The life cycle that becomes more dominant as plants become more complex

The correct answer is sporophyte.

The plants, the gametophyte is the haploid and the sporophyte is the diploid. In the life cycle plants gametophyte is alternates with sporophyte. In complex plants, sporophytes have evolved to become larger, dominant and longer-lived compared to gametophytes. This phase undergoes meiosis and produce spores. Spores germinate to form gametophyte.

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."

condensation. good luck!
