1.A car is accelerating down a slope. What are the changes in kinetic energy and gravitational potential energy as it is moving down the slope? A. Kinetic energy incresses as gravitational potential energy decreases
B. Kinetic energy decreases as gravitational potentail energy increases
C. Kinetic energy increases as gravitational potentail energy increases
D. Kinetic energy decreases as gravitational potentail decreases

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."

i think the answer is b.

condensation. good luck!
