Inquiry and Analysis: Are Microplastics Being Consumed by Ocean Animals? Skip to question Review the Inquiry and Analysis feature "Are Microplastics Being Consumed by Ocean Animals?" and answer the following questions. A graph plots exposure time in hours against the degree of particle uptake.The horizontal x-axis represents exposure time in hours; its scale reads 3, 12, 24, 48, and 96. The vertical y-axis represents the degree of particle uptake, ranging from 0.0 to 2.5 in increments of 0.5. The data points plotted in the graph are as follows: The first sets of points represented by triangles are (3, 0.25), (6, 0.0), (12, 0.0), (24, 0.25), (48, 0.0), and (96, 0.0), and a dotted line declines through these points. A second set of points represented by dotted circles are (3, 1.0), (6, 1.25), (12, 2.0), (24, 1.45), (48, 1.49), and (96, 1.75). A dotted line rises close to these points. All the values are approximate. Time for 50% accumulation of microplastics For the tanks with added microplastics (green line), at what point have the animals accumulated about 50% of the total degree of microplastic uptake? Multiple Choice 6 hours 3 hours 24 hours 12 hours
