The following tests according to the lab manual were performed: gram stain, fermentation tubes, methyl red, vogues proskauer, sulfur, indole, motility and growing it up on MacConkey agar. The gram stain was performed incorrectly the first time. This is because the decolorizer was not on the bacterium slide for long enough, giving a false outcome.

Bread. A common household food item used in pizza, sandwiches, burgers, and more. But when bread sits out too long you start to notice some fuzzy stuff growing on it. This fuzzy stuff is Rhizopus Stolonifer or, more commonly known as, black bread mold. This mold is a member of the of the phylum Zygomycota, which have life cycles that include a zygospore. A zygospore is a resting spore that has zygotes made when the mold is in its sexual phase of its lifecycle. Rhizopus stolonifer reproduced asexually and sexually. This happens when two hyphae come together, from different mating types, and form gametangia. The gametangia the fuses

After finishing the entire lab experiment, I find that those were the only big problems I had. If I were to improve this experiment, though, I would find a good window ledge, buy a tape measure and have a better object to block the experimental seeds from the sun. Other than these factors, I feel this lab went very successfully and that the results were reasonably accurate.

A wide variety of processes had been performed to determine what culture had been acquired in class. My group had acquired culture tube unknown #3. We first isolated the bacteria. In this step we took the broth of the unknown #3 and grew it on an agar plate. The first process that had been performed was discontinuous streaking, and continuous streaking to grow the culture for future use in the lab and to have extra to perform a whole variety of test to determine the unknown. The next experiment that had been performed

He was a hard working student, but not the best. He received a doctorate degree in 1847. He also spent lots of time related to research on tartrate acid. He found different ways to kill many different germs. He found cures for rabies and anthrax and found a way to pasteurize milk. That saved many lives.

Paul Rand was a very artistic designer that knew how to speak through his graphic designs. He is well known for the best graphics representing some of the biggest companies, one of them being IBM. Today his legacy still lives and his graphics speaks for themselves on the side of buildings, television and on automobiles, UPS also being one of his major graphic designs. Rand influenced many other graphic designers , such as: Tom Geismar whom company is known for its work , mostly from Chase and PBS. Paul Rand brought to television what others didnt see nor understand. He taught them that designs could speak to an audience and tell a story that words couldnt. Also, showing them that a unique symbol to represent the company will be a plus for

Germany was aware of its own backwardness, while vigorously develop science and education. With its people’s emphasis on learning and rigorous and unremitting national spirit, Germany has trained a large number of outstanding talents for the second industrial revolution. This is inextricably linked to German government’s emphasis on education and the development of science and technology. Germany’s advances in chemistry, biology and physics provided many conditions for medical research and have made many achievements. Such as Dr. Robert Koch discovered the tuberculosis in 1862, Emil von Behring discovered the diphtheria serum in 1864 and medical scientist like Rudolf Virchow and Konrad Roentgen who all participate in the improvement of public health conditions.

In 1862 he went to Göttingen to study Medicine. His Professor of Anatomy was Jacob Henle and Koch was influenced by Henle’s view, that infectious diseases were caused by living, parasitic organisms.

My prediction is that I will find that roots and shoots have different banding patterns in the gel. “On a dry weight basis, shoots contain more enzyme than roots.” is one source of literature (Giannopolitis and Ries, 1977). Some of the changes that were made in protocol are: the mortar and pestle we used was taken from the refrigerator not the freezer, we used 1.5 ml of cold extraction buffer rather then 0.5 ml, we didn’t leave any wells empty, also the voltage in the electrophoresis chamber was increased so we were able to get our results before class had ended. The material that I used for information and instructions is my Fundamentals of Life Science Laboratory II

In a study conducted by Andrew K. Przybyliski(2014), the author states the correlation between the amount of time children spend playing electronic games each day and the effect on the way children adjust psychologically. The researcher proposes three different hypotheses in which he wants to prove this claim. In his first hypothesis he states that low levels of play, one hour, will enable a child to adjust more easily than other children. While his second hypothesis states that moderate levels of play, one to three hours, leads to both positive and negative adjustment. The final hypothesis states that high levels of play, three or more hours, most likely cause negative effects on the way children adjust.

