Leah Romero 10/30/2017 Conclusion Lab 3 Chem 102L In lab 3, fundamentals of chromatography, the purpose was to examine how components of mixtures can be separated by taking advantage of different in physical properties. A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes. Chromatograms where made for the known FD&C and for the three Kool-Aid samples. The retention factor for each dye was calculated.
Removing a sample of kidney tissue for testing. Your doctor may recommend a kidney biopsy to remove a sample of kidney tissue. Kidney biopsy is often done with local anesthesia using a long, thin needle that's inserted through your skin and into your kidney. The biopsy sample is sent to a lab for testing to help determine what's causing your kidney problem. There are many stages of Chronic kidney failure.
The Aim of Enzyme Catalase Experiment is making a series of experiments involving the enzyme Catalase which has been performed in order to determine some of the enzyme 's properties. The enzyme found in different conditions which its specific reaction rate. Variation in enzyme concentration, variation in pH, variation in temperature, and the effect of different concentrations of inhibitors were all tested. The enzyme concentration increased the reaction rate. An optimum pH and temperature were found for the enzyme, outside of this optimum the reaction rate would be lower.
Enzyme assays are performed to serve two different purposes: (i) To identify a special enzyme by proving its presence or absence in a distinct specimen. (ii) To determine the amount of the enzyme in the sample by monitoring the disappearance of substrate or appearance of product. Enzymes speed up reaction rate by decreasing the activation energy required to start the reaction. Activation energy is the energy required to break certain bonds in the substrate so that other bonds can form. The formation of these new bonds results in the formation of the product by measuring the changes in absorbance due to the substrate (starch) being changed into product by the amylase enzyme.
Unless one exercises for a period of time exceeding four hours, electrolyte losses won’t be high enough to affect health or performance and can instead be simply replaced through everyday meals (Smolin). Sports drinks aren’t required in order to have a proper workout, but if for those still searching to replace electrolytes or who are working out for extended periods of time, there are many other, healthier
Thus, any amount of solute within the water will affect the flow of osmosis and the mass of any plant. Although no physical changes happened, that could be seen, ten minutes after placing the potato strips in the saline solutions, it was evident that the more water the beaker had, the more the potato strip weighed. It was also found that the more concentrated the saline solution, the less the potato strip weighed. laboratory, while the potato strips were in their beakers, we had not noticed any changes. Source of
It was also to see how you can identify which biomolecules are present in a substance or a food. I think we achieved the purpose of this experiment and fulfilled what it intended us to do. As we come to the conclusion, I have learned that my hypothesis is indeed correct and there was glucose,starch, and proteins present in the unknown substance. My lab group personally had no idea what the substance was before or after the experiment took place, because glucose, starch, and proteins are present in many other things so learning that these molecules were present didn’t really help us find out what the substance
Altovis consists of a proprietary blend of natural, premium ingredients that work in tandem to help support safe, long-lasting energy. In fact, for most people, one tablet of Altovis in the morning keeps them energized all day. Q: Is Altovis safe?A: Yes. Altovis contains no ephedra, so it doesn’t come with the risks associated with those products. However, if you have a heart condition, high blood pressure, nervous condition, or medical concern, consult your doctor before taking Altovis.
The researchers found that the results for the Berg Balance Scale and the Unified Parkinson’s Disease Rating Scale scores were different for land and aquatic therapy. Only the participants in the aquatic therapy group showed improvement in the Berg Balance Scale and Unified Parkinson’s Disease Rating Scale scores, therefore, the land therapy group did not show critical changes to their scale scores. However, there are some variables that were also unaffected after participating in the 4 week program from both land and aquatic therapy groups. The results showed that there wasn’t a significant change in gait velocity, step amplitude, turn time, cadence, and the duration to complete the timed up and go
You must first test the pH level of the amylase and starch solution using pH test strips, so that the experiment may be fair m. Then measure 3cm3 of amylase solution using the measuring cylinder, the pour it into the test tubes labeled A1-A5 n. Do the same for the starch solution but pour into the test tubes labeled S1-S5 o. Put test tubes A1 and S1 into the beaker labeled “cold water” p. Put test tubes A2 and S2 into the beaker labeled “normal water” q. Put test tubes A3 and S3 into the beaker labeled “warm water” r. Put test tubes A4 and S4 into the beaker labeled “very warm water” s. Put test tubes A5 and S5 into the beaker labeled “hot water” t. Mix the amylase solution with the starch solution when both are at the same temperature in each beakers (pour the amylase solution into the starch solution) u. Quickly add 3 drops of iodine solution into all 5 mixed amylase and starch solutions, while starting the stopwatch for each (should be 5 separate
Week two has been a little more challenging versus week one. I was tempted with sweet tea several times which has made it more difficult. I truly expected it to be easier because I thought after the first week my body would start to adapt without the caffeine from sweet tea. This is not how I expected the assignment to go. I honestly thought I would not have any issues or have any withdrawal symptoms.
A few studies reported no critical contrasts in either the physiological or cognitive execution of people who have and have not devoured caffeinated beverages. Examination has gone for deciding the behavioral impacts that caffeinated beverages have on shoppers, particularly, on their disposition, fixation, response time, readiness, continuance, physical execution, and danger taking. The cognitive and physiological impacts after the utilization of a caffeinated drink in correlation to a placebo brought about fundamentally enhanced execution on both auxiliary memory and rate of consideration (Scholey and Kennedy
Biopsy- To remove a tiny piece of kidney for evaluation. What kind of kidney damage is happening? Urine output measurements- The amount of urine you excrete in a day may help your doctor determine the cause of your kidney failure Chest XRAY- This will show the size of the heart and whether there is fluid build-up around the heart and lungs. Echocardiogram- This will show a graphic outline of the hearts movement. Doppler Ultrasound- To evaluate blood flow across the hearts
A urinalysis is done for multiple reasons that include checking for disease, in the treatment of particular diseases, as part of a routine physical examination. There are 16 components that are checked during this test. Urine is analysed in two way either microscopic or macroscopic. Microscopic is taking a sample and placed on a slide and examined under a microscope. A Macroscopic analysis is done by making visual determination of color and clarity.
This includes running the blood the test the antibodies against proteins found on the Lyme disease bacteria. A spinal tap is also performed for patients that experience nervous system problems. This test also looks for antibodies that are against the Lyme disease Bacteria.
