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

Title: Homeostasis Date: 19th January 2010 Aim: To observe‚ draw and label the parts of a nephron. Apparatus: Slide of the transverse section of a kidney Pencil Paper Microscope Method: The slide of the transverse section of a kidney was mounted on the microscope and observed under high power. Drawings of the parts of the nephron were made. Calculations of Magnification: Loop of Henle One Ocular Division = 0.22 µm Size of Specimen = 2 ocular divisions Conversion of Ocular

Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

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

Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.

Alvaro Comino LAB REPORT 4 CONNECTIVE TISSUE (SPECIALIZED) I. Abstract In this experiment‚ identification and classification of different types of connective tissue was performed. Also‚ cells and extracellular matrix was to be identified in them. For this‚ different already prepared slides were chosen and observed under the microscope to then identify the different parts. II. Introduction Apart from the bone and cartilage‚ the rest of the specialized connective tissues are divided
