Unequal sharing results when there is significant difference in electronegativities. The more electronegative atom(s) draws bond electrons closer, leaving the less electronegaâ¦tive atom(s) slighty positive. The result of unequal sharing of electrons is the formation of polar bonds.

By 1831 cholera had arrived in Hamburg, and the first case in England was reported in October 1831 in Sunderland. The first case in East London was on 12 February, 1832.For all the fear attached to this new disease, only about 800 persons died of cholera in the East End.n the summer of 1831, after news had reached England that a cholera epidemic had arrived in the Baltic ports, Charles Greville said in his Memoirs [ chapter 15 ].
Definition. Cholera is an acute infectious disease characterized by watery diarrhea that is caused by the bacterium Vibrio cholerae, first identified by Robert Koch in 1883 during a cholera outbreak in Egypt.The name of the disease comes from a Greek word meaning flow of bile..ransmission. Vibrio cholerae is carried in the cholera victim's feces, urine, and vomitus, and is transmitted to others in contaminated water or food. Once it has reached the intestines, the intestinal lining becomes inflamed and the passages distended with a thin, watery fluid.
