Explanation:
Answer:
PCR is used in many research labs, and it also has practical applications in forensics, genetic testing, and diagnostics. For instance, PCR is used to amplify genes associated with genetic disorders from the DNA of patients (or from fetal DNA, in the case of prenatal testing).
Answer:
D. The amount of sulfur emitted by a smokestack before and after the scrubber is attached
Answer:
Reticulation
Explanation:
Reticulation is a process which explains the origin of many organisms formed by the merging of the two lineages. The species are formed when the species in the evolutionary process got scattered, formed two lineages and then again reproduced and merged.
Studies suggest that the origin of many species in the angiosperm phylum is the result of the process of the reticulation.
Thus, Reticulation is the correct answer.
