Okay, biology isn't exactly my strongest subject (it never has been), but I'm pretty sure the answer is nucleotides. DNA is made up of nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. There are four different nitrogen bases: adenine (A), thymine (T), guanine (G), and cytosine (C). A always pairs with T, and G always pairs with C.
I think the correct answer from the choices listed above is option A. The relationship between the themes of “place” and “human-environment interaction” is that the characteristics <span>of “place” include things like economic activity, architecture, and culture, all of which are human elements that alter or can be influenced by the environment. </span>
