undergraduate readers in diverse areas, including the biological sciences, the allied health sciences, agriculture, environmental science, nutrition, pharmacy, and various pre-professional programs. The Ninth Edition features a new, four-color design and a dramatically new art program. Many of the illustrations have been re-rendered in a modern, realistic, three-dimensional style, and detailed, colorful photomicrographs that were once grouped together in a color insert are now integrated throughout the exercises. Experiments have been refined throughout, and a new exercise on parasitic helminths readers with valuable practice in microscopic examination and observation.
