Question

read the passage to answer the question.
even though scorpions are related to spiders, there are many differences between the two organisms. one difference is that scorpion young do not hatch from eggs as spiders do. scorpions are born live, two at a time, and they immediately crawl onto the mother’s back for protection and care. they remain there for two weeks as they grow big enough to take care of themselves.
as baby scorpions grow larger, which process occurs in their body (somatic) cells?

• mitosis splits the chromosome numbers by four.
• one cell splits into 3 cells in meiosis.
• cell nuclei are copied during mitosis.
• meiosis produces cells that combine to form a larger cell.

Explanation:

• Mitosis is the process by which somatic (body) cells divide. In mitosis, the cell nucleus is copied, and one cell divides into two daughter cells with the same number of chromosomes as the parent cell. This is crucial for growth, repair, and asexual reproduction.
• Meiosis is a different process that occurs in reproductive cells (gametes) and results in cells with half the number of chromosomes. It is involved in sexual reproduction.
• The first option about mitosis splitting chromosome numbers by four is incorrect. Mitosis maintains the chromosome number.
• The second option about one cell splitting into three in meiosis is wrong. Meiosis typically results in four daughter cells (in the case of gamete formation in many organisms).
• The fourth option about meiosis producing cells that combine to form a larger cell is incorrect. Meiosis produces gametes (sperm and egg in animals) that combine during fertilization, but it's not about forming a larger cell from the products of meiosis directly in the context of somatic cell growth.

Answer:

Cell nuclei are copied during mitosis.
