She marks all 30 mice and releases them back into her study site. A week later she returns and traps 40 mice. Ten of the 40 mice have been marked representing mice that were captured a second time. What is her objective? To collect data for constructing a mouse survivorship curve. O To estimate the mouse population density using the quadrate method. O To determine if mice who have been previously trapped will avoid being trapped a second time. O To estimate the mouse population size using the mark and recapture method.
