What is one of the main functions of lipids

The lipids perform three primary biological functions within the body: they serve as structural components pf cell membranes, function as energy storehouses, and function as important signaling molecules.

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.
