Canker sores are painful‚ open sores on the inside of the mouth and cheek. They may be white or yellow. The sores usually heal in 1 to 2 weeks. Women are more likely than men to have recurrent canker sores. CAUSES The cause of canker sores is not well understood. More than one cause is likely. Canker sores do not appear to be caused by certain types of germs (viruses or bacteria). Canker sores may be caused by: • An allergic reaction to certain foods. • Digestive problems. • Not having enough

Investigating the effect of salt concentration in beetroot at different temperature Abstract The aim of the experiment is to find out the effect of salt concentration in a beetroot at a different temperature. The experiment will help to identify the effect of salt concentration in beetroot at different temperatures. After this‚ equipment called colorimeter will be used to take a reading for absorbency. The readings for the absorbency will be repeated three times in order to find the mean of

Independent variable: Temperature of beetroot Dependent variable: Absorbency of light Hypothesis: As temperature rises to its optimum temperature‚ the absorbency of light will increase because protein is an enzyme and will therefore be affected by temperature. This is because more beetroot dye will pass through the cell membrane and then into the distilled water. The deeper the colour of the beetroot dye‚ the higher the absorbency of light. Beetroot vacuoles have red pigments which can’t

molecules) demonstrate that there is an unbroken link between modern cells and the first primitive cells that appeared on earth. In the cells of a beetroot plant‚ a substance called anthocyanin is contained within the plasma membrane. It is anthocyanin‚ which gives the beetroot its characteristic blue/purple colour. If a cell is damaged in a beetroot plant and the membrane is broken‚ the anthocyanin ’bleeds’ from the cells like a dye. It is this characteristic that

EXPERIMENT ONE- BIOLOGY MODEL Answers TO DETERMINE THE EFFECT OF CHEMICALS AND TEMPERATURE ON MEMBRANE DESTRUCTION AND PERMEABILITY IN BEETROOT (Beta vulgaris) Introduction The cell membrane is made up primarily of phospholipids and proteins which contribute to its selectively permeable nature. The function and permeability of the cell membrane depends on its intact structure. When destroyed‚ the permeability of the cell membrane is disrupted causing cellular contents to leak out. The cell

Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

Beetroot Cells with High temperatures and low pH solutions Friday 15th March 2013 Abstract (50) The aim of this investigation was to study the effects of temperature and a low pH solution on beetroot cells. Introduction (200) The general belief amongst our group members was: an increase in temperature will damage the permeability of the plasma membrane. Also‚ the heat will break away the permeability. If the pH solution is 7 or greater there will be no change but the lower the pH the more proteins

BRIEF INTRODUCTION: Beetroot cells contain a red pigment stored in the cell vacuole in the membrane to prevent leaking out from the cell. In this experiment we used several solvents to calculate which one made the cell release more pigment. RESULTS: A table showing the results of the intensity of the color and the absorbance of the liquids with the different solvents.
