Answer: Potassium-40 decays into argon gas over time.
Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.
Potassium-40 undergoes decay following first order kinetics as given below:
Hi Geny!
Question - Describe the cell theory and the developments that led to the cell theory.
Answer:

- Each and every organism is wither unicellular or multicellular.
- The basic unit of life is the cell.
- Cells are created from cells that had existed previously.
There were 3 scientists that made cell theory each of the 3 components of above were the 3 scientists.

Hope This Helps :)
Answer:
No. China is already consuming third of the world's coal production for electricity, which is a serious challenge to the environmental. The trade off is fair so China should build the new dam.
A general ballpark how one can predict the way how evolution will work in the future would be by thinking about the requirement of a certain area or environment and which changes would be necessary and relevant for any organism to thrive with its new changes.
This could help people speeden up this process by enabling organisms to develop such traits faster, as well as ourselves.
