The cell cycle is a repeating sequence of events that leads to the duplication and division of a cell. place the stages of the cell cycle in the order of their occurrence, from the earliest stage of cell growth through the latest stage of cell division.

There are two main events during the cell cycle. Interphase and mitosis/meiosis (this will depend on the type of cell)

Interphase is the part of the cell cycle where the cell is pretty much "living its life" (growing, feeding, doing metabolism).

Interphase is divided in 3 main phases.  G1-S-G2. (see attached picture)

During mitosis the cell will produce 2 new identical cells. Citocinesis is the part where the cytoplasm finally divides.

i believe it would be the lungs.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
