Both articles seem to have well written paragraphs that flow together. The paragraphs begin with a topic sentence and then add detail and end with a closing. The difference is in the blending of the paragraphs when looked at as a whole. The research article seems to be more abrupt at getting directly into the subject matter and the paragraphs flow together so that the topic sentence of one picks up from the end of the preceding paragraph. Taken alone, one paragraph may have less of a standard topic sentence, but the research article is meant to flow from one paragraph to another and when read this way makes sense. The review article takes more liberties in the time it takes to explain something and has paragraphs that can stand independently more often. The review does not have the same limits to cohesively represent something, like an experiment, which is what the research article has to do. The review can therefore take more time in explaining details that can stand as independent paragraphs. The separate details make separate paragraphs and these inform a more layman reader.

Many sentences start with
Many sentences start with "The" which is not a huge problem on its own. However, three setneces in a row start with "The review article." I would suggest restructuring these in such a way to avoid repeats and to expierment with sentence transitions.
While we know what you're
While we know what you're talking about, it's good to give a topic sentence so readers have some context. I would also give a closing sentence that summarizes the ideas your addressed in your paragraph. Overall, it looks good!
