Explanation:
Genome is not a steady entity, it is exposed to various kinds of heritable modifications, a sudden and heritable modification in the arrangement of the genome in an organism, which produces different forms of any gene is called mutation.
The mutations provide the raw material for genetic evolution, mutation leads to the generation of alleles, in the absence of mutation all the genes would prevail only in one form, and the organism would lose to the tendency to evolve and amend with the changing environments.

Explanation:
Lateral-flow pregnancy test
It is a device use to confirm the prsence or the absence of the target analyte , which can be biomakers or the pathogens .
The very common type of lateral flow rapid test is the pregnancy test .
Lateral - flow technology uses colored nano particles , nitrocellulose membrane and antibodies to produce result of pregnancy .
As the sample is added , it flows along the test device passing via the conjugate pad to the nitrocellulose membrane and then to the absorbent pad.
The blue band on the control;l line and no band on the test line , gives a negative test of pregnancy .
