Answer:
Plants and animals assimilate carbon-14 from carbon dioxide throughout their life. When they die, they stop exchanging carbon with the biosphere and their carbon-14 content begins to decrease at a rate determined by the law of radioactive decay.
Radiocarbon dating is basically a method designed to measure residual radioactivity.
Explanation:
Carbon-14 is a weakly radioactive carbon isotope; It is also known as radiocarbon, and is an isotopic stopwatch.
Radiocarbon dating is only applicable to organic materials and some inorganic materials (not applicable to metals).
Proportional gas counting, liquid scintillation counting, and accelerator mass spectrometry are the three main methods of radiocarbon dating.
The radiocarbon, or carbon-14, is an isotope of the carbon element that is unstable and weakly radioactive. The stable isotopes are carbon-12 and carbon-13.
Carbon 14 is continuously formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen-14 atoms, rapidly oxidizing in the air to form carbon dioxide and entering the global carbon cycle.
Accelerator mass spectrometry (AMS) is a modern method of radiocarbon dating that is considered the most efficient way to measure the radiocarbon content of a sample. In this method, the content of carbon-14 is measured directly in relation to carbon-12 and carbon-13 present. The method does not take into account beta particles, but the number of carbon atoms present in the sample and the proportion of the isotopes.

yes its important because...
Explanation:
Water is an essential feature of homeostasis in an organism. Water increases the volume of blood, which affects blood pressure and heart rate. Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide. Water can be excreted, so it carries toxins that have been made water-soluble out of the body.

Answer:
Recycled, not recycled
Explanation:
In a soil ecosystem, matter is recycled and energy isn't recycled.
Matter is recycled through biogeochemical cycles. Matter has to be recycled because it can neither be created, nor destroyed, and as such, recycling is the only option left.
Energy isn't recycled because most of the energy gotten is used by organisms, as gotten from the plants already, and thus, when it gets to the food chain there isn't much left to be recycled.

Explanation:
Viruses are a limitation to cell theory.
According to cell theory, all cells arise from pre - existing cells. But viruses lack any membranes and do not show the characteristics of life unless they enter a living body and use its cell machinery to multiply.

Aristotle illustrates virtue in a way distinct from what one is usually taught in school, but it is much closer to how one thinks on a regular basis. One is usually taught that courage is the contrary of cowardice, and generosity is the reverse of miserliness and others.
Although, Aristotle illustrates virtue as the mean between the two extremes, which requires to be avoided. For Aristotle, virtue is the golden mean between the two extremes. Though the mean is not a strict arithmetic mean. Virtue comes in between the two extremes, but where it actually comes depends on a very large extent to a particular situation.
Answer:
Aristotle defines a virtue as a habit that requires practice.
Explanation:
Moreover, as with any habit, becoming virtuous requires practice, repeatedly doing similar kinds of things until it becomes second nature.
