What three traits are used to classify organisms? A
Cell type, how they create energy, number of cells they have
B
Cell type, if they're living or dead, the number of organs they have
С
How they create energy, how many years they live, how big they are
D
The number of cells they have, the number of years they live, the number of
offspring they produce

Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things.

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."
