Because the Europeans had already been exposed to the diseases and had built an immunity to it, and the Native Americans hadn't, hope this helps
Sedatives and Hypnotics depress the central nervous system by interfering with the transmission of nerve impulses.
Like alcohol, sedatives and hypnotics are depressants that depress the central nervous system. Since long-term exposure to alcohol can lead to the development of depression, chronic use of sedatives and hypnotics, as demonstrated by several neurobiological and imaging studies
Long-term use of sedatives can cause side effects such as Psychiatric disorders such as anxiety.
It has been suggested that treating depression and anxiety with sedatives/hypnotics, especially benzodiazepines, may reduce the risk in the first few weeks. Sedatives/hypnotics also have inhibitory and disinhibitory properties, but these may increase the risk

Answer:
FDR was the first, and last, president to win more than two consecutive presidential elections and his exclusive four terms were in part a consequence of timing. His election for a third term took place as the United States remained in the throes of the Great Depression and World War II had just begun. While multiple presidents had sought third terms before, the instability of the times allowed FDR to make a strong case for stability.
Eventually U.S. lawmakers pushed back, arguing that term limits were necessary to keep abuse of power in check. Two years after FDR’s death, Congress passed the 22nd Amendment, limiting presidents to two terms. Then amendment was then ratified in 1951.
At the time of FDR’s third presidential run, however, “There was nothing but precedent standing in his way,” says Perry. “But, still, precedent, especially as it relates to the presidency, can be pretty powerful.”es and you have foreign policy with the outbreak of World War II in 1939,” says Barbara Perry, professor and director of presidential studies at the University of Virginia’s Miller Center. “And then you have his own political viability—he had won the 1936 election with more than two-thirds of the popular vote.
Farmers needed to control their water supply because they can either have too much water or too little. Too much and their crops drown, too little and they dry up. Another reason is because they needed to provide dams to control flooding when rivers overflowed when things thawed in the spring, or during heavy rain fall, and to be able to have water during a drought. Speaking of a drought, they can use up too much water and cause a drought in big farming areas. Hopes this answers your question!
