Bulgarian yogurt contained which species? correct answer: lactobacillus bulgaricus and streptococcus thermophilus Tissier - 1899 correct answer: identified bifidobacteria and promoted therapeutic use for treating infant diarrhea. Metchnikoff - 1907 correct answer: Proposed that the acid producing bacteria in fermented milk products could prevent "fouling" in the large intestine and lead to a longer life. He suggested that the bacteria (lactobacillus and strep) in yogurt suppress the b...

adaptative radiation - diversification of a group of organisms into forms filling different ecological niches allopatric speciation - aka geographical isolation: biological pops of the same species become isolated from each other to an extent that prevents or interferes with gene flow allopolyploidy - individual or strain whose chromosomes are composed of more than two genomes each of which has been derived more or less complete but possibly modified from one of two or more species -matin...

Why are bacteria an excellent tool for genetic research? -Grow extremely quickly -Very easy to isolate one species or strain of bacteria, typically through the selection of antibiotic-resistant strains -Bacteria can be grown in almost any laboratory, typically with little risk, and their source of nourishment is extremely inexpensive 2. Spontaneous mutation Refers to the process by which bacteria undergo random mutations, some of which may be advantageous to survival in an otherwise h...
