A research group discovered a new enzyme happyase that catalyzes chemical reaction
Sad_student <-> Happy_student

Researchers characterized this enzyme and found that at [Etotal]=10nM, this enzyme has a Vmax at 2.5 microM/s. it was also experimentally measured that at [Sad_student]=0.05 mM this enzyme has V0=500 nM/s. what are the kcat and Km of the happyase enzyme?

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.
