Campbell’s Biology‚ 9e (Reece et al.) Chapter 31 Fungi Though fungal divisions have traditionally been based on modes of sexual reproduction‚ molecular considerations are becoming more important. Consequently‚ no emphasis has been placed on the vagaries of sexual and asexual reproduction among various fungi in this Test Bank. Instead‚ new questions assess students’ abilities to think logically about fungal morphology‚ genetics‚ and ecology. Two new sets of scenario questions deal with the biology

Preparation of Acetylsalicylic Acid Abstract Acetylsalicylic acid was prepared using salicylic acid and acetic anhydride. As a result‚ a white‚ powdery substance was formed (0.1931g‚ percent yield 91.30%) and was defined by melting point (124.5 – 134.5°C) and observation of color change with ferric chloride. Introduction Acetylsalicylic acid (aspirin) is one of the most popular analgesic drugs on the market today. It also acts as an antipyretic and anti-inflammatory drug. Salicylic acid itself

Preparation of Synthetic Banana Oil Introduction: In this lab the synthesis‚ purification‚ and characterization of isoamyl acetate‚ or banana oil‚ was determined. The synthesis was completed by a reversible esterification reaction which required the heating of glacial acetic acid and isoamyl alcohol‚ combined with a sulfuric acid catalyst in hexane. In order to increase the efficiency of the reaction‚ LeChatelier’s Principle is utilized by removing water from the products. As a result‚ the reaction
