a dolphin has a large well developed brain

Well-developed paragraphs generally support their topic sentences with evidence, examples, analysis, and explanations. This helps to provide a clear and comprehensive explanation of the main idea presented in the topic sentence. Supporting details help to strengthen the argument or point being made and provide a deeper understanding of the subject matter.

You should hyphenate well nourished and well developed IF followed by a noun - i.e., "well-nourished and well-developed man" or "well-nourished and well-developed patient". If the noun is before these, then you would not hyphenate - i.e., "The patient is well nourished and well developed". This would also be true for the following: "well-healed scar" or "the scar is well healed". Answer provided by a medical transcriptionist with 18 years experience.

A well-developed paragraph has a thesis, an introduction, a body and a conclusion.
