Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.

You are giving your hypothesis.
Answer:
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.
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
