What is the other name for the planetary accretion model?

a. fractal assembly
b. molecular accretion
c. planetesimal assembly
d. solar nebular disk

The correct answer is option C, Planetesimal assembly

Accretion is the assembling of particle to form a massive object by virtue of gravitational attraction. Most of the celestial objects are formed by the accretion process. Planetesimals is an important step in the formation process of planet which involves the accumulation of dust and ice particles. Thus Planetary assembly work on the same principal of planetary accretion model and hence it can be stated as another name of planetary accretion model

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).
