Lab 1 Diffusion‚ Osmosis‚ and Water Potential of Glucose Problem: What effects will glucose have on diffusion‚ osmosis‚ and water potential? Background: All living things have certain requirements they must satisfy in order to remain alive. These include exchanging gases (usually CO2 and O2)‚ taking in water‚ minerals‚ and food‚ and eliminating wastes. These tasks ultimately occur at the cellular level‚ and require that molecules move through the membrane that surrounds the cell. There

Biology 101 : A Crash Course The school bell rings on the first day of school. Your students start to trickle into the class little by little. They see the various microscopes and dissecting equipment‚ and their eyes go wide. Biology is a very fun and interactive subject for students‚ which makes it all the more exciting to be able to teach it. Ever since I took sophomore biology in high school I haven’t been able to stop thinking about it. My teacher just always seemed like he was having as much

IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

such as the red maple were located in stations four and five. It was noticed that the area in which bunchberry plants grew were shady areas because the large trees were blocking the sun light from reaching them. Plants need sunlight to conduct photosynthesis in order for growth to take place; however‚ too much exposure to the heat the sun brings may cause a plant to become too dry through the process of evaporation which supports the earlier prediction that a bunchberry requires a moist‚ cool environment

Conclusion I predicted that if the decolorization of DPIP is caused by photosynthesis and not cell respiration and spinach extract containing chloroplasts and mitochondria is incubated with DPIP‚ then the rate of DPIP decolorization should be higher if in bright light verses dark light because DPIP is reduced by photosynthesis and not by the mitochondria or any other cellular function. If DPIP was only decolorized by chloroplasts‚ then the percent transmittance of chloroplast suspensions would be

hold another paperclip at the appropriate distance: six cm‚ seven‚ eight‚ nine‚ ten‚ twelve‚ fourteen‚ sixteen‚ eighteen‚ and twenty centimeters. 5. Lab partner must close eyes tightly. 6. Starting with the largest distance‚ place either one or two ends onto your partners skin (ALTERNATE RANDOMLY so the partner can’t guess!!!) 7. Have lab partner tell you how many ends they can feel. Do this 5 or 6 times. 8. Then try the next smaller distance and repeat steps 6 and 7. 9. Record
