The character in "Old Yeller" who is considered mighty nice and polite is D. Burn Sanderson. The narrator says that he would always take "his hat off to Mama when he dismounted in front of our cabin." This is how the narrator remembers this character, and he doesn't describe the other options that way, so only D is the correct answer.

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.

Iam not sure sorry
