Millennials. With immigration adding more numbers to its group than any other, the Millennial population is projected to peak in 2036 at 81.1 million. Thereafter the oldest Millennial will be at least 56 years of age and mortality is projected to outweigh net immigration. By 2050 there will be a projected 79.2 million Millennials. Generation X
A mutagen is defined as any chemical that can cause changes in the DNA sequence of an organism. These changes are called mutations ( hence mutation + genos (creator) = mutagen ). Some mutagens are well-known: For example UV radiation. UV has enoug...
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens.n Ames test, where the varying concentrations of the chemical are used in the test, the dose response curve obtained is nearly always linear, suggesting that there is no threshold for mutagenesis. Similar results are also obtained in studies with radiations, indicating that there may be no safe threshold for mutagens.
