Certain parts of the brain govern specific functions. For example, the cerebellum is involved with coordination; the hippocampus with memory. Nerve cells (neurons) are the basic unit of communication in the brain.
Eukaryotic organisms use mitosis to reproduce sexually. In mitosis, the parent cell is divided into two daughter cells which be identical to the parent cell. Edit
Asexual reproduction only involves mitosis, or binary fission. This leads to clones with identical genotypes. This also results in low genetic variation within a species. â¦Sexual reproduction uses meiosis, indeed, sexual reproduction is the only function of meiosis.
