Upon what two factors does the magnitude of the gravitational force between two objects depend

Mass and distance are the two factors which depend on the magnitude of the gravitational force between two objects.

Explanation:

There is a direct relationship present between mass and gravitational force while inverse relationship between distance and gravitational force. Direct means if one increases, the other also increases while inverse means when one increases, the other decreases. Gravitational force increases when the mass of two objects increase and vice versa while gravitational force increases when the distance between two objects decreases and vice versa.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
