Describe how the between gravitational force between any two objects is affected by the distance between them

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

it would lead to upper respiratory infections and pneumonia.

not sure if this is what you'r looking for eubacteria and archaebacteria
