A shear wave (S wave) is a type of seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving.

Option A

Explanation:

Shear waves move through the body of an object, without following surface waves. These are called Secondary waves and S-waves. These are transverse too. Shear, as the name suggests, denotes a wave which is abnormal, i.e. perpendicular to the normal waves.

These normal waves are those which travel through the surface of the body. Unlike them, the S-waves travel move through the body, hence causes vibrations. These uncertain vibrations cause a body to shake, and therefore, the ground is shaken on the onset of shear waves. These are the causes of earth quakes.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

linnaeus is the father of taxonomy

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
