Answer from: keith1577621

The correct answer is B. allele

Explanation:

Alleles are the multiple forms of a single gene that can be inherited into the next generation. A gene can contain multiple alleles like for height we have 2 alleles one for short height and one for long height.

Some genes have more than 2 alleles like in case of blood group we have 3 alleles of a gene A, B, and O. Some alleles are dominant and some are recessive. Dominant allele repress the expression of recessive alleles.

Allele from two different genes are independently assorted during the gamete formation. The homozygous chromosome contains the same gene set in the same sequence that may contain identical or non-identical allele.

Therefore, allele is the inheritable form of a single gene so the correct answer is C.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
