Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

The earliest known reports of plastic surgery date back to 600 BC when a Hindu surgeon reassembled a nose using materials from a cheek. Soon after‚ plastic surgery became common through ritual practices of cutting off enemies’ noses and lips. According to The American Society for Aesthetic Plastic Surgery‚ Americans spent more than twelve billion dollars on surgical and nonsurgical procedures in 2014. With plastic surgery trending‚ society debates whether it is a victory for the science community

Hospital Hygiene As Hospital Director‚ many actions need to be taken when it comes to keeping this hospital safe and free from bacteria as possible. Many infection control measure should be taken‚ and it is not an issue that should be taken take lightly. Many things will be implemented into the building of this hospital to prevent and reduce the risk of Hospital Acquired Infections (HAIs). One measure that will be taken to prevent HAIs is installing copper‚ bronze‚ and brass fixtures throughout

stop transmission of the transient micro-organisms when in direct contact with patients (NHS‚ 2009). Alcohol-based hand rubs or gels should not be used alone when infection is present as this alone will not kill the spores for infection such as clostridium difficile. After washing hands must be dried properly as failure to do this can increase the transfer of bacteria (Nottingham University Hospitals‚ 2011). Hygienic hygiene not only removes transient microorganisms but also reduces resident microorganisms

once every 20 minutes! So let’s say if you have 1 bacterium at 9am on Monday‚ by noon you will have 512 and 8 by 4pm you will have over 2 million and by the time you go to bed (8pm) you will have nearly 9 thousand million! Bad bacteria like the Clostridium family‚ of botulism fame‚ live in our guts and dine on our Western diets of high fat‚ high sugar and processed foods. These bacteria can produce toxins that are released into the bloodstream and could affect the brain in a bad way. Microbes also

5.1 MANUFACTURING PROCESSES: Acetone is produced directly or indirectly by propylene. Early processes for the manufacture of acetone were based on the thermal decomposition of calcium acetate or the carbohydrate fermentation of corn starch or molasses. The ready availability of propylene in the 1960s led to routes based on the dehydrogenation of isopropyl alcohol or cumene peroxidation. (1) By Cumene Oxidation (Hock Process). Propene is added to benzene [71-43-2] to form cumene [98-82-8]‚ which
