which structure allows the action potential to travel deep into the interior of the cell to each contractile organelle?

it's unlikely a majority of a large population would agree on issues

hope this : )

the answer is c on e2020, bud.

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.
