उत्तर
Yes, a snowball indeed gains mass, volume, and size; when it is rolled over. But in this case, the increase in the size of the ball is due to the accumulation of material from outside. In the case of growth in a living being, the growth happens because When the cell cycle is completed in the cell, i.e. meiosis and mitotic divisions leading to the generation of new protoplasm and nuclear mass, material accumulates inside the cells of organisms. As a result, the growth of a snowball differs from the growth of a live organism.
