Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

Conclusion Questions: Use complete sentences. 1. What does the iodine used in the lab represent in the cell? 2. As the size of the cell increases‚ which increases faster: cell surface area or cell volume? 3. As cell size increases‚ what happens to the surface area to volume ratio? Give examples from the lab. 4. According to your drawings

Guide Questions What effect does increasing the tension have on the number of segment formation? Explain your answer. According to a theory‚ changing the tension will definitely change the number of segments. From equation three‚ the frequency is directly proportional to the number of segments and the tension and inversely proportional to the mass density and the length of the wire. Manipulating the formula to solve for the number of segments‚ n‚ is inversely proportional to the tension‚ thus

Lab Report DIFFUSION AND THE EFFECT OF AMYLASE. Aim: We will interpret and explain the activity of an enzyme added to a solution. We will analyze reactions in different pH ranges. The starch solution will appear blue when mixed with iodine. But after mixing the enzyme amylase to the starch‚ the starches are broken down into simple sugars. Now‚ when the iodine is added‚ no color change exist. Instruments and materials used: 1.) Dialysis bags x2 2.)

Kiphart AP Biology Lab Report Number One Mrs. Irvine Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of water through

Week 1 Lab Name_________ Part I - Directions: For the function we are going to estimate the area under the curve using the trapezoidal rule where n = 5 by doing the following: 1. Divide the interval into 5 equal pieces. How long is each piece? This will represent the width of the rectangles we will use to estimate the area in gray above. What will the x-values be for the endpoint of each piece? Width of rectangle = 0.4 .2 .8 1.6 2.4 3.2 2 2. Evaluate f(x) for x1 to x6
