Rebekah is studying a molecule and trying to determine if it is DNA or RNA. Which kind of molecule is she studying?

Rebekah is studying a molecule of nucleic acid

Step-by-step explanation:

The simplest form of DNA or RNA is nucleic acid as it forms the basis of DNA and RNA, so from the analogy above it shows Rebekah is studying nucleic acid since she is studying either RNA or DNA

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
