Answer:
Alpha Centauri and the Sun.
Answer:
a. gluteus maximus
Explanation:
The gluteus maximus muscle belongs to the most superficial layer of the dorsal gluteus musculature, being a thick and quadrilateral mass that forms the buttock prominence. Its upper edge is thin and covers the gluteus medius muscle, while its lower edge is prominent and free, moving inferolaterally and being crossed by a horizontal gluteal fold.
This is the muscle used for dorsagluteal injections.
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).
