It really depends on what the rest of the sentence is. For example, it is correct to say, "I don't know who will be there." In that case, there is no comma before "who". It is also correct to say, "My new neighbors, who have not spoken to me yet, keep letting their dog come into my yard and dig holes." That example does contain a comma before "who".
It is usually appropriate to place a comma before "but." One should not use a comma after "but."
A comma before "and" depends on the context. Use a comma before "and" in a list of items (e.g., red, blue, and green). However, do not use a comma before "and" when it connects two independent clauses unless it is needed for clarity or to avoid confusion.
a comma should always precede but. Especially if it is joining a compound sentence. For example,Michael is tall, but Shawn is taller.I want to go to school, but I have to do my homework.
No, a comma is not typically used before the word "apparently" at the end of a sentence.
Maybe. Maybe not. Sometimes. Othertimes not. Whether the use of a comma is or is not appropriate depends on the context.
no
It is usually appropriate to place a comma before "but." One should not use a comma after "but."
In a company name such as "ABC Corp," do not use a comma. However, use a comma in the formulation, "ABC, Inc."
No of course not!only when you have run on sentences.

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

Not necessarily. It depends on the context. If you think in terms of placing a comma after a word, rather than before one, it might be helpful.
