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.
It’s to little I can not see it
Answer:
Trichromatic vision.
Explanation:
Trichromatic theory may be defined as the theory that posses of three independent channels that are used to convey the color information. They are derived from the three different cone cells.
The television also produce three primary colors by the use of trichromatic theory. The receptor or these colors in human are greater than three as different colors have different intensity of light. The opsin protein plays an important role in the trichromatic vision.
Thus, the answer is trichromatic vision.
