When are cells triggered to go through mitosis

So far, we have discussed the phases of the cell cycle and the controls that regulate the passage of the cell from one phase to the other. Once the cell has successfully completed S-phase, when its chromosomes are duplicated, and passed through G2, it is ready to enter M-phase, when mitosis occurs.

1. is geographic distribution

2 is increasing complexity

3 is transitional forms

i think it is d. objects resist changes in their state of motion.
