The respiratory system is a vital factor of gas exchange due to its structures. The structure provides an efficiency to the process. Gas exchange requires an efficient system because it is a process through which blood circulates around the body‚ collects oxygen‚ delivers the oxygen to the organs that require it and releases carbon dioxide. oxygen and carbon dioxide enter and exit the body in opposite directions across a respiratory surface area that supplies enough oxygen to allow the process to

Table Tennis Table tennis‚ also known as ping-pong‚ is a sport in which two or four players hit a lightweight‚ hollow ball back and forth using table tennis rackets. The game takes place on a hard table divided by a net. Except for the initial serve‚ players must allow a ball played toward them only one bounce on their side of the table and must return it so that it bounces on the opposite side. Points are scored when a player fails to return the ball within the rules. Play is fast and demands quick

Effects of pH on the Function of Enzymes Rena Mototani Glen Rock High School Advanced Biology 2014-2015 Effects of pH on the Function of Catalase Rena Mototani Problem: How does the pH of a cell affect the function of the enzyme catalase? Introduction In this lab‚ we experimented the effects of pH on the function of the enzyme catalase. Catalase is an enzyme that brings about the reaction by which hydrogen peroxide is decomposed to water and oxygen (Encyclopedia Britannica). The

"Do different concentrations of solutions determine the mass of a potato?" Introduction: The way to get the full results of this lab was through the process of osmosis. Osmosis is the movement of water across a membrane into a more concentrated solution to reach an equilibrium. When regarding cells osmosis has three different terms that are used to describe their concentration. The first of these words is isotonic. Cells in an isotonic solution show that the water has no net movement and the amount

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

uses for fuel include everyday uses in our homes‚ running vehicles‚ and the use in manufacturing plants and other businesses that run on fuel. BMI oil and gas forecasts have been extended to cover a 10-year period‚ providing a guide to likely supply and demand trends from 2008 to 2018 (Oil & Gas Outlook: Long-Term Forcasts‚ 2009). Gas demands have been rising because environmental concerns have caused fuel to be the choice for power in many parts of the world. It is suggested that the fuel

Energy Balances‚ Numerical Methods Design Project Production of Acetone Process Description Figure I is a preliminary process flow diagram (PFD) for the acetone production process. The raw material is isopropanol. The isopropanol (lPA) feed is a near azeotropic mixture with water at BB wt yo IPA at 25"C and I atm. The feed is heated‚ vaporized‚ and superheated in a heat exchanger (E-401)‚ and it is then sent to the reactor (R-401) in which acetone is formed. The reaction that occlrrs is shown

By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II.
