Stress and Cellular Membranes Bio Lab SBI 4U1 Due: Sept 24th‚ 2010 For: Ms. Barton By: Ameema Saeed Introduction: (See attached lab) Purpose: (See attached lab) Hypotheses: Tap water will cause no damage to the membranes. The extreme temperatures of the water cooled to 0°C‚ and heated to 94-100°C will greatly damage the membranes. Extreme heat will be more damaging than extreme cold. The more concentrated the solvent‚ the more damage it will cause to the membranes‚ therefore the solvent

The plasma membrane surrounds the cytoplasm of living cells‚ physically separating the intracellular components from the extracellular environment. It also plays a role in anchoring the cytoskeleton provide shape to the cell‚ and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The plasma membrane helps maintain homeostasis by diffusion and osmosis. Osmosis is the diffusion of water across a membrane. Diffusion is the process by which molecules

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

of the Cell Overview: The Importance of Cells • All organisms are made of cells. o Many organisms are single-celled. o Even in multicellular organisms‚ the cell is the basic unit of structure and function. • The cell is the simplest collection of matter that can live. • All cells are related by their descent from earlier cells. Concept 2 Eukaryotic cells have internal membranes that compartmentalize their functions Prokaryotic and eukaryotic cells differ

Parts of the digestive system The digestive system consists primarily of the alimentary canal‚ a tube that extends from the mouth to the rectum. As food moves through this canal‚ it is ground and mixed with various digestive juices. Most of these juices contain digestive enzymes‚ chemicals that speed up reactions involved in the breakdown of food. The stomach and the small intestines‚ which are parts of the alimentary canal‚ each produce a digestive juice. Other digestive juices empty into the alimentary
