Answer:
In parliamentary systems:
- After each general election, the victorious majority party -or a majority coalition - chooses the head of government (usually a prime minister);
- members of the opposition can ask for a confidence vote; in some circumstances defined by local constitutions or laws, if a cabinet fails to win it, it must resign, or even new general elections are called;
- in many countries, bills turn into law just through the vote of parliament and the PM´s signature and its publication in official state gazzettes;
- the head of government can call elections in circumstances defined by the constitution or the law (Great Britain).
In presidential systems:
- In most countries, presidents are elected by direct suffrage , directly by the people, not by the parliament; France and the United States are examples. Germany is an exception: the president is elected by parliament;
- in some countries, under circumstances defined by the constitution or the laws, the president can dissolve parliament and call new elections;
- in presidential systems, the president is the head of state;
- in some countries, the president appoints the prime minister and may fire him, too;
- a president´s signature is required so that a bill aproved by parliament becomes law in some countries;
