Ответ:
Answer : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
Explanation :
Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
All radioactive decays follow first order kinetics.
The relation between the half-life and rate constant is:
The half-life of the radioactive isotope is remains the same that means a constant value and it is not affected by any external conditions.

Explanation:
Mitosis is the process of reproduction of somatic/body cells. This means that the number of chromosomes the original (parent) cell started out with, will remain the same for the daughter cells.
Given that if a parent cell has 3 chromosomes before mitosis, then the 2 daughter cells produced will also have 3 chromosomes after mitosis and cytokinesis.
