Bacterial Growth Lab Report
Introduction:
Bacteria need specific living conditions to survive. The ideal conditions for bacterial growth is a warm, dark, and damp environment. This provides the maximum effectiveness for bacterial growth. The areas in our school that contain the most bacteria would be the water fountains because the bacteria from our mouths drop off on to it when we drink from it, and because water fountains are not regularly washed in comparison to weight equipment. Water fountains also provide a warm damp place for the bacteria to live and reproduce. Bacteria use cellular respiration to get energy for reproduction, and other activities. The chemical formula for cellular respiration is C₆H₁₂O₆ + O₂ → CO₂ + H₂O + ATP (or energy). For cellular respiration

The amounts of bacteria on my experimental side were far less than the amount of bacteria on my constant side. In my case, quantitative data can be used to support it even further as it proves that the amount of bacteria on my unaltered, control side of the petri dish was much more than the changed, experimental side of the petri dish. You could also argue that qualitative data could help support it because you can visually see the difference that the Hand Sanitizer made in killing the bacteria. Unfortunately, since I did not do the experiment myself, I cannot make any comment on any possible errors in my experiment. Although if I had to guess, I would guess that for most experiments, the most common error would be failing to keep the constants the same. For example, collecting the bacteria at different times. All pie charts for all students should all be similar because the data was collected and brought together so every group had access to every other group’s data. This means that there should be a consistency within other scientists works. According to our class’s table, the areas that contained the most bacteria would be located on an individual’s hand. This is probably in part because throughout our day, we touch a lot of objects consistently which can rid our hands full of bacteria. The cleaner that seemed to prove most effective seems to be the Hand Sanitizer. This is most likely because Hand Sanitizer was the most used cleaner within all of the

    In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is a fermenter they will use the sugars to make ATP. If the bacteria is a fermenter of lactose/sucrose the EMB plate we used will “clearly differentiate between the colonies of lactose fermenting and non-fermenting microbes. In the same medium sucrose was also included to differentiate between coliforms that were able to ferment sucrose more rapidly than those that were unable to ferment sucrose” (Cheeptham & Lal, 2007).…

    To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2. Basically, cellular respiration is a metabolic process that releases energy from organic compounds (such as C6H12O6) by metabolic chemical oxidation in the mitochondria within each cell. Proteins, carbohydrates, and fats can all be broken down into fuel for the cell but cellular respiration is usually correlated with glucose. Cellular respiration also requires O2 to carry out its pathway, as oxygen will act as a final electron acceptor. So, the final equation that can be represented for Cellular Respiration is: C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + heat.…

    Bacteria are organisms that are extremely copious upon this planet. They are tiny and most are single celled organisms that can survive in just about any environment. Anywhere from plants to the human body is where these organisms can be discovered. Some of the strangest places that support bacterial life include places that have extremes of temperature. These bacteria are also very strange, much different from bacteria found living in and around humans. For example bacteria that live in extreme cold, like the North Pole, use methane as their substrates; and the ones that live in the deep sea use hydrogen sulphide. While most bacteria can live without oxygen (anaerobic bacteria) or whether they are aerobic bacteria that require oxygen. These particular bacteria use carbon-based sugars as main energy source. Even with so much diversity among bacteria, the most interesting part is how they communicate. Cell communication is a central mechanism in bacteria cells because it provides examples of parasitism relationship among different organisms such as S. aureus. It gives a means to control infections through a complex mechanism which is found in Pseudomonas aeruginosa. This touches on some variety of processes, including genetic transfer, antibiotic production growth and pathogenesis.…

    On June 28, 2010, the Supreme Court issued its second major ruling on gun rights in three years, ensuring our federally protected right to keep and bear arms in all 50 states. The ruling states that the right to "keep and bear arms" is incorporated by the Due Process Clause of the Fourteenth Amendment and applies to the states. No longer will State or local governments be allowed to ban most Americans from owning most types of handguns. The ruling effectively strikes down Chicago's handgun ban, not unlike the Washington D.C. law that was already ruled to be unconstitutional by the Supreme Court two years ago in D.C. v. Heller. Gun Rights Advocates hailed the decision across the Country as a major victory before the "conservative" majority…

    I checked the petri dishes daily. During the first three days I saw no results whatsoever. However on the fourth day I finally saw some results. On petri dish #1 there was two tiny white dots. On petri dish #2, I saw 3 tiny dots. On petri dish #3 I saw a big white dot. Each day that I noticed new observation, I would record them on my data table. The petri dishes seemed to grow at about the same rate. However, during the first week petri dish #2 seemed to grow bacteria at a faster rate than the others.…

    When you think of children, what was the first thing that comes to mind? Reckless? Young? Naïve? Gullible? Into the Wild, by Jon Krakauer, is a book written about an extraordinary but childlike man who set out on a quest, looking for an adventure of being surrounded by nature. Chris McCandless, who the book is based off of, was a man of wonder. No one was ever certain about what he thought, how he felt, or why he went on this suicide journey. Was it because of his childlike recklessness? Or was it something deeper? Chris McCandless was reckless and along with that came passion, loneliness, and despair. So, can we really judge him when he made the decision to live in the most wild parts of the Alaskan state?…

    Merchant of Venice

    Throughout the centuries peoples’ views about what a true friendship is have changed and morphed into different things over the years. At one point in time a friend was someone who would do anything for you, at another a friend was a shoulder to cry on, or a person to gossip with about the latest news. At another time a friend was just someone who you could play racquetball or golf with after work. Most people have similar views on what a true friend is. That view is that a true friend is someone who is always there for you and a person you enjoy spending time with. In The Merchant of Venice, Shakespeare shows the reader; through the characters of Bassanio and Antonio, what the true definition of a friendship really is. The definition of friendship from the Merriam-Webster Online Dictionary is ‘the state of being friends’. Antonio and Bassanio have a friendship throughout the play that is similar to this definition and the perceived definition most people have.…
