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
If scientists believe that the newly discovered gene has two alleles A and a and that the alleles show incomplete dominance, the best way to prove this is to look for subjects who are homozygous with respect to the different alleles. The offsprings will all have the genotype of Aa and if indeed, the alleles show incomplete the dominance, the traits of the first generation will not manifest completely but a mixture of two will.
I think it’s c. Hope you get it right!
