1. the legislative branch of government (Congress) examines a proposed bill and can either reject or vote to make it into a law.
2: when Congress votes in favor of making a bill into law, the Executive branch of government ( the president) signs it into law. If the president does not approve of the bill, he/she can veto it, and send recommendations to Congress to amend the bill.
if Congress approves a bill 2/3 or more of both the house and Senate, it shall become a law, and the president cant veto it.
3: The judicial branch of government (the supreme Court) interprets laws and upholds the constitution. When disagreements occur between the legislative and executive branches of government, the judicial branch has the power to resolve the disagreement by interpreting the law in view of existing laws and the consitution.
4: the varying roles of the three branches of government prove a system of checks and balances so that no branch of government can abuse power or authority over the governed.
The Querechos or Apaches.
The Wichitas fought wars with other tribes. They didn't fight over territory, but instead to prove their courage. Some tribes the Wichitas frequently fought and consider their <em>enemies</em> were the Apaches.
During the end of the Spanish rule, the Apaches staged constant attacks against the Spanish missions. But as de 1700s wore on, they found themselves subject to attacking from the fearsome Comanches. Eventually, they entered an on-again, off-again relationship with the Spanish, sometimes warring and attacking, other times <em>allying with the Spanish</em> against the Comanches and other enemies. Those peace efforts with the Spanish resulted in the establishment of Spanish missions.
