Which one of the following is NOT a way that humansincreased the carrying capacity of agricultural land during the'green revolution.' Question 1 options: Increased use of irrigation to supply water. Adding inorganic fertilizer to the land to supply limitednutrients. Use of pesticides to control natural predators of crops. Increasing the genetic diversity of crop plants to help themwithstand environmental change. This approach to determining safety minimizes thechances of releasing a dangerous product but may inhibit innovationand advancement of technology. Question 2 options: Absolute safety approach Innocent until proven guilty approach Precautionary principle Artificial selection Which of the following statements apply to BOTH geneticengineering and artificial selection of agricultural plants? ChooseALL that apply. Question 3 options: Has allowed humans to increase the yield that can be produced ina given area of cropland. Has introduced genetic sequences into crop DNA that did notarise through random mutations. Has contributed to the lack of genetic variety in the world'sagricultural crops. Interbreeding of crops produced in this manner with wildrelatives can reduce the biodiversity of those wildpopulations. Which one of the following is the best explanation ofhow insects can become resistant to a pesticide? Question 4 options: When humans use pesticides, it causes mutations in teh genes ofthe insects that allow them to survive the pesticide. If we use thepesticide a lot, pretty soon all of the insects will develop thatmutation. A very small number of insects in a population have a mutationthat makes them less susceptible to the pesticide. When we use thepesticide a lot, we kill off the majority of insects that don'thave the mutation and the only insects that survive and breed arethose with the mutation that makes them resistant. Insects exposed to a pesticide would, over time, buildresistance to the pesticide. If two of these insects mate together,their offspring would be even more resistant to thepesticide. Which one of the following is NOT a consequence of thepractice of tilling? Question 5 options: Increases rate of erosion of topsoil Changes interactions within the ecosystem of soilmicroorganisms Removes unwanted plants to reduce competition for nutrients. Increases the amount of organic matter and nutrients present inthe soil
