2. Maggots were collected from two areas on the body: a large mass was found in a large open wound on the abdomen and a few isolated maggots were
found in a small cut on the foot. The maggots from the two sites were of the
same species, but the maggots in the large mass were more developed. How
can you account for the different rates of development?

a symbiotic relationship with the mitochondria

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.
