In most animal life cycles, the multicellular diploid stage is the dominant ploidy.
The multicellular diploid stage is the most obvious life stage in the diploid-dominant life cycle, as it is in most animals, including humans. Almost all animals follow a diploid-dominant life cycle strategy in which the organism's only haploid cells are gametes. Almost all animals have a diploid-dominant life cycle, with the gametes being the only haploid cells. The gonads produce special diploid cells known as germ cells early in the development of an animal embryo. During the sporophyte phase, a diploid (two-chromosome) plant body grows and eventually produces spores via meiosis.

Answer:
Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. Obsidian is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth. ... The inhibition of atomic diffusion through this highly viscous lava explains the lack of crystal growth.
