My First Lab Report: Diffusion and Osmosis To begin‚ this is my first time doing an experiment and a lab report for biology’s class. Although‚ it was a little hard at the beginning‚ my team and I got the hang of it and we finished it on time. It was actually kind of fun. There were three steps in the experiment: 3.1 A – Molecular Movement: In this session‚ I was observing a sample and determining if there was a movement or not. 3.1B –Diffusion through semi-permeable membrane dialysis tube: In this

Aim: The aim of this experiment is to investigate the movement of water into and out of plant cells by osmosis. The cells chosen for study will be taken from potato tubes as they provide a ready supply of homogeneous material. I did the investigation in two parts‚ the first part of my investigation was my preliminary investigation and then I did my official investigation. In both of my investigations there are several similarities‚ such as fair testing‚ variables‚ key variables‚ reliability

THE ANALYSIS OF INTRODUCTION AND CONCLUSION STRATEGIES USED IN OBAMA’S SPEECHES A. Introduction 1. Background According to Slagell (2009)‚ in everyday language‚ public speaking refers to the communication practice of a speaker sharing ideas with an audience primarily through speech. The process of sharing ideas for the audience can be done in many ways such as speech or also called as oratory. Following Astuti (2011‚ p.23-26) stated that public speaking including speech has many important

Reverse Osmosis Application Assignment Osmosis is the dissemination of water atoms through a semi-permeable layer from areas of high to low concentration in the direction that tends to equalize the solute concentration on both sides. In real life osmosis is found in roots of plants retain water from the dirt‚ and kidneys taking water from blood [5]. Reverse osmosis is the removal of solute from water by applying pressure to the water and moving the solution through a semi-permeable membrane. It is

that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to enter the inside of the cell. Osmosis is the process of water movement across the membranes from an area of high water concentration to an area of low water concentration to reach a sense of equilibrium. Diffusion is what enables osmosis to occur.

1.What Is Cancer? CANCER‚ a 6 letter word that makes our world upside down. Cancer is not just one disease‚ but a large group of almost 100 diseases. Its two main characteristics are uncontrolled growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled‚ cancer can result in death. 2.How does cancer occur? The body is made up of trillions of living cells. These cells grow‚ divide‚ and die in

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no
