A roller coaster car runs completely on the gravitational potential energy it stores as it is towed up to the top of the first hill and then released. No other hill can be as high as the first hill because there will not be enough kinetic energy to reach the top.

A. Some of the energy is transformed into heat, which is then transferred to the surrounding environment or the metal roller coaster tracks.
B. Some of the energy is destroyed due to friction as the car moves along the tracks.
C. Some of the energy is sent back to the battery along transmission wires and stored there for the next ride.
D. Some of the energy is transformed into potential energy and stored in the car as it moves along the tracks.

Hundreds of years ago, people thought living organisms began life spontaneously. When flies were observed on a piece of dead meat, it was thought that the flies had spontaneously arose from the meat.
In that time, it was not understood that flies had laid eggs on the meat and that the hatched eggs is where the flies they saw had come from. Since that time, the Cell Theory was developed.

Which part of the Cell Theory would the idea of spontaneous life contradict?
