Choose all the answers that apply. Organisms within the same species
have similar morphology
can breed and create fertile offspring
have similar physical characteristics
can breed and create sterile offspring
have similar behaviors

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.
