Explanation:
Utilizing oxygen and nutrition, the mitochondria produce ATP, which serves as the cell's energy source. In a plant cell, photosynthesis takes place in the chloroplast.
Plant cells contain both the chloroplast and the mitochondrion, but animal cells only have the mitochondria. The purpose of mitochondria and chloroplasts is to produce energy for the cells in which they are found. Both types of organelles have an energy generation, or how inner and outer membrane as part of their structure. they change cellular energy into a certain form before the cell uses it, which is the fundamental commonality between mitochondria and chloroplast. 2. Chloroplast and mitochondrial DNA and RNA are nearly identical. Each DNA molecule is round.

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.
