It depends upon the context. If "but" is being used as a conjunction to link two complete clauses (complete clause meaning containing both subject and verb), it would be preceded by a comma to avoid violating the run-on sentence rule.
Examples:
I like grapes, but I don't like raisins.
I like grapes but not raisins.
In the second example, no comma is needed because the subject is shared by both verbs.
no
No

Not necessarily. There is no word in English that requires a comma.

yes
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.
No, a comma does not go before the word 'in'.
Yes, you can use a comma before the word "but" when it connects two independent clauses. For example: "I wanted to go to the store, but it started raining."
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.
