Andrea wants to understand the impact of the fragmentation of habitats on wildlife species. Which method will help Andrea with her study?

Andrea will study how many species in the area have gone extinct or endangered.

Explanation:

Organs can be kept alive only when placed into a culture solution, this can increase the life of the organs by few weeks. Cultured organs can be kept alive for several weeks before transplant.

Explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
