flask using a volumetric pipette. The volumetric flask was then filled to the mark with distilled water. The flask was covered with Parafilm and inverted to mix. The next part of the experiment was to determine the Vitamin C in a solution of known concentration. Observations of the Vitamin C sample and the amount found on the label was recorded. A tared piece of weighing paper was used to weigh 0.27 g of Vitamin C. The Vitamin C was then transferred to a clean 50 mL volumetric flask. The flask was filled

Concentration Camps Can you imagine being a Jew and living during the Holocaust? One day you are at your house doing your normal routine‚ and the next minute you are being loaded onto a cattle truck. You would be taken to the most horrible place imaginable. A concentration camp. A concentration camp was where people were kept without trial. They were kept in terrible conditions and had no rights. Concentration camps had forced labor‚ mistreatment‚ starvation‚ disease‚ and random executions. Concentration

membranes with little difficulty. This process is known as osmosis. The direction of motion is regulated by the relative concentrations of water and dissolved substances inside and outside the cell. Water will move from an area of high concentration of water molecules (low concentration of dissolved particles) to an area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only

I. Research Question What are the effects of different sucrose concentrations on potato stripes which have been submerged in a range of solute sucrose concentrations. II. Background Information Osmosis is one of the four methods of moving particles across membranes along with simple diffusion‚ facilitated diffusion‚ and active transport. Water is able to move in and out of most cells freely. Sometimes the number of water molecules moving in and out is the same and there is no net movement‚ but at

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that

The history behind Auschwitz Concentration Camp Did you know that Auschwitz Concentration Camp was the largest camp to be set up by Nazi Germany? Auschwitz was the most notorious camp in Poland. “ As Nobel laureate Elie Wiesel warned years ago‚ to forget a holocaust is to kill twice.” What kind of treatment was used in the camp? Who were the leaders of this camp? Where did the people in this camp come from? Many people lost their lives to this labor camp. Auschwitz was a very brutal and harsh place

Effect of Solute Concentration on the Mass of Apples Introduction Background: This lab involves the testing and measuring of water potential. Water potential (ψ) is the tendency of water to diffuse from one region to another. It measures the free energy available in water to do work. Pure water has a water potential of 0 (kpa--unit?). Water will move from an area of higher water potential to an area of lower water potential. Several factors‚ including temperature‚ pressure (ψp) and solute concentration
