What makes water a polar molecule? A. The liquid nature of water
B. The equal forces between oxygen and hydrogen
C. The uneven bend in the bond between oxygen and hydrogen
D. The ionic bond between the oxygen and hydrogen

C. The uneven bend in the bond between oxygen and hydrogen

Explanation:

A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.v
