Answer from: Aprilbtrippin2004

Nucleic acids offer variability because they contain alternate forms of genes called as alleles. Alleles are the alternate forms of genes, and are a variant form of genes, which are found at the same place (called as locus), on the chromosome, and may form due to mutation. If both alleles are same, then an organism is homozygous for the character expressed y those alleles. If both alleles are different, then the organism is said to be heterozygous for that condition, and only dominant allele will express itself, resulting in the production of the dominant phenotypic character.

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.
