Radioactive dating involves determining which of the following? half-life decay index fossils depth of layers geologic time

The correct answer is half-life decay.  

A method of determining the age of a specimen of a mineral by finding the relative concentrations of certain radioactive elements present is known as radiometric dating or radioactive dating. In this age signifies the elapsed time from when the specimen of mineral was produced.  

The radioactive elements decay by half-lives, that is, if a half-life is equivalent to one year, then one half of the radioactive element will have decayed in the first year after the formation of mineral, and the other half will decay in the next year, and so on.  

raits that your monster will have. the dna code for each trait is given, so you will need to go through the process of transcription and translation to determine what protein is being made and then match that with the corresponding trait. you may even include a picture of your monster if you are feeling creati
