Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
DNA ligase is like the glue that pieces together DNA. DNA polymerase "unzips" the DNA helix in DNA replication.
Answer:
What are the options and what are the different celestial bodies?
Explanation:
you can't expect someone to fully answer a question where they need more information to answer it in the first place> if you edit your answer, you should be able to add those needed pieces of information to the question!
that or you might get flagged for having a confusing or incomplete answer, i wouldn't do that i'm just warning you for future reference!
