Which of the following is a technique used in absolute dating?
index fossil correlation
original horizontality
radiocarbon dating
superposition

The correct answer is Radiocarbon dating

Absolute dating is used to determine the absolute age of the fossil. Radiocarbon dating is used to determine the absolute age of the fossil, by using carbon dating we calculate the amount of carbon left in the organic matter(fossil). The cosmic radiation entering the earth produces C-14 moves up in the food chain and as plants use carbon atoms present in the atmosphere for photosynthesis and this carbon is transferred from plants to animals. This carbon takes 5730 years to decay into half and convert into nitrogen. This is how we know the age of carbon and the amount of carbon left in the fossil determines the age of the fossil absolutely.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

a axis of a graph is a color or shade so we can all go outside and have a party so we can eat   some grilled cheese sammiches and broccoli and have some ugly fun times

i don't know why i put this, i know its not the i was just bored : p
