Answer:
A gene mutations can be defined as the permanent alteration in the sequence of the DNA that makes the gene. Gene mutation may give rise to genetic variations or from the genetic recombination. These variations are known to alter the gene activity and the function of the protein. These variations in the protein or gene activity give rise to different traits in an organism.
If the trait is beneficial and helps the organism to survive and reproduce, such variation is likely to be passed to the next generation.

The correct answer is buildup of toxins.
One of the essential action of the liver is to process various kinds of toxins and to eliminate it out of the system of the organism. Although it is known as a toxin processor, it is not resistant to the toxins itself. As the liver is the main site for drug decontamination and stimulation, thus, the improper functioning of the liver may lead to the accumulation of toxins.
The geographic poles both wander statement is true.
<u>Explanation:</u>
Earth has geographic North and south poles as well as <em>magnetic south and North poles.</em> Magnetic North is geographic south and magnetic South is geographic North. The Geographic <em>poles of the earth</em> doesn’t remain stationary
Occurrence of perturbations in the earth’s movement doesn’t allow the geographic poles of <em>earth to remain stationary</em>. Over a period of few years the earth’s geographic poles move by few meters.
<em>Cartographic drawings</em> require stable <em>geographic poles</em> and thus use the averaged location of geographic poles.
