APES Unit 8 Progress Check, MCQ Part B Based on the data in the graph, which of the following solutions most likely led to the decrease in the amount of waste sent to landfills from 1990 to 2015 ? - answer D) Increased recycling of waste Based on the data in the graph, which of the following likely occurred from 1960 to 2015 because of changes in solid waste disposal methods? - answer A) Fewer natural resources needed to be extracted.One benefit of solid waste disposal in landfills is that the methane produced from decomposition can be harnessed for energy. Based on the data in the graph, methane production from waste management most likely peaked during which of the following years? - answer B) 1990 At what step in the diagram would the last solid waste be removed from the wastewater in the treatment plant? - answer C) C At what step in the diagram would wastewater most likely be treated with chlorine or UV light to remove bacteria? - answer D) During step D Based on the diagram, organic solids that have settled to the bottom of the treatment tanks in step B are transferred to which of the following for further processing? - answer

The table below shows the number of brine shrimp that hatched over 72 hours in three different concentrations of salt water. All tanks had 50 eggs at the start of the study.Which of the following claims about brine shrimp is best supported by the data in the table? - answer D) The optimal salinity for brine shrimp hatching is 30mg/100mL Based on the data in the table, which of the following concentrations of sodium chloride is most toxic to brine shrimp? - answer A) 0mg/100mL A scientist wanted to investigate the effect of tropospheric ozone on the respiratory function of mice. Twenty female mice were placed in one of five different field environments that mimicked the natural habitats of the mice. Each environment had a tube connected to it that would pump in a set level of ozone measured in ppm. In each
