Study Questions: Chapter 28 1.) Archaea and Bacteria are the oldest‚ structurally simplest and most abundant forms of life. 2.) Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.

shocking‚ burning‚ and killing animals is all in a day’s work for vivisectors A vivisector is someone who performs medical research on a live subject. If these atrocious acts were committed outside laboratories‚ they would be felonies. But animals suffer and die every day in laboratories with little or no protection from cruelty. Cruelty involving an innocent animal is a sensitive subject to most of us. In the words of the U.S. Department of Agriculture‚ animals in experimentation are subject to

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic
