What are bacteria? Bacteria are very different from viruses. First of all‚ bacteria are much larger in size. The largest virus is only as big as the very smallest bacterium (singular for bacteria). But bacteria are still microscopic and cannot be seen with the naked eye. They are so small that the sizes of bacteria are measured in micrometers (10‚000 micrometers = 1 centimeter). By comparison‚ the head of a pin is about 1000 micrometers wide. Though more complex than a virus‚ the structure of a

Abstract: Bacteria consists of a large domain of prokaryotic microorganism in which can fight of antibiotics allowing the bacteria to become antibiotic resistant. In this lab report‚ we discover the most effective disinfectant that would work best in killing the harmful bacterial strain‚ Bacillus subtilis. KB testing or disc diffusion antibiotic sensitivity testing is measured through the diameter in millimeters to find how resistant the antibiotic to the bacteria. The hypothesis of Windex fell correctly

murder may require a lesser intent. [3] When a defendant commits murder that is a specific intent crime because the defendant knew that there was a very high risk of death or grievous bodily injury. [4] In conclusion the difference between general and specific intent is the defendants’ intentions before committing the crime. If the defendant was reckless and negligent then it will be a general intent crime because he didn’t plan the outcome before committing the crime but he still committed

Livja Koka Anaerobic Bacteria In this experiment the purpose is to seek understanding between an organism and its use of oxygen. Oxygen is a very important part of the organisms’ survival. Oxygen has a tendency to form very reactive by-products inside a cell. These by-products create havoc by reacting with protein and DNA‚ thus inactivating them. Cells that are able to live in the presence of oxygen have evolved enzymes to cope with H2O2 and O2- and thus are not inhibited by O2. Also many anaerobes

When he returned‚ he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him‚ a spore of a rare variant called Penicillium notatum had drifted in from

Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some of the earliest forms of life. In this chapter‚ we will learn how bacterial groups are differentiated from each other and how important bacteria are in

The Fear of The Unknown The short stories of Ben Loory‚ Stories for Nighttime and Some for the Day‚ exhibit numerous postmodern qualities through literary context‚ language and themes. One of these reoccurring themes within the collection is the concept of fear of the unknown. Three stories exemplary of this theme are “The Magic Pig‚” “The Fish in the Teapot‚” and “The Snake in the Throat.” In every one of these stories chosen there is an appearance of an object. One character is tortured by the

Themes of W.H. Auden’s "The Unknown Citizen" Conformity and Anonymity in the Modern World "Social Security Number? Birth date? Nine digit telephone number starting with area code? Mother’s Maiden Name?" In many ways‚ we are simply faceless numbers to modern society‚ not individuals with feelings and emotions and dreams. W.H. Auden‚ a well-known English poet and dramatist‚ discusses this important theme in his poem "An Unknown Soldier." Auden‚ being a modernist‚ is concerned with this modern idea
