Either a comma or a semi colon can be used, depending on the rest of the sentence.
I do not use a comma before and after that word, therefore you will not see it in any sentence I have written.
Say your sentence aloud. If you find you pause before the word 'therefore', you will probably want to insert a comma. If you do not pause, no comma is required. Use a comma when the sense requires it, not because you have a specific word in your sentence.

No, a comma is not typically used before the word "apparently" at the end of a sentence.
You do not always need to use a comma with the word sobut if you do, it is best to only use the comma before the word. An example is "The travellers faced a long drive home, so they decided to stop at MacDonald's first."
Depending on what the sentence is about you may use a comma before 'called';however, in some instances you may not be allowed to place a comma before the word called.
You do not typically use a comma directly before or after the word "but" when it is used as a conjunction to connect two independent clauses. However, you may use a comma before "but" when it is used to introduce a contrasting element in a sentence.
