Does reptiles and insects come under all the animals?

For reptiles "They are cold-blooded animals belonging to the phylum Chordata of Animal kingdom"

Explanation:

Insects "Insects are also animals, but they then diverge from humans and are classified as arthropods (which means jointed legs) and then hexapods (which means six legs)."

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.
