“Osteoarthritis” The Musculo-skeletal system FACT SHEET The term "joint" refers to the physical point of connection between two bones. There are numerous joint types throughout the body‚ these being ball and socket joints‚ hinge joints‚ condyloid joints‚ pivot joints‚ gliding joints‚ and saddle joints. A normal joint meets the point of two bones to permit movement. Cartilage is made up of protein that covers the end of bones and aids in protecting the bones and operates as a shock absorber and

Similarly locating yourself in space requires an understanding of the concepts of distance‚ maps‚ and directions. Location in physical space is probably the first step in understanding your physical environment. This unit is going to focus on Map reading and other related concepts that help us to locate ourselves in physical space. A map is a graphic representation of a portion of the earth ’s surface drawn to scale‚ as seen from above

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

Experiment 18 Chemistry 101 Redox Titration: Determination of the Percentage of Iron in a Sample INTRODUCTION The concentrations of redox-active species can be determined by redox titrations. In a redox titration‚ a measured sample of the unknown is titrated against a standard solution of a substance that will oxidize or reduce the unknown. In the present experiment you will take a sample containing iron‚ add acid to dissolve it [thereby converting all the iron to iron(II)]‚ then
