The classical example of thermionic emission is the emission of electrons from a hot cathode into a vacuum (also known as thermal electron emission or the Edison effect) in a vacuum tube. The hot cathode can be a metal filament, a coated metal filament, or a separate structure of metal or carbides or borides of transition metals.
Low confidence regions are areas for which there s a small amount of DNA evidence found in your sample. All ethnicities with predicted percentages of less than 4.5% appear as low confidence regions. Inferior complex is low complex .
Birds have much less DNA than mammals primarily because they do not possess nearly as much repetitive DNA, he noted. Genome sequencing may shed light on parrots' longevity and intelligence After completely sequencing the immensely repetitive DNA in the human genome's one million nucleotide-long immunoglobulin heavy (IGH)-chain locus, these scientists have also found ethnicity may influence immunity.
