11. kat had a disagreement with paul and told him that he was an idiot. later, while apologizing, kat asked paul to “forget my comment.” kat does not realize that a) communication is irreversible. b) communication is a process. c) ethical communication is imperative. d) choices have consequences. e) self-disclosure is needed.

It would be A, because Kat cannot literally take back what she said.

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.
