Prophase is the first phase is when the two sister chromatids pair up and the nucleoli disappears. Prometaphase is the second phase where the microtubules begin to separate from each other, each pair of microtubules attach to the kinetochores and some nonkinetohore microtubules interact with those from the opposite pole of the spindle. Metaphase is the third phase where the chromosomes are lined up on the invisible line of the metaphase plate. Anaphase is the fourth phase where the two daughter chromosomes begin to separate from each other to opposite poles. Telophase is the last phase where the two daughter nuclei form creating two identical nuclei.

Answer from: chloesmolinski0909

Mitosis is a type of cell division which produces two genetically similar daughter cells. This is involved in the cells of growth of somatic cells in an organism which has to to be produced with the same genetic material. It is also involved in the asexual mode of reproduction as it produces clones with the same genetic material such as in angiosperms.

Mitosis is divided into two phases- karyokinesis and cytokinesis where karyokinesis is divided into 4 stages which can be easily marked as:

Prophase- chromatin condensation, nuclear envelope disappears. Prometaphase- chromatin condenses to form a packaged structure called chromosomes. Metaphase- chromosomes align at the equatorial plate of the cell, chromosomes highly condensed. Anaphase- chromosomes start separating, each chromatid moves towards the opposite pole of the cell. Telophase - cytokinesis begins, nuclear envelope reappears. Cytokinesis- cell division by the appearance of cell furrow in animal cells and cell plate in plant cells.

Answer from: Quest

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
