Which isotopic ratio needs to be determined

Chemistry
1 answer:
Nina [5.8K]3 years ago
4 0

Answer: (4) C-14 to 6-12

Explanation:

Carbon dating is used to estimate the age of wooden trees which use carbon dioxide. Carbon has three naturally occurring isotopes.C-12 and C-13 are stable but C-14 is radioactive. C-14 decays to nitrogen-14 and has a half-life of 5,730 years.

Wooden trees naturally incorporate both the C-12 and C-14 during their lifetimes. When wooden trees die, it stops consuming more of radioactive carbon while the C-14 which is already present in them continues to decay back into nitrogen. With the help of C-12 to C-14 ratio, we can estimate the age of wooden objects.

Describe the relationship between an enzyme, substrate, and active site.
alexdok [17]
So what I know is that enzyme and substrate are like lock and key meaning that when the active site of the enzyme changes, the enzyme will not fit to the substrate which will lead the enzyme to denature. Hope this helps.

In sexually reproduction, how many do the offspring compare to the parents?
tatuchka [14]
In sexual reproduction the offspring has similar genetics and look of those of the parents. In asexual reproduction, it will look like the one parent, but it won't have the parent. The parent would have split in two and created two daughter cells, but when they make buds of them they have one child and on parent. Hope I helped! ;)
