What are two ways to identify NESW?

-The sun

-shadow

Explanation:

-The sun rises in the general direction of east and sets in the general direction of west every day, so you can use the location of sunrise or sunset to get an approximate idea of direction.

-The shadow will always move - or, more precisely 'grow' in the west-to-east direction. (Before noon, when the sun is rising, the shadow will grow shorter and after noon when the sun is setting, the shadow will grow longer)

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

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).