The scientist I decided to write about is Edward Jenner who lived from 1749-1823. He was born in Berkeley, Gloucestershire, England (The Jenner Institute, 2015). His father was a preacher and died when Edward was five years old, orphaning Edward (Famous Scientists, 2015, Riedel, 2005). He went to school in Wotton-under-Edge and Cirencester (The Jenner Institute, 2015). While he was attending school, his older brother inoculated him for a disease called smallpox when he was only eight years (Adler, 2004, The Jenner Institute, 2015). When Jenner was 14 years old, he studied under a surgeon, Daniel Ludlow, for 7 years where he learned about surgical and medical practice (The Jenner Institute, 2015, Riedel, 2005). In the year 1770 at the age of

He stood against the many mainstream medical practices and theories of his day, in using bloodletting and purging, and in due course also the barbaric treatment and locking up in dungeons of the mentally disturbed (Verlag 2016). “It is no exaggeration to say that he stands out across the entire length of medical history as a colossus, a courageous pioneer, a fearless groundbreaker, an innovator in every aspect of medical theory and practice and, of course a rebel, a troublemaker” (Verlag 2016). 14 years later, he practiced medicine with great popularity until death in Paris 1843 (Britannica 2018). In 1821, he moved to Köthen and served as a physician to Duke Ferinand of Anhalt-Köthen (Dr. Willmar

cerevisiae were obtained and labeled accordingly. These served as the starting point for the experiment. An untainted YPD plate is retrieved and sectioned into three areas and labeled: “A”, “B”, and “C”. A small sample of each strain of yeast is taken and lightly spread onto its own section of the YPD plate. The plate will then be left in the incubator at 30 ° C for 24 hours. In the time preceding time five more media plates are acquired and labeled according to a key that indicates the type of media it is. After the time of incubation the original YPD plate is then replicated on SD+His+Leu, SD+His+Ura, SD+His+Leu+Ura and YPD plates (YPD being the control). Each plate needs to be labeled in the same manner as the first media plate so observations can be correctly made. Each replica place should also be labeled according to which strains are going to be transferred to it. A cylinder shape block, with a compression ring is used along with a precut section of velvet in order to transfer an identical pattern of the yeast on the original plate. All of the plates are reentered into the incubator for 48 hours, then the new growth is observed and

The origin of the discovery of anthrax is debatable among scholars. Robert Koch is accredited with the discovery of anthrax in his 1876 publication of the results of his decade lone experiments. This is the most familiar of the anthrax discovery events to the majority of scientists. The discovery of anthrax as an infectious disease was the first of its kind and supported the germ theory that had been around for centuries. The discovery verified the newfound study of microbiology and sparked the creation of vaccines for microbiological infections. Although Koch is accredited with the discovery of anthrax as a source of microbial infection, anthrax and the diseases that it can cause had been noticed for nearly a century prior to Koch’s discovery. The 18th century discovery and observation of anthrax and its diseases are regarded as just as important as Koch’s final discovery because without the 17th century discovery, Koch would have no foundation to support his experiments.

Started this experiment on February 25th and we gathered all our results on May 3rd 2016. When we started we tested Redbuds in 4 treatments and tested Peaches in 3 treatments. For the Redbuds, we did a control group with nothing but wrapping it with a paper towel and storing it into a Ziploc bag. Then we soaked redbuds in sulfuric acid without promix, and soaked them with sulfuric acid with promix (not moist), and then for the last lot we wrapped redbuds with moist promix. For peaches we also had a control group with just storing them in a Ziploc bag, and for the second lot we placed that seeds in moist promix in a cooler. Finally, for the third lot we soaked the seeds in water for a week and added moist promix and then placed in the cooler. As a result, to this experiment of scarification and stratification we have seen that lot 3 for Redbuds (scarification) germinated 16/40, which is a good amount of germination. For stratification with the peaches only lot 2 germinated 1/20 which was more than the other lots.
