A structure that looks the same and does the same job but was not present in a common ancestor is termed:.

The correct answer is - analogous.

Explanation:

Analogous structures or organs are the structures with the same look which is developed to perform the same job and not present because inherited by a common ancestor.

These structures are present in unrelated organisms and look the same from outside and perform the same action for example wings of bat and birds look and perform the same action but not inherited from a common ancestor.

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.
