How were the himalayan mountains formed?
a) two continental plates collide into one another.
b) an oceanic plate and a continental plate collide causing the subduction of the oceanic plate
c) an earthquake caused the eurasian plate to diverge from the indian plate, allowing the mountains to rise between
d) this mountain range is a mystery and speculation of alien activity created this range to hide their secret landing pad

the answer would be A:Two continental plates collide into one another.

Explanation:

when two plates collide to each other they form mountains. this is most likely the answer you are looking for

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

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.
