The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease in weight as the concentration increases. The independent variable in this experiment would

Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules

Concentration Camps in Vienna The Auschwitz concentration camp complex was the largest of its kind established by the Nazi regime. It included three main camps‚ all of which deployed incarcerated prisoners at forced labor. One of them also functioned for an extended period as a killing center. The camps were located approximately 37 miles west of Krakow‚ near the prewar German-Polish border in Upper Silesia‚ an area that Nazi Germany annexed in 1939 after invading and conquering Poland. The SS authorities

Concentration Camps Sydney Quarantillo Grand Island Senior High School “The Holocaust illustrates the consequences of prejudice‚ racism and stereotyping on a society. It forces us to examine the responsibilities of citizenship and confront the powerful Ratification’s of indifference and inaction” said Tim Holden. The holocaust is something worldwide that will never be forgotten and cannot be erased from history. To understand the holocaust learning about Adolf Hitler

Concentration Camps There were many social‚ political‚ and economic causes of WWII. A political cause was the treaty of Versailles. The treaty of Versailles was when we forced Germany to take the blame for WWI. If they didn’t sign the treaty‚ Germany would face invasion. As Germany did not start WWI‚ they felt it was unfair. An economic cause of WWII was the Great Depression. The Great Depression happened world wide. The Great Depression started with the stock market crash. The stock market crash

Osmosis Investigation We are trying to find out what the concentration of the solutions is inside the vacuole of a potato cell. We will investigate how the mass of the potato chips change in different sucrose solution concentrations. We will use osmosis to do this. I will be measuring and controlling many different variables‚ these include; - The dependent Variable Weight of potato chip Independent Variable Concentration of sucrose Control Variables consist of; - 1.

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes
