<P0-S0> strict separation of powers did not operate in the united kingdom, the political structure of which served in most instances[citation needed] as a model for the government created by the u.s. <P0-S1> constitution. <P0-S2> [citation needed] under the uk westminster system, based on parliamentary sovereignty and responsible government, parliament (consisting of the sovereign (king-in-parliament), house of lords and house of commons) was the supreme lawmaking authority. <P0-S3> the executive branch acted in the name of the king ("his majesty's government"), as did the judiciary. <P0-S4> the king's ministers were in most cases members of one of the two houses of parliament, and the government needed to sustain the support of a majority in the house of commons. <P0-S5> one minister, the lord chancellor, was at the same time the sole judge in the court of chancery and the presiding officer in the house of lords. <P0-S6> therefore, it may be seen that the three branches of british government often violated the strict principle of separation of powers, even though there were many occasions when the different branches of the government disagreed with each other. <P0-S7> some u.s. states did not observe a strict separation of powers in the 18th century. <P0-S8> in new jersey, the governor also functioned as a member of the state's highest court and as the presiding officer of one house of the new jersey legislature. <P0-S9> the president of delaware was a member of the court of appeals; the presiding officers of the two houses of the state legislature also served in the executive department as vice presidents. <P0-S10> in both delaware and pennsylvania, members of the executive council served at the same time as judges. <P0-S11> on the other hand, many southern states explicitly required separation of powers. <P0-S12> maryland, virginia, north carolina and georgia all kept the branches of government "separate and distinct." <SEP> <P1-S0> There are currently about 55,000 wild grizzly bears total located throughout North America, most of which reside in Alaska. <P1-S1> Only about 1,500 grizzlies are left in the lower 48 states of the US. <P1-S2> Of these, about 800 live in Montana. <P1-S3> About 600 more live in Wyoming, in the Yellowstone - Teton area. <P1-S4> There are an estimated 70 -- 100 grizzly bears living in northern and eastern Idaho. <P1-S5> Its original range included much of the Great Plains and the southwestern states, but it has been extirpated in most of those areas. <P1-S6> Combining Canada and the United States, grizzly bears inhabit approximately half the area of their historical range. <SEP> <P2-S0> The Alaska Purchase (Russian: Продажа Аляски, tr. <P2-S1> Prodazha Alyaski) was the United States' acquisition of Alaska from the Russian Empire on March 30, 1867, by a treaty ratified by the United States Senate, and signed by president Andrew Johnson. <SEP> <P3-S0> the vice president of the united states (informally referred to as vpotus, or veep) is a constitutional officer in the legislative branch of the federal government of the united states as the president of the senate under article i, section 3, clause 4, of the united states constitution, as well as the second highest executive branch officer, after the president of the united states. <P3-S1> in accordance with the 25th amendment, he is the highest - ranking official in the presidential line of succession, and is a statutory member of the national security council under the national security act of 1947. <SEP> <P4-S0> Lafayette Curry Baker (October 13, 1826 – July 3, 1868) was a United States investigator and spy, serving the Union Army, during the American Civil War and under Presidents Abraham Lincoln and Andrew Johnson.
