c. a soccer ball will not move until a player kicks it.

A body or object is in a state of continuous motion or in a state of rest unless an outside force is applied to it.

Newtons 2nd law :

Newtons second law states that the force applied is directly proportional to the mass of the body and the acceleration with which it travels.

Newtons 3rd law :

Every force applied has an equal and opposite force.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
