goldfish’s metabolic process at two different temperatures a chamber and Logger-Lite‚ computer software‚ were used during this lab. However‚ only data from lab section 1F was analyzed for this report. The goal was to determine if the goldfish’s metabolic rates‚ as measured by oxygen consumption‚ will increase when the water temperature is moderately warm. Alternatively‚ the metabolic rates of goldfish‚ as measured by oxygen consumption‚ will not differ between warm and ambient temperatures. Materials and

Headline: Abnormal Liver Enzymes: What Does It Mean? Keywords: Liver‚ increase‚ enzymes‚ symptoms‚ test Page Description: Elevated liver enzyme is a condition in which there is an increase in the leakage of chemicals i.e. liver enzymes through liver cells. This hike leads to symptoms of various health problems. Blood test can be used in determining the associated causes and symptoms. Text: { What is meant by Elevated Liver Enzymes? Elevated liver enzymes are a common problem. Inflammation or

The total protein content was estimated as proposed by Lowry et al. A bovine serum albumin stock solution (1mg/ml) was prepared in sodium hydroxide (1N). Five different concentrations (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1 ml) of the prepared solution were taken in different test tubes. In another set of test tubes‚ 0.1 and 0.2 ml of the extract were taken. In each test tube‚ the volume was made up to 1 ml‚ followed by addition of the prepared alkaline solution (5 ml) at room temperature. The solutions were left

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

Abstract For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof‚ to demonstrate the necessity of light and chlorophyll in the process of photosynthesis. Background Photosynthesis occurs in organisms which contain chlorophyll. It’s a process that involves the chloroplasts to synthesize glucose

Size‚ Temperature‚ Concentration‚ and a Catalyst on Reaction Rate Introduction: Chemical reactions can be affected by a number of different factors. Particle size‚ temperature‚ concentration of a solution‚ and catalysts play a big role in the rate of reaction‚ they determine how fast a reaction will occur. According to the collision theory‚ the rate of reaction depends on the frequency of effective collisions between particles. Every reaction is different in that they all require different conditions

Abstract The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver‚ blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed‚ ammonium sulfate was added to the supernatant‚ chilled and then spun for a second time. Next‚ 20 mL of water is added to the pellet‚ stirred and the volume was recorded. The teacher calculated the total mass of liver to be 10.098g. Lastly a spectronic

According to the results in this lab Jell-O must contain protein due to the fact that the meat tenderizer was able to break down the Jell-O much the same as it would break down the proteins in meat. 5. Did the amount of meat tenderizer give different results? The amount of meat tenderizer did give different results‚ cup â»2 with the least amount of tenderizer did not break down as much as the cup â»3 with the most tenderizer. Conclusion According to this lab it demonstrated that Jell-O does
