Compare The Size And Number Of Coacervates Lab Report

1781 Words8 Pages

Aim

The aim of this experiment is to test the size and number difference of coacervates when the concentration of gelatin and gum arabic are changed.

Research Question

How can changing the percentage of gelatin and gum arabic from 1% to 5% affect the size and number of coacervates.

Research Hypothesis

If gelatin and gum arabic are combined in an acidic environment, and the concentration is changed from 1% to 5%, the coacervates will increase in number and size.

Independent Variable

The independent variable in this experiment is the different concentrations of gelatin to gum arabic. (the changing percent)

Dependent Variable

The dependent variable in this experiment is the size and number of coacervates formed from the chemical solution.

Constant

The constants in this experiment are that the …show more content…

The null hypothesis states that there is not a significant difference in the sizes from the baseline to trial 2. The mean number of coacervates for the baseline is 32. The mean number of coacervates in trial 2 was 26.67. The t- test supports the null hypothesis. A larger t-value means a larger variance in the means of the data, a smaller t-value means less difference between the means. The T table value is 1.0371. This number’s close proximity to 0 concludes that there is no significant difference in the number of coacervates. o we reject the alternative hypothesis, and accept the null.
The strengths of this experiment are that there was the ability to test size and number in the same process. The limitations of the experiment are the accuracy of the measurements and the precision of the concentration of gelatin and gum arabic. If this experiment were replicated, an improvement could be measuring the amount of gelatin and gum arabic precisely. Also more than 1 slide could be made with the same concentration, to ensure accurate

Serum 2216 Lab Report

592 Words | 3 Pages

The investigation was carried out to identify the presence or absence of biological molecules in serum 2216. If the concentration in each test tube of the dilutions carried out will be more concentrated then the concentration of the test tube before it, then the color will be at an equal concentration with the other dilutions performed. The hypothesis was wrong because of the difference in concentrations due to the different measurements within the dilutions done. The test for starch was to add a drop of iodine solution to the pipette in the spotting tile. A reducing sugar solutions is add inside a test tube with 3 drops to then add 3 drops of benedicts and plane in a water bath.

Independent Variable amount of substrate (sucrose) present 3. Controlled Variables temperature, pH, sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. I believe glucose and fructose was used as an indicator because they are what produces sucrose and sucrose creates more sucrase activity.

Gummy Bear Lab Report

The purpose of this experiment was to observe the relationship between different solutions and their effect on the mass and length of a gummy bear. Gummy bears with the same relative size and colour were placed in 50 mL beakers with the same amount of their designated liquid. The different solutions studied were water, oil, vinegar, a simple sugar solution, and rubbing alcohol. In the end, based on the observations made, the majority of the hypotheses created were not proven to be correct.

The errors that could have occurred in this experiment include miscalculations of determining the mass, averages, and percentages of each brand of gum. In addition, chewing the gum for too long is another error that also could have happened. Furthermore, weighing the gum and wrapper incorrectly is also another error.

Mitochondrial Activity Lab Report

First, it was hypothesized that test tube "A", the control, would not show any red concentration, test tube "B" which contains supernatant II would show the most red concentration and test tube "C" which contains sediment II would only show a little red concentration. The second hypothesis states that the raw corn kernels would have mitochondrial activity while the boiled corn kernels would not. The last hypothesis interprets that the "gunk" and sediment I will both contain starch granules. It was only expected to find mitochondrial activity in Supernatant II. Unfortunately, after performing this experiment, we were not able to support this hypothesis and come up with a conclusion.

What is the effect of surface area to volume ratio on the rate of diffusion of the colour from the agar jelly cube? INTRODUCTION: Diffusion is the movement of spreading particles from high concentration to low concentration in an environment such as a cell. This major procedure is used in cells to source them with nutrients, water, oxygen, and to transport unwanted wastes such as carbon dioxide out of the cell or to different cellular organelles.

Introduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).
