Answer:
Two domains: Archaea and Bacteria
Explanation:
There are three domains of life namely Archaea, Bacteria, and Eukarya. Both Archaea and Bacteria contains organisms that reproduce asexually, i.e. binary or multiple fission, fragmentation, or budding. By these means, organisms divides its cells to more than one cells containing splited genetic materia. The dividing cells then can survive independently.
When the upper water layers warm in the summer months, they become separated from deep water by a transition zone known as a thermocline. In a thermocline, the temperature decreases rapidly with small increases in depth. This phenomenon linking temperature change with depth is called temperature stratification.
If you mean periodic table then it would be atomic number
