Recently it has been proposed that three domains be added to our hierarchy of classification of living things . when these three domains are added, where do they fit in the hierarchy.

i think its white blood cells

i hope this

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.
