Answer:Thus we can conclude that these charcoal fragments are about 11460 years old.
Explanation:
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.
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 = 25
b) for completion of 75 % of reaction
Thus we can conclude that these charcoal fragments are about 11460 years old.
the insertion on removal of mutations are dangerous in nature. the process is basically just one large gamble to see what it does. and even though we have a decent understanding of the genomes of many animals and plants, we still dont know everything. so if we tamper with certain genes we may cause a evolution or we might kill the subject and the potential for it to procreate.
Answer: B
Explanation:
I think it is either A, B. I think it is B because Butter is a saturated fat and is saturated with hydrogens. This makes it solid. They are made from animal fats that contain saturated fatty acids that are solid at room temperature. Soft margarine is made of plant fats which remain liquid at room temperatures like the corn oil. -I searched this up UnU Hope this helps.
