If sodium chloride is added to a solution with Saccharomyces cerevisiae‚ then sodium chloride should hinder the growth and reproduction of those cells because the salt concentrations will limit the overall efficiency of the cell’s reproductive processes as well as decrease overall colony size. In our experiment‚ we plan to note the effects of salt on S. cerevisiae by both spot plating to note overall cell colony size and the number of total cells and through the use of electro photometry to also

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

Labs and Diagnostics Colonoscopy This test allows direct visualization of the small bowel‚ rectum‚ and colon. It is recommended for patients who have experienced fecal occult blood or obvious blood in the stool. It is also recommended for patients who have experienced a change in bowel habits or are experiencing abdominal pain. In patients who have had colorectal cancer‚ polyposis‚ or inflammatory bowel disease it is used to observe for continued progression of their condition. During the procedure

couple of key things about lab safety and procedure during this experiment. While working with the hot plates‚ I learned to pay a lot of attention to whether or not the hot plate was plugged in or turned on‚ as well as whether or not the wax was getting too hot. Measuring each substance into the cup was an important experience because it taught me to be deliberate and careful when measuring so as to not waste materials‚ making sure we did not have to start over. While this lab is a good starting point

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate
