I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively

Succession Lab INTRODUCTION: The purpose of our lab was to begin to understand the rates of succession. Succession is a number of persons or things following one another in order or sequence. Considering that all living things follow some sort of order‚ Joey Collins‚ Brian Carman‚ Chris Broadwater‚ Marisa Grondin‚ and I attempted to figure the succession rates of two different forests. In order to do this we used the forest behind the elementary school and the forest behind the track‚ by the

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

Abstract An attitude is a representation of an individual ’s degree of like or dislike for an act‚ object or evaluation. This report aims to conclude whether there is a difference between female and male attitudes towards smoking. It is hypothesised that females will have a more positive attitude towards smoking. Questionnaires using a 5 point likert scale will be utilised to measure each participants’ attitude towards smoking through their responses. Results stated there is no significant difference

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Bioinformatics Lab Report Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create
