Question

24 multiple choice 2 points what would most likely make a mark-recapture study invalid? sampling on two consecutive days a large population size individuals avoiding recapture after being marked using bright non-toxic markers

Explanation:

Mark - Recapture method assumes that marked individuals mix randomly in the population and have the same probability of being recaptured as unmarked ones. If individuals avoid recapture after being marked, it violates this assumption. Sampling on two consecutive days is common in some studies. A large population size is not a problem as the method can still be applied. Using bright non - toxic markers is a proper practice.

Answer:

Individuals avoiding recapture after being marked.
