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

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.

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

Describe two variables that affect the rate of diffusion. Size of material and concentration 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? The molecules were too large to pass through. This is what I predicted

In a flowering plant‚ the water travels from the soil‚ then to the root hairs‚ next to the xylem‚ then into the stomata‚ to the mesophyll cells‚ next to the stoma‚ then finally into the atmosphere. Osmosis is the diffusion of water through semipermeable membranes. Transpiration is the evaporation of water from the leaf. Cohesion is when water molecules stick together. Adhesion is when water molecules stick to‚ not attract. Root pressure is force made by root on water
