What type of prokaryote arrangement is associated with pairs?

The arrangement of prokaryotes that is associated with pairs is referred to as diplo-. When bacteria undergo binary fission, they may divide in such a way that they remain attached to one another, forming pairs. This characteristic arrangement is typical for certain species of bacteria, such as Neisseria, which are often seen as diplococci.

In contrast, the other arrangements mentioned have distinct characteristics. Strepto- denotes a chain-like formation of cells that remain attached following division, forming long strings. Staphylo- refers to clusters or groups resembling grapes, where cells divide in multiple planes. Sarcina- describes a specific cube-like arrangement of eight or more cells, resulting from division in three planes. Each of these arrangements reflects different patterns of cell division and physical characteristics, while diplo- uniquely pertains to the formation of paired cells.
