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

Name: Mugabe Rodrigue Class: Grade 11B Subject: Biology Topic: DNA Extraction From Onion Date: 20/1/2014 Introduction: DNA‚ or deoxyribonucleic acid‚ is the hereditary material in organisms. Nearly every cell in an organism has the same DNA. Most DNA is located in the cell nucleus.The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of these bases determines the information available for

water with no chlorine. Clean an area of space you think is suitable‚ preferably lab tables. Take out 5 beakers. Take out an electric mass scale. Turn on electric mass scale (power button) and place a beaker on top of the scale. Make sure to only measure one beaker at a time. Wait till the digits on the screen slow down and stop at a number. The number it stopped at‚ that is the number you will right down in your lab book (that you will get out) as scrap notes. After you have measured each beaker

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

too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute‚ the higher the mass of the solution. Methods and Materials: For part A of the experiment‚ the following items are needed: Dialysis tubing‚ IKI solution

Enzymes Introduction This study allows the investigation of enzymatic reactions behavior. An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction. In this stimulation the amount of product produced during the course of an enzymatic product produced during the course of an enzymatic reaction will be measured. Hypothesis 1: What is the estimate optimal of ph? Hypothesis 2: What is the estimate optimal of temperature
