Direction: Read and analyze the following laboratory experiment and answer the following question. PART 2: CARROT POTATO LAB Materials: 6 potato chunks, 6 carrots, 6 sucrose solutions (0m, 0.2m, 0.4m, 0.6m, 0.8m & 1.0 m), plastic cups, and paper towels Methodology: 1. Safety: Wear goggles while completing this lab. 2. Slice a carrot and potato into discs that are approximately 5 cm thick. 3. Use a cork borer to cut the carrots and potatoes. Do not include any skin on the cylinders. You need four apple and potato cylinders for each solution. 4. Keep a carrot and potato cylinders in a covered container until it is your turn to use the balance. 5. Determine the mass of the four cylinders together and record the mass. Put the four cylinders into the plastic cup container. 6. Label the containers with the color of the solution and your initials. 7. Pour the colored solution into the containers and cover with plastic lid. 8. Let stand overnight. 9. Remove the cores from the beakers, blot them gently on a paper towel, and determine their total mass. 10. Record these final masses. 11. Discard solution in the sink and used carrot and potato /cups in the trash. Questions: 1. What is the independent variable in the experiment? Why? 2. What is the dependent variable in the experiment? Why? 3. What possible variables should you be sure to hold Constant? Give three and explain why. 4. What is your control variable? Why is this a valid control?

MATERIAL METHOD RESULT SUMMARY     Lecia DCM3D confocal Microscope 1) Straumann (Straumann AG, Waldenburg, Switzer- land) 2.2mm in diameter (for short, A) (2) Nobel Biocare (Nobel Biocare AB, Goteborg, Sweden) 2.0mm in diameter (for short, B) Xive Implant System (Friadent GmbH, Mannheim, Germany) 2.0mm in diameter (for short, C) (4) Global D (French) 2.5mm in diameter (for short, D) (5) Sweden & Martina (Padova, Italy) 2.5mm in diameter (for short, E)   The microstructural parameters used by the discriminatory analysis revealed many differences between the five manufactures in terms of roughness of the drilling surface. Marenzi et al (2018) have considered that Surface micromorphology, which affects the contact between the drill and bone, has been shown to contribute to heat, wear, and corrosion phenomena due to material abrasion and corrosion resistance through several surface texture indicators Can be seen as a factor. Not only the design, but also the…

Direction: Read and analyze the following laboratory experiment and answer the following question. PART 3: PLASMOLYSIS Materials: safety goggles, red onion, dropper, slides & cover slips, tweezers/ forceps, compound microscope, iodine, small knife, water, salt (5% and 10% solution) Methodology: 1. With goggles on, carefully cut the onion into wedge shaped pieces using a knife. 2. Use an eye dropper to place a drop of water in the center of a microscope slide. Use the tweezers to peel a thin layer of skin tissue from the thick part of the onion wedge and place it in the center of the microscope slide. 3. 4. 5. Add a drop of water and a drop of iodine over the onion tissue on the slide. Carefully lower a cover glass slip at an angle on the stained tissue to allow air bubbles to escape. 6. Examine the prepared slide under the compound microscope at 100X magnification. 7. Record what the cells look like. 8. Prepare a 5% salt solution by adding 5 grams of salt (measure with balance) per 100…
