Immune system cells enter a resting phase after undergoing mitosis. when activated by an infection for example, they can reenter the sequence of events in the cell cycle that leads to cell division. the correct sequence would be (put in order: g, g2, m, s )

G, S, G2, M

Explanation:

Cell cycle refers to the orderly events that prepare the cells for cell division and finally divide the parent cells into the daughter cells. The cell cycle consists of two stages: interphase and M phase.  

Interphase is the phase wherein cells prepare to enter the M phase. Interphase has three stages: G1, S, and G2.

G1 is the first gap between represents the time between the end of mitosis and the beginning of the S phase. During the G1 phase, normal growth and metabolism take place. G1 phase is followed by the S phase, the synthesis phase, during which DNA replication and synthesis of histone proteins occur.  

The cells then enter the G2 or the second gap during which cells synthesize more proteins and prepare to enter the M phase.  

M phase is the phase of nuclear division that divides the nucleus of the parent cell into 2 or 4 daughter nuclei (depending on the type of the cell division that the parent cell has entered).

Therefore, the sequence of the stages that the cell will go through is G, S, G2, and M.  

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
