Lab assignment Purpose The purpose of the experiment was to evaluate diffusion and osmosis process across semipermeablemembranes. The main aim of the experiment was to examine the movement of materials across dialysis tubing. The dialysis tubing was used in this experiment since is a form a semi permeable membrane or tubing that has properties of cellulose and cellophane membranes; thus, the membrane is vital in investigating the properties of real cell membranes. Moreover, it perfectly responds to water as a solvent. Notably, the movement of these materials depended on the concentrated of the solved and the permeable membrane involved in the movement.
The main this experiment was to demonstrate that an active cell allows movement of certain substances across the cell membrane through a different process.
The movement of material across the dialysis membrane was depended on the concentration of the materials across the membrane. Notably, highly concentrated solutions were expected to move from high to low concentrations through diffusion process. Additionally, materials were also expected to move form regions of low concentration to high concentration across the membrane (movement of the experimental material out of the membrane) through osmosis process. Finally, at a certain point or zero concentration gradient no movement of materials across the cell was expected.
Solution in the tube
Concentration of the solution in the tube
Tonicity of the solution (compared to the Cell)
Direction of movement of water
The concentration of any given solution determines the movement of materials across any semi or permeable membrane. The movement of water molecules or materials from regions of high concentration to regions of low concentrated refers to diffusion of materials. The materials are expected move from regions of low concentration to regions of high concentration in a process termed as osmosis. These movements are attempts of creating balance or equilibrium in concentration within the regions around any given cell membrane. Therefore, when the concentrations between the membranes are of equal concentration, there shall be no movement of material across the membrane. Hence, this process well explains different types of movements of materials across cell membranes of living organisms (Beckett 23).

...World Religions World Religions Everything Lives in God From the article, “Everything Lives in God”, everything concerning human being abides in God. God created people in his own image, and his intention was for people to serve him. He gave people brain and understanding to take care of the creation, a duty that we keep by developing the environment. However, we need to show more care by reducing the level of pollution that we cause to the environment especially through the manner in which we handle nature. Personally, I agree with the article, as Christians believe that we do everything in order to appease God. We are aware that during the judgement day, God will judge us in accordance to our actions. Therefore, in my own view... Religions...

... Procedure This experiment requires three cuvettes, a spectrophotometer, a graduated cylinder, dye of three differentcolours. The first step is to fill the three cuvettes with red dye, green dye and blue dye with each holding a dye of different colour. The initial concentrations of these dye is 100% at the beginning of the experiment. The cuvettes are then placed into a spectrophotometer. They are oriented in such a way that their smooth sides lining face the light source to enable easy penetration of light through them. Multiple trials were then performed because the spectrophotometer can only measure one sample at a time. In order to ensure accuracy and precision, it was necessary to re-calibrate the spectrophotometer three... Procedure...

For wireless hotspot we need a wireless connection to be free from use and wired LAN connection to be connected. We will use that wired LAN connection to share the connection wirelessly with others. Keep this noted that some work network do not allow connection sharing because of group policies defined by the network engineers. Step 1: We shall start working by going into the Network and Sharing Center via Control Panel; it can also be quickly accessed by right-clicking on the network icon in the system tray.

My Religion Lab Assignment 4, Thirteen Principles of Faith

...Principles of Jewish Faith Reflect on your reading of the article, “Thirteen Principles of Faith,” and explain at least three (3) principles that pertain to Jewish faith practices. The Thirteen Principles of Faith relate the fundamentals that form the foundation for Jewish faith practices. Among these principles, God’s eternity, the Torah’s unchanging state and the supremacy of Moses as God’s prophet are key principles in the Jewish faith (Maimonides, 1994). The first principle states that God is eternal. The principle labels God as the Creator who is, who was and who always will be. This implies that God is self-existing and was not created. Instead, He existed before creation and will keep existing to the end of times. God’s... of Jewish...

Lab 5 assignment

... This experiment is meant to perform an investigation on the amount of static electri available in various objects. The experiment was done on an inflated balloon, wool sweater, a sheet of tissue paper, an empty 12-oz soda can, a full 12-oz soda can and a hard surface. Hypothesis The woolen sweater will have the highest amount of static electricity. Background static electricity is created when electric charges accumulate on a surface of a body. These charges remain on the surface of the body until they are discharged by being in contact with the surface of another body. All objects have atoms which contain atoms, neutrons and protons. The position of an object on the triboelectric series is used to determine the ability... This experiment is ...

Lab stall while an increase would damage the engine. For energy balance to occur within the internal combustion engine, it is important that the total power generated by the brake power is kept at its peak. Energy performance is an indication of the degree at which the success of the internal combustion polo engine performs its assigned task. The total power is normally developed by the combustion of the fuel in the combustion chamber is greater than the brake power usually referred to as indicated power. This can be calculated as: Relating this value to the values of both the braking power and braking efficiency, we have The balance of the energy in the internal combustion engine will indicate that approximately 1/3 of...

...Lab It is crucial to familiarize with various concepts before conducting lab experiments. One of the importantconcepts for this experiment is solubility, which can be defined as the ability of a substance (solute) to dissolve in another (solvent) (Bauer et al. 216). The estimation maximum quantity of a substance that dissolves in a solvent at equilibrium yields solubility (Brown et al. 120). Qualitative analysis is done to identify elements in the sample used for the experiment. For this experiment, qualitative analysis was employed to establish whether or not a precipitate would form upon adding some acids and bases. A flow chart was used to distinguish between cations in the resultant solution. A flow...

...Should this Ore be mined Introduction Prior to working on the lab experiment, various perceptions should be comprehended such asspectroscopy method utilized in the lab. Calorimeter also known as spectrometer is a tool that is used in figuring out the quantity of light that a given solution absorbs while using various wavelengths (λ).The spectrometer cannot determine the quantity of light absorbed(A) by certain solution unless calibration is done first. The opposite of Transmittance (T %) is Absorbance (A) which can be defined as the quantity of light that is absorbed or transmitted through a sample. Moreover, a highly concentrated solution is, the more it absorbs light, and the less transmitted light...
