1:15 is the ratio of radioactive parent isotope to stable daughter isotope,
after four half-lives of decay.
Let:
- 'A' be the initial concentration of the radioactive parent isotope
- 'n' be the number of corresponding half-lives
- 'A/2ⁿ ' be the final concentration of the radioactive parent isotope
Using the Exponential Decay Relation:
A → A/2ⁿ ( after 'n' half-lives )
A⁴ → A/2⁴
A⁴ → A/16
∵The final concentration of the radioactive parent isotope is A/16.
∴The initial concentration of the stable daughter isotope will be 15A/16.
1:15 is the ratio of radioactive parent isotope to stable daughter isotope,
after four half-lives of decay.

ANSWER: A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle.
Explanation:
The word prokaryote comes from the Greek πρό (pro, 'before') and κάρυον (karyon, 'nut' or 'kernel'). Prokaryotes are divided into two domains, Archaea and Bacteria. Hope this helped!...
