How does radioactive carbon dating help determine the age of fossils?
Living things take in carbon from food.
How is the amount of carbon-14 in an artifact related to its age?
The level of carbon 14 in an artefact reduces by 50% every 5730 years from the moment that the raw material from which the artefact is made no longer is exchanging carbon with he atmosphere, in most cases this is the point of death of the animal or plant.
Which gas can suffocate living beings to death?
Carbon monoxide is a gas that can suffocate living beings to death because it binds with hemoglobin in the blood, reducing the amount of oxygen that can be carried to the tissues.
What is the average amount of carbon monoxide a human body needs?
The average amount of carbon monoxide a human body needs is zero. Carbon monoxide is a toxic gas that can interfere with the body's ability to transport oxygen, leading to serious health effects or even death. It is important to minimize exposure to carbon monoxide to ensure health and safety.
Which two substances are involved in carbon-14 dating?
Carbon-14 dating primarily involves carbon-14 (¹⁴C) and carbon dioxide (CO₂). Living organisms absorb carbon from the atmosphere, including a small proportion of carbon-14. When they die, they stop taking in carbon, and the carbon-14 they contain begins to decay at a known rate, allowing scientists to estimate the time since death based on the remaining amount of carbon-14.
How does carbon dating work ma?
Carbon dating works by measuring the amount of radioactive carbon-14 in a sample. Carbon-14 is present in all living organisms and decays at a known rate after death. By comparing the amount of carbon-14 remaining in a sample to the amount in living organisms, scientists can determine the sample's age.

What is carbon datting?
Carbon has several different forms- one being Carbon 14, which is mildly radioactive. Carbon dating measures the amount of Carbon 14 in a formerly living thing, and makes it possible to determine roughly how old the thing is.

What is a scientist who uses carbon-14 dating actually measuring?
In all cases the scientist is trying to measure the amount of radioactive decay of carbon-14 isotopes in order to establish the amount of time that has passed since the death of a living thing. As such all methods are based on establishing the remaining carbon-14 in a sample. However the specific type of carbon-14 dating being used will dictate how this is done.In the traditional approach the scientist is actually measuring the levels of beta activity from a sample. This is given off by the carbon-14 and so the amount of carbon-14 is established as the beta particles are used to identify the ratio of carbon-14 to its non-radioactive carbon-12.More modern methods use accelerator mass spectrometry and an atom counting approach to actually measure number of atoms of carbon-14 in a sample. This is generally more precise, although often significantly more costly, and both methods are still in use depending on the lab.
How does carbon 14 work?
From Wikipedia (see the Related Link below):By emitting an electron and an anti-neutrino, carbon-14 is changed into stable (non-radioactive) nitrogen-14. This decay can be used to get a measure of how long ago a piece of once-living material died. However, aquatic plants obtain some of their carbon from dissolved carbonates which are likely to be very old, and thus deficient in the carbon-14 isotope, so the method is less reliable for such materials as well as for samples derived from animals with such plants in their food chain.The reaction is:146C ---> 147N + e- + antineutrino
Wolves are predators for hares The wolf population increase what happens next?
The Death Rate of hares increases.
How can carbon-14 dating provide the age of a dead animal or plant?
The half-life of carbon is known in living organisms- the amount of carbon-14 remains constant, after death. no new carbon-14 enters the organism, scientists measure the proportion of carbon-14 in the organism and calculate how it differs from the amount that would have been there if the organism would be alive, from this differenct, they determine the age.

Is uranium a nutrient?
No, Uranium is a rare-ish element whose radioactive isotope is often used in nuclear reactors. ingestion of radioactive elements can result in death
