Cheilostome bryozoans have a complex life cycle with distinct asexual and sexual modes of reproduction (Taylor, 2020; McKinney and Jackson, 1991). Asexual reproduction allows for a single colony to grow larger by increasing the number of zooids in the colony. The sexual stage of the cheilostome bryozoan life cycle leads to the …The taccretion theory (or accretion) in astrophysics, explains that planets and other celestial bodies are formed by the condensation of small dust particles, attracted by the force of gravity.
