Then after 30 minutes we added a) 3.5 ml buffer b) 0.5 ml ONPG (substrate) c) 0.5 ml of the dilution that was incubated with the buffer (enzyme) Then we allowed the reactions to proceed for the 19 seconds‚ which we used in activity 2 for the pH7. Then we stopped it with 0.5 ml sodium carbonate. Then put it in the sec 20 to determine the absorbance of each solution. The concentration enzyme was obtained by with the standard curve as attached.

a kidney was mounted on the microscope and observed under high power. Drawings of the parts of the nephron were made. Calculations of Magnification: Loop of Henle One Ocular Division = 0.22 µm Size of Specimen = 2 ocular divisions Conversion of Ocular Divisions to ‘µm’ = (2 * 0.22) µm = 0.44 µm Size of Drawing = 14.6 cm Conversion of ‘cm’ to ‘µm’ = (14.6 * 1‚000) = 14‚600 µm Magnification = Size of Drawing / Size of Specimen = 14‚600 / 0.44 = 33‚181.82 X Collecting Duct One Ocular

Lab Exercise 2: Acceleration A. Objective This experiment will provide data to calculate the acceleration of a marble as it rolls down an incline plane over measured periods of time. To do this‚ the marble’s velocity will be determined and then its acceleration. 1. What is the distance between two marks in your inclined plan? -50cm 2. What is the angle of your inclined plan with respect the horizontal? -16degrees 3. Newton’s first law says a body at rest will remain at rest unless

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water

Diffusion and Osmosis Through Dialysis tubing We did this experiment to test the diffusion of different substances through dialysis tubing. We used what we knew about diffusion to make predictions on what we thought the mass of the dialysis tubing to be after submerging them for 30 mins and we knew that diffuse occurs from highest concentration to lowest concentration. Since the dialysis tubings are filled with different substances than what they are being put into then they should all gain
