Biofuel is an experimental resource created through the use of living matter. it is a plant-based fuel and a renewable resource that can be used as a substitute to traditional fuel. a research team has recently discovered a “switch” that affects cell growth of a red algae used in the production of biofuel. through the inactivation of this switch researchers observed a drastic increase in the production of red algae. if researchers are able to successfully recreate the effects of this mechanism, a wide range of industries will be interested in the purchase of this research. what should the research team take into consideration when analyzing the negative environmental effects of their findings? a loss in biodiversity due to the replanting of the same modified crops each year the decrease in the use of nonrenewable resources like gasoline that will occur as a result an increase of payment coming from interested industries that they can be used to fund future research the increase in bioplastics, also made from algae, that can phase out single-use plastics like plastic shopping bags

Our planet has experienced five major extinctions in the four billion year history of life. the first, 450 million years ago, occurred shortly after the evolution of the first land-based plants and 100 million years after the cambrian explosion. the second extinction occurred 350 million years ago, causing the formation of coal forests. next earth experienced two mass extinctions during the triassic period, between 250 and 200 million years ago. the fifth mass extinction occurred 65 million years ago, ending the reptilian dominance of the earth. according to richard leakey, the sixth mass extinction is happening right now. leakey suggests that we, the human race, are the cause. each year, at our hand, approximately 50,000 species vanish from earth. he believes that man is destroying earth at a rate comparable with the impact of a giant asteroid. leakey's statistics indicate that 50% of earth's species will become extinct within the next 100 years assuming leakey's hypothesis of a sixth mass extinction to be true, how will we expect the model to change? a) a sharp spike in the graph approximately 100 million years from now b) a dip in the graph, followed by a sharp spike about 100 million years from now c) a sharp spike in the graph immediately following the "0" location of the x axis d) a plateau following the "0" mark on the x axis, followed by a gradual rise to a new peak
