Bacterial Morphology Demonica Britt Microbiology DL1 March 23‚ 2013 Abstract This lab was performed to identify and familiarize with a microscope while precisely observing various bacterial shapes and their arrangements in different types of specimens of bacteria. The microscope parts and capabilities were clearly identified and used successfully and the bacteria were clearly illustrated showing the bacterial shapes and arrangements with all the appropriate magnification being utilized.

using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The RBC in unknown solution B appeared to be swollen‚ therefor‚ the tonicity of unknown solution B was hypotonic. Unknown solution C showed no change

The Fluidity of Neuroscience Gender Norms & Racial Bias in the Study of the Modern "Neuroscience" Neuroscience is the scientific study of the nervous system. Traditionally‚ neuroscience has been seen as a branch of biology. However‚ it is currently an interdisciplinary science that collaborates with other fields such as chemistry‚ computer science‚ engineering‚ linguistics‚ mathematics‚ medicine and allied disciplines‚ philosophy‚ physics‚ and psychology. The term neurobiology is usually used

specificity of immunology with the precision of microscopy. There are two types or techniques of immunofluorescence that are direct and indirect immunofluorescence. In direct immunofluorescence‚ specific antibodies are conjugated with fluorescent compounds. The conjugated antiserum is added to tissues and thus fixed to the antigens. Unbound antibodies and non-antibody proteins are removed by washing and the preparation is observed in a fluorescence microscope. Meanwhile‚ indirect immunofluorescence‚ indirect

Lynes) In the 1920’s‚ the maximum magnification of a research microscope was only 2‚000 to 2‚500 X‚ so he did what he’d been trained to do; he designed and built 5 new microscopes with a range of 5‚000 to 50‚000 X. Using his own instruments‚ he was the first person to photograph the heretofore invisible life forms that traveled in and out of view‚ alive and motile. He was known to sit for 48 hours at a time‚ peering into his microscope‚ bringing a specimen into sharp focus. (Nobody had observed what

the microscope. Since the rate of pulsation is easily seen and calculated it’s easy to test the effects of different chemicals on their cardiovascular system. Since it’s known that caffeine increases the blood pressure one might expect that the blackworms under the influence of caffeine will show a grater average of pulsation rate. II. Material and Methods Materials: • High concentrated caffeine • Plastic pipette • 4 blackworms • Microscope • Microscope slide

The mystery powder is living‚ however‚ it is no longer alive. While placing it under a dissecting microscope under a 450x magnification‚ it was easy to come to the conclusion that it was a bug‚ due to the distinguishable body type‚ including a pair of eyes. In biology‚ a list was constructed that had “characteristics of living things.” The list was composed of characteristics such as: movement‚ eating‚ breathing‚ reproduce‚ produce water‚ and have a life cycle‚ to name a few. Because the bug was
