Explanation:
English-The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.

Answer:The number of daughter atoms increase and the number of radioactive (parent) atoms decrease.
Explanation:
In the process of radioactive decay the unstable atom nuclei of the parent nucelus breaks down and split so as to release the daughter atoms or nuclei along with release of energy in the form of heat. Thus as the decay process proceeds the concentration of the parent atom decreases but the concentration of daughter atom increases.
