Fill in the blanks • The chemical energy from the cell is used to___ the shape of the protein to allow for the particle to be moved to the other side of the membrane of the cell.
• The protein is then
to its original shape.

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.
