Carbon 14 dating bomb curve
After the death of the organism the exchange with the environment stops and also the uptake of Reservoir age The equilibrium ratio is not everywhere the same on earth.
This causes apparent age differences, known as reservoir ages.
(Isotopes are versions of elements that have differing numbers of neutrons in their nuclei.) Knowing the age of elephant tusks is important, since many regulations of ivory trade are date-specific.
Organisms take up carbon during their life and so obtain the equilibrium value from the environment.
During the growth the carbon and its ratio becomes fixed in cells of plants, animals and humans.
Probiotics are "good" bacteria sold in pharmacies, to be taken alongside antibiotics to protect your intestinal microbiome. How come otorhinolaryngology is a single discipline if it concerns three different body parts? Are there other examples of specialties that include multiple minor subspecialties?
How do they survive without food in a paper envelope for years?
