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

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

AndrewGuerrero BIO 125 Lab Due November 14‚ 2012 Practical Exam 1. a. The symbionts (Paramecium) of the termite belong to the kingdom Protista b. Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect

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

causing the body to not have enough acids in the urine. These factors are all very different‚ but are interconnected because an imbalance in any of these factors can lead to imbalances in other areas as well (Wise‚ 2010). The importance of this lab is to analyze factors that may affect urine concentration‚ pH‚ and rate of production (flow rate) though multiple scenarios over a period of 60 minutes. My hypothesis for the urine analysis experiment is that the urine volumes will increase because

Beetroot Practical 2.8 An investigation to find out whether the raise of temperature will increase the permeability of the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim
