An organism stops taking in carbon when it dies.
It is generally determined by how long it has waisted away or if it has reached a certain disintegrating phase (an example would be a half-life). By learning how long a fossils minerals and dead cells have wasted away biologists can learn how old a fossil is relative to a period or our own time on earth.

They are mostly found on, or very near, the surface. They have probably been quite deeply buried at some point ( a lot can happen in, say, 70 million years) but due to tectonic movements and erosion, they finish up where we can find them. If all the Jurassic rocks were buried at about 300m, then our knowledge of dinosaurs would be impressively small.
By unit of length and distance and conversion ,we can say that 1 feet =12 in 4 feet =48 in ratio : 16 :48 1:3
I got this: "Unlike most fossil deposits, which consist of scattered bones accumulated over extended periods of time, the ash bed contains mostly articulated remains with bones still joined together in the proper order." From here: http://www-museum.unl.edu/research/vertpaleo/ashfall.html
12 is a single number. In so far as it can represent a ratio, it is a ratio of 12 to 1: a unit ratio.12 is a single number.

Means for every 100 units of one, you add 12 units of 2. Or a 20/3 ratio (expressed in percent).
To express 12 seconds to 1 minute as a ratio, we need to convert both units to the same time measurement. Since there are 60 seconds in 1 minute, the ratio would be 12:60. To simplify this ratio, we can divide both numbers by their greatest common factor, which is 12. This simplifies the ratio to 1:5.
There are 12 inches to 1 foot, so the ratio is 12 to 1.

The ratio of 12 to 24 can be simplified by dividing both numbers by their greatest common divisor, which is 12. This results in a simplified ratio of 1 to 2. Thus, the ratio of 12 to 24 is 1:2.
To find the ratio of 3 weeks to 12 days, we need to convert both time periods to the same unit. Since 1 week is equal to 7 days, 3 weeks is equivalent to 3 * 7 = 21 days. Therefore, the ratio of 3 weeks to 12 days is 21:12, which simplifies to 7:4.
It is 12 to 1.
12:1
12/10 = 6/5 The ratio is 6:5
The ratio is 4:5
12 × ratio = -18 → ratio = -18/12 = -3/2 = -1.5 Checking: -18 × ratio = -18 × -3/2 = 27 as required The common ratio is -3/2 (or -1.5)
