I will give 25 points(thats all of mine)

Plants take in carbon dioxide to do photosynthesis and gives off oxygen, the sheep in the field breathes in the oxygen the plants made.  When the sheep dies, it would put carbon into the soil by decomposition.  The powerplant will use the fossil fuel in the soil to create power, and ends up putting carbon in the air again.  The stages repeats again and again.

yes you are doing it right great gob

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."
