FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

Unit 1. Lab 1. Fixed Line vs. Cellular Debate A cellular network or mobile network is a wireless network distributed over land areas called cells‚ each served by at least one fixed-location transceivers known as a cell site or base station. In a cellular network‚ each cell uses a different set of frequencies from neighboring cells‚ to avoid interference and provide guaranteed bandwidth with each cell. When joined together these cells provide radio coverage over a wide geographic area. This enables

OF INVERTASE FROM YEAST AND EFFECT OF pH ON ENZYMATIC ACTIVITY Jenelle C. Faustino‚ John Gambit B. Garcia‚ Fatima S. Jusay‚ Oliver Alexander B. Lao and Eunice L. Licudine Group 4 2 E Medical Technology Biochemistry Laboratory ABSTRACT Enzymes are substances that are produced by living organisms and act as catalysts in order to speed up or chance a chemical reaction without changing itself at the end of the reaction. Invertase was extracted first from baker’s yeast. Determination of

Answer to Questions 1. Describe the type of meter movement used in the analog meters. The two analog meters—namely‚ the voltmeter and the ammeter—employ the d’ Arsonval meter movement. The movement consists essentially of a movable iron-core coil mounted on a pivot between the poles of a permanent magnet. When current flows through the coil‚ it creates a torque which causes the pointer to deflect. The amount of current through the coil determines the deflection of the pointer‚ which is registered
