Which of the following credit scores is a normal credit score? a. 650 b. 500 c. 775 d. 400

the most average american has a credit score of around A. it is pretty debatable but this is the average score... hope that this helps

It would be A.) 650.

For a score with a range between 300-850, a credit score of 700 or above is  650-699, Fair.

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."

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
