4. for your organ system, describe how the system works at the tissue level?

5. describe what would happen if an organ in your specfic organ system stopped working?

thinking it would be physical characteristics

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.
