Select the procedure suitable for demonstrating secretory granules in a carcinoid tumor: A. Wilder reticulum B. PAS-aniline blue C. Snook D. Sevier-Munger D. Sevier-Munger The Sevier-Munger technique is an excellent argyrophil procedure for demonstrating carcinoid tumors. It is similar to, but shorter than, the Grimelius. In Bodian's method for nerve fibers and neurofibrils, Protargol impregnates both neurofribrils and connective tissue. Subsequently, connective tissue is rendere...

Chemistry II Final Exam Study Guide Test. Which of the following is not a solution? Select the correct answer below: air an alloy of zinc and copper a mixture of oil and water potassium permanganate dissolved in water - CORRECT ANSWER a mixture of oil and water Oil and water are immiscible liquids, meaning they will not form a homogeneous mixture when added together. Therefore, a mixture of oil and water will not be a solution. Air is a gaseous solution: a homogeneous mixture of nitro...
