A. Fermentation Lab- The basic process Prepared 3 beakers with contents listed below. ( a. Beaker 1: glucose only b. Beaker 2: Starch only c. Beaker 3: Starch + amylase). Poured contents of each beaker into its respective fermentation tube‚ ensuring the tail portion of the tube was filled with liquid. Placed tubes in an incubator at 37 degrees‚ measuring distance between tip of tube tail to fluid level at 20‚ 40‚ and 60 minute intervals. Calculated gas volume using this distance along with radius

5PY017 Pharmaceutical Microbiology Evaluation of antimicrobial effectiveness of disinfectants Abstract A control experiment was performed to rule out the effects of the medium and neutralizer to allow us to see the effect of the disinfectant on the four organisms within a 5 minute range. The bacterial suspension used for paired at different concentration data was Staphylococcus Aureus for which gave good results when the reduction factor value of 1.20x106 ml-1 was obtained for the organism

1. Bedbugs have been evolving in the United States since the 1940s and 50s. (1) Due to genetic mutations after World War II a widespread of pesticides known to be DDT was used. The genetic variation makes them resistant to the pesticides. (2) These DDT pesticides were used on the bedbug population‚ making them resistant to the pesticide. This illustrates natural selection because those resistant with the pesticide survive best. Which is heritable to their population with the resistant pesticide offspring

Crystal‚ D. (2004). The Stories of English. New York: The Overlook Press. David Crystal’s book immediately grabs your attention through the characters placed around the table. The images give the illusion of historical men drinking wine‚ smoking pipes‚ and discusses important matters of the time. The caption bubbles are the foreshadowing of what’s to come. The introduction states that there are actually two introductions‚ due to the two stories the book investigates: “Standard English “and “Real

A cycle is defined as any complete round or series of occurrences that repeats or is repeated in the same order and at the same intervals. The natural existence of cycles is highly important without cycles resources would run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each

Microorganisms: * Small living organisms; there are 3 types * Bacteria – ecoli‚ salmonella * Fungi – mushrooms‚ athletes foot * Virus – influenza (flu)‚ HIV * When they enter our body‚ they multiply and release toxins / harmful chemicals into our blood * They duplicate every 20 minutes * Physical barriers: eyelashes prevent MO’s from entering through our eyes‚ nasal hairs reduce them‚ skin is a barrier to them (although they can enter through cuts)‚ chemicals in tears

CELLS All living things are made of cells‚ and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms‚ and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (the bacteria) and those of the other four kingdoms (animals‚ plants‚ fungi and protoctista)‚ which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells‚ and do not have a nucleus. Prokaryote

Jordan Wong Schiefer Acc Bio Block 6 11/15/12 Unit 4 Biochemistry relates to all things living because biochemistry makes up everything living. The atoms that make up the cells within our body are a part of biochemistry. There is carbon in every living thing and carbon based molecules are a part of biochemistry. Unit 4 describes the biochemistry in all living things. It explains the atomic structure and ions‚ properties of water and pH‚ organic molecules‚ chemical reactions and enzymes.

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important
