...?The Effect of Lysozyme Solution on Micrococcus lysodeikticus Cell Counts Introduction Bacterial cell quantification is useful in many areas of biology, in that it allows us to know the number of cells, or the viable cell count. This information can be used in antibiotic sensitivity testing, or infection severity, for example. Bacterial cell quantification can be done in several ways, but this experiment will be using a spectrophotometer to measure the relationship between the bacterial cell concentration and the absorbance of light. Results using known concentrations are often used to...

...to inadequate wiping of pipette, improper mixing or uneven distribution in counting chamber. The low value can be due to dilution of contents in pipette by saliva and use of non standard counting chamber and improper cover slip adjustment. Error calculation can result in both high and low values. Even if the second value is correct the women is still anemic. To confirm the findings of both tests a packed cell volume (PCV) or hematocrit test may be done which will give the correct percentage of erythrocyte volume in the blood. Section B B1 i) According to the JNC 7 Report the BP reading of subject N which is reported to be 125/78 is classified as prehypertension stage since it is greater than the...

...in a row. It is a common component of fresh water plankton, which is most commonly used in the experimental purposes of water pollution and photosynthesis. It is also crucial in the process of sewage purification because it releases oxygen, which is necessary for the breakdown of organic matter, hence terminates the functions of harmful substances. In this project, we get to experiment on the growth conditions and developments. The main elements in test here will be light and pH since we discovered that the plant grows well under neutral pH. The main methodology in this project is to grow one experimental set in direct sunlight while the other will be places under no sunlight. The main conclusion will be...

...? Working Memory Experiment: Assessing the Relationships Shared by Different Tasks Measuring Working Memory Capa This experiment was carried out to test the relationships between different tasks that measure Working Memory capacity. It was proposed that all four tasks – MU, OS, SS and SSTM – would be significantly correlated and that MU, OS and SS would share stronger relationships among themselves than with SSTM. Data was collected from 444 students, of which data on 406 was deemed acceptable for analysis. The correlations computed suggested that both the hypotheses could be accepted, and that although all WM capacity tasks did share similarities, they did also indicate the existence of...

...Density Lab Report Charnelle Palama and Tanya Ono (Group H) Chaminade This experiment aims at using the Archimedes principle to determine the density of post-1985 pennies. The experiment used water determined corresponding masses and volumes of pieces of pennies. This was then used to determine the pennies’ average density. The results yielded a significant relationship between mass and volume at ‘0.05 level of significance’ and a corresponding p value of 0.0009. The results also identified an experimental density of 7.54 g/mL for the pennies. This was different from a theoretical density of the pennies that is 7.18 g/mL. The experiment therefore yielded a percentage error of 5 percent...

Reflection
In conclusion, it is acknowledgeable that determination of a gas’ molar mass is a complex process that entails application of key chemistry concepts, specifically buoyancy, Avogadro’s principles, and ideal gas laws. Personally, I was impressed by all procedural steps of the experiment. Actually, I would be more than willing to reproduce any part of this experiment at any time. However, I would be pleased with the experiment if any suitable gas other than hydrogen is used in the procedures. Use of hydrogen involved substantial risks of accidental ignition and...

...Construction of a Solar Cell for Electrolyzing Water Introduction The significant role that energy plays in human life is undisputable. Despite the numerous uses of energy in industries, homes, and transportation for various purposes such as heating and lighting, most of the energy sources are non-renewable, and they are under threat due to over-exploitation (Bube 1). Thus, there is a need to develop alternative renewable sources of energy such as the solar. In this experiment, a solar cell would be constructed for conversion of sunlight energy into electrical power for use in electrolysis of water. Even though silicon cells are more efficient than solar...
