Yes, mitosis does indeed stop. There is a limited amount of times that cells can divide. For example, muscle and nerve cells. In fact, nerve cells stop at about the time we are born.

<span>Flatworms possess excretory organs known as nephridia. Specifically as annelids, flatworms possess a variant known as metanephridia. This variant is defined by a cilia-lined funnel that opens into a coelom that empties through a anus to the outside of the organism.</span>
Water goes downhill and the earth isn't Very spherical so it'll have ways for the water to go down and up to distribute the water around the world.
Answer:
Homologous chromosomes are separated from each other.
Explanation:
In meiosis I during metaphase, all the homologous chromosomes of the cell pair up and get arranged near equatorial plate. Subsequently after completion of meiosis I, these homologous chromosomes get separated from each other so that out of the two cells which are produced after meiosis I could get one chromosome each from the homologous pair. During anaphase I of meiosis I, spindle fibres are formed which drag each of these homologous chromosomes towards two opposite poles. Soon after that, cytokinesis occurs during telophase I of meiosis I leading to the generation of two cells.
For example, humans have 46 chromosomes or 23 pairs of homologous chromosomes. After completion of meiosis I, two cells are produced and each one of them has 23 chromosomes.
