Answer: The age of a bone or other sample of organic matter by its carbon-14 content is 16252 years
Explanation:
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
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for completion of 14 % of reaction
The age of a bone or other sample of organic matter by its carbon-14 content is 16252 years
Question

Explanation:
<span>c ribosomes. lots and lots of ribosomes. Thousands of these protein forming organells and in the cytoplasm. When they are on the ER it is called rough ER (because of its sandpaper like appearence). Rough ER makes proteins either for inside the cell (to another organell) or outside the cell. If the ER does not have ribosomes, it is smooth ER. Smooth ER makes lipidds and steroids.</span>
I believe the answer is minerals.
Minerals are inorganic substances that the body cannot manufacture but that act as catalysts, regulating many vital body processes. Nutrients are substances in food that the body needs to function properly to grow, repair, and supply it with energy. These includes, carbohydrates, proteins, lipids, vitamins and minerals.
