Whether the data supports the hypothesis that bluefin tuna transported radioisotopes from Fukushima in their body. Concept introduction: Bioaccumulation is the concentration of a pollutant inside an organism’s tissues causing the amount of the pollutants to increase over time. Trophic level also affects the pollutant concentration by the process of biological magnification. The concentration of the chemical increases in the ecosystem as the pollutants move up the food chain. Bioaccumulation and biological magnification even in low concentration of the pollutant (depending on toxic potential) can have detrimental effects on a species.

Every day, Sulfur surface coverage doubles in a pond On Day 30, the surface of the pond is completly covered. What was the first day that greater than 30% of the pond was covered?

A polluted lake contains 3 x 10' toxic Poisonum nasticum cells per milliliter. Assuming these grew logarithmically with a doubling time of 10 hr from an initial group of cells introduced to the lake, choose the equation that would calculate how many cells per milliliter were originally introduced into the lake 50 hr ago (N¡). N; = (3 x 107) / 25 cells N¡ = (3 x 107) × 210 cells Nj = (3 x 107) × 25 cells N¡ = (3 x 107) / 210 cells O None of the above are correct
