different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain or lose mass. If the dialysis tubing is submerged in different substance than what is in the tubing then

the concentration of hydrogen peroxide the faster the reaction will occur and the more foam will be produced. Aim: The aim of this investigation is to determine how the concentration of hydrogen peroxide effects the intensity of the reaction. Variables: Independent- The concentration of hydrogen peroxide. Dependant - The intensity of the reaction. Constants – The temperature‚ the amount of liver‚ pH level‚ test time‚ Materials: Solutions of hydrogen peroxide varying in concentration 1‚2‚4

and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces CO2‚ which in high concentrations is harmful

Effect of Substrate Choice On Growth Of Mealworms Abstract: The experiment is designed to show which substrate A or B will better nourish a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth

Minimum Inhibitory Concentration (MIC) is a way to measure the sensitivity of microbes to antibiotics or antifungals (antimicrobials). Organisms are tested for growth in various concentrations of antibiotic. This allows microbiologists to see which concentration (MIC) of antimicrobial will be effective against the pathogen. It also used for determining treatment for patients suffering from infections such as pneumonia‚ meningitis‚ endocarditis or osteomyelitis or managing the treatment of high-risk

A protein standard curve was generated by using the protein standard (1 ampule) measurement at 595 nm. Standard curve was prepared as shown in Table 4. Bovine serum albumin (BSA) was diluted with distilled water. The absorbance of each sample were measured using spectrophotometer at 595nm. Standard protein curve was plotted according to the concentration of protein where the x-axis and y-axis represent protein standard concentration and absorbance (595 nm) respectively. 3.10.2 Protein Determination

Kothapalli Mrs. Manning Honors Biology 30 November 2012 TITLE: The Reaction Rate of Catalase in Various Concentrations of Hydrogen Peroxide QUESTION: How long does the catalase take to float to the top of a cup filled with different amounts of hydrogen peroxide concentration? PREDICTION: A prediction that can be made for this experiment is that the higher the concentration‚ the faster time it takes the catalase to react with the solution. As the concentration increases from 1% to 100%‚
