What are the reasons for a biased sample

☐ 17. (07.08 MC) The prairie chicken was once widely seen in many areas across the Great Plains.

They require tall grass prairies as their habitat. Which of the following is the best explanation for their endangered state? (4 points) The prairie chickens lack genetic diversity and resilience to changes in environment, resulting decline of the population. Environmental perturbations increased the rate of adaptive alleles. The prairie chickens have adapted to many new environments. The prairie chickens are genetically diverse and resilient to environmental perturbations.
