Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain

Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

speeds up reaction without being used up in the experiment) in which it binds on to a specific substrate (reactant) at the active site and lowers the activation energy required to perform that reaction. Enzymes are important biologically because‚ for example‚ the human body performs certain reactions that keep us alive and most of them react at 37 degrees Celsius (body temperature. In each of these reactions‚ there is an enzyme that catalyzes these reactions to lower the amount of energy needed to perform

Grade 11 Physics: Summative Cart Analysis Report 2012 – 2013 Purpose: • To build a gravity cart that moves by using the gravitational potential energy from a falling mass. • To record the motions of the cart by and analyze the motions through d-t‚ v-t‚ and a-t graphs. • To find the efficiency of energy and explain the factors those cause the loss in energy. Procedure Building cart 1. The materials for the cart were gathered. - Shoebox (1) - Pole (2) [0.75cm radius] - Axle (2) [0

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of
