In general, in which direction do convection cells in earth atmosphere move heat ariund the planet
a. clockwise along the jet streams
b. from the equator toward the poles
c. from the surface to the upper atmosphere
d. from east to west, along with the westerlies

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.
