farmers sprayed for harmful insects. It would allow farmers to eliminate weeds that compete with the crop. It would increase the fitness of the crop plants and improve their growth.Corn undergoes C4 photosynthesis and does not fix nitrogen, whereas Alfalfa is a nitrogen-fixing plant that utilizes C3 photosynthesis. Both species are equally watered. What can you interpret from this dN/dt vs. N plot given the biculture and monoculture treatments for each species (alfalfa & corn)? Biculture: Both corn & alfalfa grown together in the same pot Monoculture: Corn & alfalfa grown in separate potsGeographer, historian, and author Jared Diamond (1987) once referred to agriculture as "the worst mistake in the history of the human race." Given what you have learned about the health consequences of the domestication of plants and animals for humans, how would you respond to his statement?

- Which of the following is the best example of coevolution?O A. Antibiotic-resistant strains of bacteria proliferate when antibiotics kill good bacteria and select for any cells resistant to that antibiotic.O B. Birds and bats both have wings, but these structures developed independently.O C. Sharks and dolphins look very similar, but sharks are a type of fish, and dolphins are a type of mammal.O D. Some plants that require pollination have developed ways to attract pollinators, such as brightly colored and fragrant flowers; pollinators have developed specializedstructures to obtain pollen and nectar from the plants.The purpose of making observations is to lead someone to ask a question about how or why or when something occurs in the natural world. This, in turn, stimulates the formation of possible explanations, termed hypotheses, that can be tested by collecting data from a study or an experiment. Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. A group of scientists is conducting a study on the benefits of organic farming. What should be the final product of the observational stage of their study?Which of the following is true of India? The dramatic decrease in the number of rice varieties planted puts the food supply at risk. O Use of pesticides have remained stable over the past century. There has been an increase in the diversity of corn crops due to deliberate efforts. Antibiotic resistance is unlikely to be a problem. The effects of climate change are unlikely to have strong effects on agriculture.
