Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.
Answer:
(D) Block RNA and DNA synthesis.
Explanation:
Antibiotics conquer foreign bodies and germs through the process of Phagocytosis, nicknamed cell eating. this basically a process involving the surrounding of the invading cell and pentrating through the Cell wall and thus weakening the cell's overall structure.
