Identification of Macromolecules Introduction The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Briefly, the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy, information and much more. Most foods are known to be combinations of …
To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials …
Differentiating Between Prokaryotic and Eukaryotic Cells, Distinguish Among Plant, Animal, and Protist Cells, and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells, prokaryotes and eukaryotes. Prokaryotes, such as bacteria, lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of …
Purpose: To see how fast organisms and materials decay under certain conditions. Procedure: We gathered 4 2-liter plastic pop bottles and cut them to assemble the drawing below. Near the bottom we placed a siv to let juices drain through into the bottom 2-liter. Then we stacked materials and organisms on top of each other …
CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed …
The oxygen can be observed as bubbles comic Eng from the reaction site. Catalane is found in many living tissues of organisms, including chicken liver. T he purpose of this experiment is to determine what changes in pH, temperature, and enzyme co concentration have on the rate catalane works to break down hydrogen peroxide. If …
This report presents the reason why the ocean does not freeze In the winter. Since the ocean consists of salt water, an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition …
Abstract This experiment made use of the Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis technique to plot a curve displaying the electrophoretic mobilities of 7 proteins against the known molecular weights. Another sample was also run in the SDS-PAGE but with an unknown protein sample. Two proteins were found in the sample and their electrophoretic mobilities …
The agar changed from red to purple, and a noticeable border was present rounding the colonies that exhibited growth on the dish. The ASH agar did not yield a color change. The Imitation agar exhibited a change with S. erasures and the mixed culture, but no change with E. Coli (Table 2). Table 2. Indication …
The table above shows the relationship between the lung capacity average of people who do exercise constantly and the subjects who doses ‘t exercise often. As it can be observed, the blue column (represented by the average of athlete people) shows a clearly advantage above the red column (represented by the average of other subjects), …
Purpose The purpose of this lab was to determine how angle and gravity affects velocity and range. Procedure Materials Projectile launcher Marble Two measuring sticks Tin foil Pencil Set the angle of the projectile launcher to 30 degrees (make sure that the bottom of the launcher is even with the desk). Put the marble inside …
Abstract This experiment focused on extracting and separating pigments of Chloroplast. For the procedure green leaves were grinded in a mortar with some chemicals and the fluid was filtrated to use for further analysis. Stripes of this solution were put on a filter paper and later, after dried placed into a beacon of solvent. After …
Energy (TAP), initially in the form of glucose (macroeconomics) is later formed by condensation reaction into starch (polysaccharide). These alpha-glucose units are attached together by glycoside bonds. Starch is formed after the Calvin Cycle in the Storms. Carbon dioxide is present in the air and the water is gained from precipitation or morning dew. The …
The endocrine system works with the nervous system to regulate and coordinate body functions. While the nervous system works quickly and sends messages directly to specific body parts, the endocrine system takes a longer time to produce a longer- lasting effect. The system operates by releasing chemical messengers called hormones into the bloodstream, which travel …
Also the total amount of energy in a closed system never changes. Along with my wonderful partner Kelvin e thought that energy in a closed system will remain constant throughout unless there is an outside energy such as “work” or friction. We also discussed the differences and similarities between closed and open systems. We wanted …
Observing Various Microinstruction Cases using Population Genetics: Using a Population Gene Pool Simulator, Popsicle Abstract The study of microinstruction was tested in this laboratory experiment through the examination, observation, and analysis of various population conditions, some under the Hardy-Weinberg Theory of Genetic Equilibrium, which would advance the student scientists’ understanding of both microinstruction and the …
There are four parts to the Enzyme Catalyst lab – Activity A, B, C, and D. In activity A, the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catcalled reaction, to study the characteristics of an enzyme mediated reaction, and to observe the effect of …
They belong to the Kingdom Prosiest. 2. What are the three types of multicultural algae? The three types if multicultural algae are chlorophyll which are green algae, Photostat which are brown algae, and roadworthy which are red algae. 3. Are algae author’s or heterozygous? Algae are author’s. 4. What organelle allows plants (and plantlike protests) …

Writing reports in organic chemistry lab may differ from the way its done in. Write your records by hand, either while conducting …
The test tube was haken before the test tubes was placing in the boiling water bath in 3 minutes. 4. After the boiled process, it was continue to whiff the vapor released from the test tube. 5. Record the smell produced. Result: A. Combustion of Alcohols: Types of alcohols I Colour flame I Luminosity I …
The purpose of the Density Lab was to determine the Identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart, taking Into account error analysis and finally classifying the substances. In order to calculate this density, we first found the mass of the container that …
The sample needed to return to the oven for a second heating to insure that all of the water was heated off of the sample. If the mass difference between the first and second heating was greater than 0. 005g, the sample would have been needed to be heated a third time because all of …
There are legion grounds for placing unknown bacteriums. Some of these beings have distinguishable qualities that set them apart from one another. such as the exposure to certain environments. Through out the semester in the research lab. we are able to meet some of the few micro-organisms that we as worlds have come into contact …
