14. A scientist is using potassium-40, which is a radioactive isotope of
potassium, to discover the absolute age of a fossil by radiometric dating.
The scientist determines that about three-fourths of the original
potassium-40 atoms in the fossil now remain in the fossil. What additional
information is necessary for the scientist to determine the absolute age of
the fossil? *
the half-life of potassium-40
O O
the identity of an index fossil
the atomic mass of potassium-40
the total mass of the fossil

What happens as electrons move along the chain of molecules known as the electron transport chain? they gain energy, which causes atp molecules to lose phosphate groups. they gain energy, which causes h *ions to join with oxygen to produce water. they lose energy, which is then used by the cell to make atp. they lose energy, which is then used to break down atp.
