Stephanie growing five bean seedlings in a lighted area and five bean seedlings in a dark area is the best experimental procedure if she wants to do an investigation about the effect of light on the growth of bean seedlings.

your answer should be c) enjoy!

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.
