Amphipods were tested to determine their ability to survive in different concentrations of Cd, either 100 ug/L for the FO (just collected population) or 20 ug/L for the F1 generation. The median time in hours (LT50) until death was reported as the endpoint. a. The Ardi population was suspected to be resistant to metals. In the FO generation, do the results support that this population has increased tolerance to Cd? Do the results in the FO generation support that this population is resistant to Cd? b. Describe the difference between the tolerance across all populations in the FO (exposed to 100 ug/L Cd) vs. the tolerance of the F1 generation (exposed to 20 ug/L)? Do these results support that the Ardi population is resistant to Cd?
