Make choppy writing flow. Choppy sentences interrupt the smooth flow of thought and they can be repetitious. Combine overly short sentences with the help of transitional words coordinating conjunctions . and yet but nor or and subordinating conjunctions . unless since because if when . Choppy writing Cytolytic toxins act directly on cell membranes. They disturb the normal physiology of the target cell. They ultimately kill the cell. Cytolytic toxins are not a single group of related chemicals. They are not produced by one class of organism. These toxins are heterogeneous in their chemical structures. They can be obtained from plant and animal sources. They do not share a common mechanism of action. There are several ways for cytolytic toxins to interfere with the normal permeability barrier formed by the cell membrane. See Table 1. Improved Cytolytic toxins act directly on cell membranes by disturbing the normal physiology of the target cell and Coord. Conj. ultimately killing it. These toxins are not a single group of related chemicals produced by one class of organism. Rather transitional word they are very heterogeneous in their chemical structures and Coord. Conj. can be obtained from both plant and animal sources. Consequently transitional word cytolytic toxins do not share a common mechanism of action but Coord. Conj. have several ways as summarized in Table 1 of interfering with the normal permeability barrier of the cell membrane. 4. Use parallel subject headings to reveal logical flow. Technical subject matter sometimes is so dense with terminology and operations that even well-designed paragraphs are difficult to follow. The reader must struggle to work out the natural hierarchy of ideas. Subject headings often help by marking out topical patterns of subordination and parallelism
