A. Sponges
They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like Mesohly sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohly in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes.
The right answer is mitosis.
Mitosis refers to the chromosomal events of eukaryotic cell division. This is a nonsexual / asexual duplication (unlike meiosis).
It also refers to a very particular stage of the eukaryotic cell cycle, called the "cell cycle", which is the stage of duplication of each chromosome of the mother cell and of their equal distribution in each of the two daughter cells.
Mitosis allows the formation of two daughter cells strictly identical genetically to the mother cell.
Answer:
Speciation is the evolutionary process by which reproductively isolated biological populations evolve to become distinct species. The biologist Orator F. Cook was the first to coin the term 'speciation' for the splitting of lineages or "cladogenesis," as opposed to "anagenesis" or "phyletic evolution" occurring within lineages.
