Is it true that radioactive dating means putting everything in proper sequence?
No. It means finding out the date something was created or died or placed by comparing the amount of certain radioactive isotopes to those expected of an original object before death or placement.
Will you die if you inhale dry ice fumes?
Dry ice is solid form of carbon dioxide. Carbon dioxide will not kill you unless there is a sufficent amount present to replace the oxygen in the air around you. This will result in death by suffocation or asphyxiation.
Can humans eliminate your exposure to radiation?
Since this a science question: we probably will never eliminate exposure to radiation. Besides the radiation we have caused, there is normal natural tradition. There is also something called background radiation which is part of our world.
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.
How does radioactive carbon dating help determine the age of fossils?
Living things take in carbon from food.
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 a scientist who uses carbon-14 dating actually measuring?
A scientist who uses carbon-14 dating is measuring the amount of carbon-14 present in a sample. Carbon-14 is a radioactive isotope of carbon that decays over time, allowing scientists to determine the age of organic materials.
Is it true that radioactive dating means putting everything in proper sequence?
No. It means finding out the date something was created or died or placed by comparing the amount of certain radioactive isotopes to those expected of an original object before death or placement.
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.

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

What is the c-14 c-12 ratio used to date once living organisms?
It is because living organisms absorb C14 from their environment. After death, they are no longer capable of absorbing any more C14. So, at the time of death, the C14 : C12 ratio is fixed. C14 undergoes radioactive decay (into C12) so the C14 : C12 ratio declines and that can be used as a measure of the time since death.
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
