It is important to know what your are writing to whom.
emotions should never be used, use proper spelling and punctuation, use full words, avoid using colloquial words/ expressions, avoid using first and second person pronouns, avoid the use of cleche`s.do not write as you would speak, do not start a sentence with a coordinating junction, avoid using the word get.
Newspapers, magazines, journal articles,and business reports are great sources of formal writing.
Coralline algae, sponges, and other organisms contribute is a fact. All the others are opinions
hope this helps:))
