Simple carbon dating explanation

What if originally part of the material being measured was already carbon 12? Since we do not know what was there originally, the dates may be very far from correct."p58 "Experiments have shown that carbon 14, for instance, does change into carbon 12 at different rates, depending on factors like heat and radiation.

Also, we know that high electric voltages definitely change the rate of decay of many elements." I thought it worked like this:-there are several isotopes of carbon in the atmosphere-living things exchange carbon with the atmosphere until they die at which point they do not take on any more carbon-the carbon 14 undergoes radioactive decay to nitrogen 14-the carbon 12 is stable and does not undergo decay-measuring the amount of carbon 14 and carbon 12 in a sample and calculating the current ratio allows you to determine how long ago the organism died (since the ratio of carbon 14 to carbon 12 in the atmosphere does change some over time, you need to use a calibration curve...these are developed by measuring carbon ratios in tree rings and other once living things that can be dated by other methods) I could not find anything about decay rates changing based on heat or radiation and the author gives no source so should I doubt that statement also??

Carbon has all of the functions inherited from the base Date Time class.

This approach allows you to access the base functionality if you see anything missing in Carbon but is there in Date Time.

I was used to seeing active ingredients in 2% solutions, to moderate their effects.

The plant name and unusually high concentration of witch hazel stood out as red flags.

their bodies are decomposed by decomposers, and some are converted into FOSSIL fuels, while some other are carried into the bottom of the oceans, where they form rocks. also, all plants and animals, release carbon Dioxide into the atmosphere as a by product of CELLULAR RESPIRATIOn.
