Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5

Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

It prevents contamination from unknown cultures. 3. Does your lab report contain any messages when your inoculation was not complete? What change in the traffic signals indicates an unsuccessful inoculation? Answer: The lab report does not contain any messages about inoculation. There’s only a reference if auto-inoculation was used. The traffic signal light will turn red if the inoculation was unsuccessful. 4. Does you lab report contain any messages when you don’t follow aseptic procedures

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye
