<span>The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years. This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago. After 5,730 years, the amount of carbon 14 left in the body is half of the original amount. If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.</span>
Because there is more Chlorophyll produced in larger amounts during summer. Chlorophyll is a greenish substance that makes leaves look green.
Hope it helped!

Explanation:
Females ovary always have a X chromosome.
Males sperms are of two types, they either have X chromosome or Y chromosome.
If X chromosome of males is involved in fission then, it results in XX chromosome set, it results in a female child.
If Y chromosome of males is involved in fission then, it results in XY chromosome set, it results in a male child.
The answer to this is B.Nuerons
When heat<span> is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The </span>motion<span> and spacing of the </span>particles<span> determines the state of matter of the substance. The end result of increased molecular </span>motion<span> is that the object expands and takes up more space.</span>
