During hot weather and vigorous exercise, people sweat. As the water on their skin evaporates, the water molecules absorb heat energy.
Explain why this process is important to the individual.

Explanation:

During hot weather or vigorous exercise people sweat. This is done to maintain the internal temperature of the body.

The phenomenon of maintaining the internal temperature of the body is necessary to keep the metabolism of the body all right. This is known as Homeostasis.

When the temperature inside the body increases beyond normal then sweating starts and heat is released out of the body in the form of sweat.

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).

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
