Version 2: Identifying Dominant Plant Species 1- Hypothesis Based on the results‚ the bunchberry plant‚ with a scientific name of Cornus canadensis‚ was most frequently seen in station four‚ the ecotone‚ and second most in station five‚ the forest which is most likely in the lower forest since it has a similar environment to that of station four‚ and third most in station three‚ the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

Introduction In this experiment‚ to measure residency effect in crickets‚ the experimental organism is the house cricket‚ Acheta domesticus which is native to southwestern Asia but lives commonly in the eastern side of the United States (Ghouri 1961). I hypothesize that a residency effect will take place when a “intruder” male is placed in the container of a resident male‚ causing the cricket who owns the territory to fight more aggressively and remain dominant over that area. The independent variable

the stroop effect. It was this type of research that inspired others and prompted them to conduct research of their own in this area of study‚ and that is exactly what was done for this laboratory experiment as well. The overall hypotheses for this experiment were‚ as expected‚ conclusive with the results‚ however‚ there was a discrepancy in the hypothesis of experiment two. The comprehensive hypotheses for this experiment were that in each experiment‚ there would be a significant effect in reaction

The effect is named after John Ridley Stroop‚ who published the effect in English in 1935 in an article entitled Studies of interference in serial verbal reactions that includes three different experiments.[1] However‚ the effect was first published in 1929 in German‚ and its roots can be followed back to works of James McKeen Cattell and Wilhelm Wundt in the nineteenth century.[2][3][4] In his experiments‚ J. R. Stroop administered several variations of the same test for which three different

Lab Report 3: Combustion of Magnesium and Specific Heat of a Metal C4C Jeffrey Silvin Fall 2017 Major Kittle Chem 100 T1 Introduction The purpose of this lab was to determine an experimental value for the heat of formation of MgO with Hess’s Law and then use the result to find percent error. To do so‚ approximately 50 mL of 1.0 M HCl was added to a calorimeter. Initial temperature was measured and then 0.25 g of Mg was added. After the reaction is completed the maximum temperature was recorded.
