The students in ms. hill's science class were investigating the properties of water. they placed a piece of celery in a beaker of blue water. the next day, the celery was no longer green, but blue, all the way up to the leaves. what property of water best explains why the blue water moved up the celery stalk? a. bouyancy b. specific heat c. surfece tension d. capillary action

D. Capillary action                                                                  

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."
