The answer is terracing.
Terracing is a type of landscaping characteristic for steep slopes and mountains. Graduated terraces are used to farm on this kind of terrain to reduce erosion. This way crops are planted on graduated level areas and not on steep terrain, and risk of surface runoff is reduced.
<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>
Answer:
C. Uncontrolled cell growth
Explanation:
Uncontrolled cell growth caused by mutations in genes that control the cell cycle. Cancer cells lack the ability to recognize and control cell growth and reproduction. As a result, they replicate again and again.
