Help please Luminosity is the amount of energy emitted by a star each second. Stars radiate light over a broad range of frequencies in the electromagnetic spectrum, from the low energy radio waves to high energy gamma rays. The luminosity of a star depends on two factors:
A)age and surface area.
B)surface area and temperature.
C)gravity and distance from Earth.
D)distance from Earth and temperature.

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."
