Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate

Transformation Of Escherichia Coli With pGLO Plasmid April 24‚ 2013 ABSTRACT: This experiment focuses on genetic engineering and transformation of bacteria. The characteristics of bacteria are altered from an external source to allow them to express a new trait‚ in this case antibiotic resistance. In is experiment foreign DNA is inserted into Escherichia coli in order to alter its phenotype. The goal of the experiment is to transform E. coli with pGLO plasmid‚ which carries a gene for ampicillin

Questions: 1. Why is a conical flask‚ rather than a beaker‚ used in the experiment? – To allow easy mixing of solutions by swirling. 2. Why is the funnel removed from the burette after adding the acid solution? – so that the drops from the funnel will not fall into the burette. 3. In using a burette‚ why is it important to (a) rinse it with a little of the solution it is going to contain? – to remove any residual water and so avoid dilution of the acid solution when it is poured into the burette
