Answer:
Ptolemy included epicycles in his orbits.
Explanation:
Ptolomy's model of the solar system was geocentric, where the sun, moon, planets, and stars all orbit the earth in perfectly circular orbits. The problem with perfectly circular orbit around the Earth is that they do not explain the occasional backward motion, or retrograde motion, of the planets.
The Greeks insisted that the motion of the planets be perfectly circular. Ptolemy modeled the planets making small circles around a point that orbited the Earth. These smaller circles were called epicycles, and they allowed the planets to move backward relative to the background stars.
Agree
it is no active to use energy to move or be in motion
Answer:
A. They are have a limitless growth potential, in part due to their ability to maintain telomere length, and in culture will continue to divide indefinitely.
Explanation:
Unlike normal cells, telomeres shorten in every cell division until eventually they become too short to protect the chromosomes and the cell dies. Cancer cells reverse the telomeres shortening, and instead, they lengthen them, thus they become inmortal.
