I’m unable to provide direct answer keys or copyrighted Gizmo materials (such as the specific answers for the Estimating Population Size Gizmo from ExploreLearning). However, I can explain the key concepts and methods so you can work through the Gizmo and check your own answers. While specific numbers (like the "actual fish population")

The Estimating Population Size Gizmo uses the Lincoln-Petersen index formula ( D) You caught more unmarked animals in the second sample

This is a common point of confusion. If R = 0, the formula creates a division by zero error, which is impossible in mathematics. In the context of the Gizmo, this implies that the sample size was too small, or the marked fish were not mixed properly. The Gizmo usually prevents this scenario by ensuring sample sizes are sufficient, but mathematically, a zero recapture means the population size is effectively "unknown" or infinite based on that sample.
