follows; 6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂1 There are four variables that affect the rate of photosynthesis; light intensity‚ temperature‚ CO₂ and water.2 However‚ is it possible to count in the colour of light‚ too‚ which I am going to investigate in this lab. Since the photosynthesis takes place in chloroplasts that has chlorophyll‚ the rate of photosynthesis can be affected by different colours of light‚ since the absorption of light changes within different colours. Research Question: What colour of

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Plasmid Grant Zarrinmakan‚ Berkley Kruschke‚ Erika Lawrence. Wed/Fri‚ D-Block‚ 12-January-2015 Introduction Transformation is the genetic alteration of a cell resulting from the direct uptake of exogenous DNA from its surroundings. By doing this lab‚ we will answer the essential question: What influences transformation efficiency? Although there are many possible influences‚ our hypothesis is that plasmid has a positive influence. To test this hypothesis‚ we will set up an experiment in which we
