By definition, if the DNA of a cell undergoes a spontaneous mutation, is not due to <u>exposure to radiation.</u>

Spontaneous mutations are derived from various sources, which include mistakes made all through the replication of undamaged template DNA, mutagenic nucleotide substrates, and endogenous DNA lesions.
Spontaneous mutation, also referred to as background mutation can be defined as genetic modifications that arise inside the absence of mutagens and haven't any recognized reason.
It is able to result from sports of a normal cellular, including mistakes or errors during DNA replication.

Mortality is a data piece for a demographer that would be interested in studying demography. It is fundamental to estimate population size.
<h3>What is mortality in demography?</h3>
Mortality refers to the rate of deads in a given population for a particular period of time (often one year calendar).
Conversely, the birth rate refers to the rate of births in a given population for a particular period of time.
Demography is a discipline that studies human population dynamics, which includes both mortality and birth rates.
