Plasma membrane is the answer
Is there a picture of the isotope or?- becaue I can’t help if I don’t have a visual.
Answer: 2948
Explanation:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = age of sample = ?
a = let initial amount of the reactant = 100
a - x = amount left after decay process = 
Thus the fossil is 2948 years old.
Because they both have to do with and chemistry science
