February 25‚ 2013 Lab: Equilibrium of Forces Purpose/Objective: The objective of this lab was to test the first condition of equilibrium for a set of concurrent coplanar forces‚ prove Lami’s Theorem‚ and to determine an unknown mass using rules of equilibrium. Procedure: In the lab‚ we wanted to find at what angles three separate weights would create a net zero force on a force table so that the ring holding the weights was exactly centered in the middle

the rate of peroxidase activity. During the lab‚ the lab group tested 7 test tubes‚ including 1 blank‚ with different amounts of pH 5 buffer‚ H2O2‚ Peroxidase‚ and Guaiacol. After the certain amount of mL per substance was mixed‚ the absorbance readings for the effect of peroxidase concentration were taken from the spectrophotometer. The results for the effect

MATERIAL AND METHODS Stability of cell membrane using pH For the lab experiment for testing the stability of beet cell membranes using pH‚ many materials were used as follows. Obtaining a beet we punch out cores‚ using a cork borer. After washing the cores we put each one inside a separate test tube‚ and added a different pH solution in each one. After 3 minutes in these exposure solutions‚ we took the beet out with a dissecting needle. Then transferred each beet to a separate test tube containing
