The scale of a map is 1 cm: 17 km. find the actual distance corresponding to the map distance.
the distance on the map is 3.5 cm.

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.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
