Question

Scorpions are born live, two at a time, and they immediately crawl onto the motherÍs back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves. As baby scorpions grow larger, which process occurs in their body cells?

Mitosis separates one cell into four cells.

Cells divide by mitosis.

Meiosis produces all of the new body cells.

Meiosis splits the chromosome numbers by four.

Answer 1

Ans.

As scorpions become adult, they show both mitotic and meiotic divisions as other eukaryotic organisms. Mitotic division takes place in all somatic cells of the organisms and leads to formation of two identical daughter cells from a mother cell, with same amount of genetic material as present in mother cell. Mitosis is responsible for the growth and development of organisms.

Meiotic cell division occurs in germ cells and forms four gametes daughter cells from one mother cells, having half the amount of genetic material present in mother cell.

Thus, the correct answer is 'option). cells divide by mitosis' as when baby scorpions would become larger, mitosis occurs in their body cells.
