Which microscope would be most useful for examining the contours of the surface of a bacteria cell? . a)compound light microscope. b)binocular stereomicroscope. c)scanning electron microscope. d)transmission electron microscope.

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.
