In geology, the Radioactive dating is significant because its provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
<h3>What is a Radioactive dating?</h3>
This refers to the technique that is used to know the date of materials such as rocks or carbon in which the trace radioactive impurities were selectively incorporated when they were formed.
It determines the dating of rocks and minerals through the use of a radioactive isotopes, it is also useful for igneous and metamorphic rocks that cannot be dated by the stratigraphic correlation method.
As the carbon dating helps to determine the age of an object containing organic material by using the properties of its radiocarbon, it is considered a poor tool for finding the age of the dinosaur skull in the purple layer because the collagen in the dinosaur's bone has usually long since decayed away and is therefore unavailable for radiocarbon dating.

Answer:
it is a good way
Explanation:
It is a good way to gather demographic information because it's very accurate. Censucount.org says that "The Census Bureau reported a net national overcount of 0.01% in 2010" which means they are only off by a little, but still effective. THe demographic information is then used to decide where to distribute the funds and taxes for schools, public areas, supermarkets, etc.
The answer is National security because the citizens need to know that they are being protected, and usually also how they are being protected. But the government often needs so measure of secrecy in order to protect National Security. If the government were to tell citizens exactly how they were being protected and someone posted it onto the internet it would severely compromise that protection. However people do not generally seem to understand that and tensions become heated between the two groups. Both sides reasons are perfectly legitimate, but one outweighs the other by knowledge. The answer is B.
