OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

The Effect of Osmosis on Differences of Amount of Sucrose Osmotic Pressure and its Influence on the Concentration of Sucrose in Solution Brennan Montoni Movement of molecules and Ions Names of Lab Partners Biology 110 March 23‚ 2011 Code of Academic Integrity INTRODUCTION: During the process of osmosis‚ water will move across a differentially permeable membrane. The water will transfer from a region of lesser solute concentration to a region of greater solute concentration

There are many kind of cell membrane disease‚ There are : Cystic Fibrosis Cystic Fibrosis is a disease that cause by gene mutation of CFTR Protein. CFTR it’s stand for Cystic fibrosis transmembrane conductance regulator. This disease causes too much production of thick mucus‚ then the mucus will blocked the ion transport in epithelial cells that line the passageways of the lungs‚ pancreas‚ and other organs. If the passageways of the lungs is blocked by the thick mucus‚ it will make the sufferer

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:

Dissolution Rates of Paracetamol in Different Temperatures Rowan Boreham and Cameron Matheson Introduction Panadol Rapid Soluble‚ is paracetamol based a medical drug that treats pain and discomfort associated with headache/tension headache‚ migraine‚ toothache‚ muscular aches‚ cold and flu symptoms‚ sore throat and menstrual pain (Medsafe‚ 2012). While there are other recognised sources of pain relief‚ Panadol has been widely recognized as a being of a high standard treatment for pain. There for

Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane‚ while osmosis is the process in which water molecules move passively from a region of higher water potential to a region of lower water potential through a differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium

Usman Omid Biology IB 1A The Effect of Temperature on Beetroot Membranes _Aim_ This practical will test the effect of temperature on the integrity of the membranes‚ _Introduction_ The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged‚ then the betalain leaks out. The amount that leaks out can be assessed‚ as the leaked out pigment will color the water surrounding the cells. This information can

Truity Results In this analysis‚ I will discuss my Truity personality assessment‚ how I agree with the results and a few milestones that have brought me to my trait perspectives. In conclusion‚ I will apply the concepts of Freud‚ Erikson‚ Kohlberg and Piaget. Based on my personality assessment test results from Truity.com I could be an extrovert or an introvert. The website said that my score was right on the borderline for the Extraversion VS. Introversion dimensions. My results stated that this

Joanna Packham ENG 111 Reverse Osmosis in Our Life My husband and I installed a reverse osmosis drinking water system in our home. I have traveled a lot recently and met lots of people including engineers on the yachts that thought me a lot abut reverse osmosis systems. They explained to me that RO are declining in popularity because they remove the minerals as well the impurities from the water. Long-term consumption of filtered water had negative health effects. I was asking myself is RO water
