Two nuclei's produced by mitosis of nucleus are

At a given time there are25% undecayed nuclei in a sample. After 10 second number of undecayed nuclei reduces to 12.5% . Then mean life of the nuclei will be about

A nucleus with A = 235 splits into two nuclei whose mass numbers are in the ratio 2 : 1. Ratio of heavier nuclei is

Half lives of two radioactive substances are 20 and 40 minutes respectively. Initially samples were having equal number of nuclei. After 80 minutes ratio of the remaining numbers of A and B nuclei wil

Considering cell replacement by mitosis, cells that are replaced by mitosis are

A process in which nuclei of a radioactive atom are split into smaller nuclei is known as
