How is radioactive decay related to radiometric dating

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.

Explanation: It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

i think that the best answer would be c.

tell me if im wrong : )

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
