Epidermis Cells Aim: To see if rhubarb changes when it is placed in solutions of different concentrations. Introduction: "Plasmolysis in Rhubarb Epidermis Cells" is an experiment to see whether or not rhubarb changed its cell structure when placed within different types or solutions. "A single layer of plant cell is placed on a micrscope slide and either distilled water or 5% NaCl solution is added to the cells. Osmosis will occur resulting in either turgid cells or plasmolysed cells." (www

Christian Roque and Rogerlio The Mechanisms by which E.Coli Cells Developed Immunities toward Ampicillin due to Plasmid and DNA Consumption U34 Abstract During the ampicillin experiment the ability to transform cells to make them adaptable to their environment was studied. The E.coli bacterial cell was used in order to observe how its DNA was able to change and develop immunity towards ampicillin. In order for this change to occur the use of several plasmids was needed. The plasmids

Introduction: The purpose of this lab was to differentiate chemical changes from physical changes. During the separation lab we were given a test tube with Styrofoam‚ sand‚ salt‚ and Iron fillings in it‚ our goal was to issolate each component from the other. We were given certain tools and materials to help us figure out how to divide the components‚ therefore creating our lab. Doing this lab helped us figure out what component used physical change and which used chemical change‚ it also showed us which

Name: Jayanti Magar Title: Observations of Chemical Changes Date: 02/11/015 Pre Lab Questions: Use what you learned in this lab to answer the following questions. A. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). How would you test this material for the presence of sodium bicarbonate? I would add hydrochloric acid (HCl) with carbon dioxide with NaHCO3‚ and it should bubble and form gas. B. You know what color phenolphthalein and bromothymol

Phase Change Lab Report by Dylan Norford Abstract: The purpose of this experiment is to study the energy changes associated with the phase changes of water. In this experiment we know the water is gaining energy so we know the heat is going to be positive and we can use the equation MCΔT to find the energy change. The specific heat will be 1 and we just have to measure the water to find the mass and take the temperature before and after we start to find the energy change. Background: The science

“Climate Change Over Time” I. Introduction a. In this lab‚ the question being investigated is‚ “Has climate changed over time?” b. The hypothesis is‚ “If CO2 levels affect climate‚ then the climate has changed overtime because of the increased greenhouse effect caused by higher levels of CO2 emissions.” c. Variables: 1. Independent Variable: Amount of CO2 2. Dependent Variable: Climate change II. Background Information Climate is the weather pattern in an area over long period of

The Potential of Pericytes Found in Blood Vessels Do pericytes found in blood vessels create more potential for adult stem cell research? The capability to revert blindness‚ cure diabetes‚ let paralyzed people walk again‚ replace deficient organs with newly grown ones and cure blood diseases are a few of the many potential functions of stem cells. A stem cell is an unspecialized cell that can develop into many different cell types in the body during early life and growth

bottom with the root cap‚ then the zone of cell division next is the zone of cell elongation‚ and at the top of the root is the zone of differentiation. To figure out what section of the root has the highest number of cells in mitosis we did an experiment where we found out cells that are closer to the root tip are more likely to be doing mitosis than the cells that are further away from the root tip. Through the experiment‚ we looked at the zone of cell division‚ which is

As stated previously the purpose of this experiment was primarily based on about chemical changes. Many chemical changes are viewed through a screen‚ or read from a book. In this experiment‚ chemical changes are viewed directly from the eyes of the scientist. The procedure first begins by gathering all needed materials. Next‚ laying the first powder on four wells‚ followed by the next powders‚ each powder was placed on four wells. The liquids were then placed on each powder using the four droppers
