Aplant’s cotyledons a. are the fleshy part of the fruit that contain the seeds and endosperm. b. the seeds to be dispersed by animals or by the wind. c. play a role in regulating the length of the plant’s period of dormancy. d. store nutrients and transfers them to the embryo during germination.

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.
