Answer:

Asegment of chromosomal DNA

Explanation:

A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes. It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person's unique physical features.

how would you answer a person who says that the geologic column gives support for an earth that is at least 4.6 billion years ol
olasank [31]
<span>The geologic column is a graphic representation of the layers of rock that make up the earth’s crust. By compiling data from local areas, scientists have constructed a composite picture of the earth. Evolutionists would have us believe that this is also a picture of the 4.5 billion year history of the earth. Using a bit of circular reasoning, the geologic column is used as support for biologic evolution, which is then sometimes used to confirm the order of the layers in the geologic column.</span>
