Each organelle, in a cell, works with all of the other organelles to maintain balance, or homeostasis. The organelles have specific functions such as the mitochondria, which create energy, and the ribosome, which translates RNA into proteins. Because these cells work together, the body is able to maintain homeostasis.

Answer:
Not good for such old age
Explanation:
Carbon 14's half-life is about 5,700 years. So, it cannot be used to date something more recent than that. Also, due to the decay, it cannot be used on items older than about 50,000 years.
Then youngest a sample from the precambrian era could be is about 541,000,000 years (541 millions), so it's WAY past the range of use of Carbon 14, since there wouldn't be any carbon 14 left in the sample to evaluate the age through C14's half-life cycle.
