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

Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

Environment Can Effect Enzymes Introduction: In a chemical reaction there sometimes can be a catalyst present known as an enzyme. An enzyme is a protein that speeds up a chemical reaction by lowering the amount of activation energy required to start the reaction. By lowering the activation energy‚ more of the substrate is able to participate in the reaction‚ speeding it up. Enzymes are substrate specific. The substrate is what the enzyme bonds to. That is to say that enzyme A will only react with

molecules‚ such as RNA molecules in the “RNA World” hypothesis‚ essential to the most popular hypotheses about the origin of life on Earth? Becuase‚ RNA is able to store genetic info just like DNA‚ and is also able to catalyze chemical reactions like an enzyme‚ so RNA could have played a big role in the evolution of cellular life. 4) How might similarities and differences in genetic codes‚ or the proteins built as a result of these codes‚ be used to determine how closely related different species are

Title: “The Effect of Substrate Concentration‚ Enzyme Concentration‚ pH and Temperature on Enzyme Activity” Abstract: In the following experiments we will measure precise amounts of potato extract as well as Phenylthiourea‚ combined with or without deionized water and in some instances change the temperature and observe and record the reaction. We will also investigate the different levels of prepared pH on varying samples of the potato extract and the Phenylthiourea and record the results.

Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

Ayaan Nadeem SBI 4UO-A Tuesday‚ February 27‚ 2013 Ms. Balmer Pineapple Jelly Enzyme Lab Discussion After completing the Pineapple Jell-O Enzyme lab‚ the final results were that the canned pineapple formed the jelly while the fresh pineapple did not. Pineapple In order for this to have occurred‚ there has to be a comparison between fresh and canned pineapple in terms of their physical and chemical properties. The physical properties of fresh pineapple are that it is sweet‚ ripe and raw.
