The author proposes that lateral gene transfer can explain some of the evidence that is discordant with the traditional universal ancestor model. Analyze the role of lateral gene transfer at three different stages along the path of evolution. Use this statement rom the author to describe the stages "Evolution at the subcellular level can be viewed as a bridge between modern organismal evolution and the much earlier evolution that involved organic chemicals in an abiotic world."

ANSWER:

If the mass of an object is doubled, the gravitational force will also double.

EXPLANATION:

This is because the 'gravitational force' acting on a body is "directly proportional" to the "mass of the body". According to Newton’s Law of Gravity, a gravitational force equal to the mass of the body acts on the body and it is this gravitation force that attracts the body.

Therefore, gravitational force being directly proportional increases or decreases as the mass of the object increases or decreases.
