Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

the new Communist Party of the Philippines (CPP)‚ and the Muslim separatist movement of the Moro National Liberation Front (MNLF). One of his first actions was to arrest opposition politicians in Congress and the Constitutional Convention. Initial public reaction to martial law was mostly favourable except in Muslim areas of the south‚ where a separatist rebellion‚ led by the MNLF‚ broke out in 1973. Despite half-hearted attempts to negotiate a cease-fire‚ the rebellion continued to claim thousands

Solutions and Their Concentrations 1. Molar Concentration or Molarity – Number of moles of solute in one Liter of solution or millimoles solute per milliliter of solution. 2. Analytical Molarity – Total number of moles of a solute‚ regardless of chemical state‚ in one liter of solution. It specifies a recipe for solution preparation. 3. Equilibrium Molarity – (Species Molarity) – The molar concentration of a particular species in a solution at equilibrium. 4. Percent Concentration a. weight

Everything Happens For a Reason Both The Odyssey by Homer and Oedipus Rex by Sophocles‚ were based in the context of ancient Greek culture but each was written during different time periods. The Gods played an enormously influential role in the lives of the Ancient Greeks. The Odyssey was written during the Greek Heroic Age (1500-1100 B.C.E.) and Oedipus Rex was estimated to be written around the 430s B.C.E. during the Age of Pericles when Athens was at its height of political and cultural power

During the World War II‚ Jews were separated into two groups the healthy and the unhealthy. The unhealthy
