Problem 2: Leopard Frogs. A biologist nets 40 leopard frogs from a local pond, tags them with a microchip, and releases them unharmed. A week later, she nets 65 frogs from the same pond, including 26 with tags. Based on the Lincoln−Peterson index, estimate the number of leopard frogs in the pond.

good lesson

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
