The Research , publishedintheproceedings of the Royal Society B, has investigated the bacterium in eleven individuals ranging from as far back as the Bronze age up to the twentieth century. Samples have been taken from individuals in Europe and in both pre and post-colonial America. The oldest case study was that of an individual from 1200 BC, found in Burial cave in Mountainsell (Licidia, Catalonia). The study found that ancient genetic material from principle Bacterium, streptococcus mutant, cause dental carries. The mutant has increased its genetic material change overtime. This is possibly due to the coincidence of dietary changes that are linked with the expansion of humanity. Similar study conducted by researchers from the University Autonma de Barcelona (UAB) and laboratoria Nasional de Genomica para la Bie diversided, Mexico, putthe genetic material in order and found that genetic diversity has been produced, especially in the fragment of a gene that codifies a virulence factor known as dextranase
What is the first paragraph about?
A. The research genetic diversity
B. The investigation ofdental carries
C. The investigation of Bacterium
D. The samples of indivuduals from pre colonial Europe
E. The investigation of the bacterium in eleven individuals.
Pada teks disebutkan Theresearch, published in the proceedings of the royal society B, has investigated the bacterium in eleven individuals, yaitu peneliti telah melakukan penelitian terhadap sebelas individu. Jadi, jawaban yang tepat adalah The investigation of the bacterium in eleven individuals.
