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
The answer is C. Damage to the region of the brain causes difficulty in alternating between two tasks a condition called adiadochokinesia. Other symptoms include abnormal eye movements, slurred speech and weak muscles. Approximately half of all brain neurons are located in the cerebellum.

plzzz mark as brainliest.
Explanation:
Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation.
Mutations that cause the altered codon to produce an amino acid with similar functionality (e.g. a mutation producing leucine instead of isoleucine) are often classified as silent; if the properties of the amino acid are conserved, this mutation does not usually significantly affect protein function.
I believe it's A j might be wrong though
