These are the brain, heart, kidneys, liver, and lungs. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones.
For the beetle genus, see Coprini. Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis.
What phase of mitosis do chromosomes become visible? It's generally agreed upon that chromosomes become visible during prophase of the cell cycle. Some scientists will say prometaphase (sort of a bridge between prophase and meta â¦ phase). Mitosis would occur after telophase of the cell cycle (Prophase, Metephase, Anaohase, Telophase).
