Which organelles work together in converting the potential energy of organic compounds into a suitable form for media used by the cell ?

a, ribosomes and mitochondria
b, nuclear and chloroplast
c, liposome and vacuole
d, mitochondria and chloroplasts

A, after all the mitochondria is the powerhouse of the cell

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.
