Please help! What elements of continuity and change appear during the time period of 1803-1848 in terms of westward expansion? (this question isn't multiple choice it is just like a 3-5 sentence q/a.)

hello,

i'm not so sure but i hope this in anyway.

the president of russia is head of state, and of a multi-party system with executive power exercised by the government, headed by the prime minister, who is appointed by the president with the parliament's approval.

hope this : )
