In our hypothesis we predicted that the enzymes in the pineapple will denature when the temperature is changed. The prediction was partly correct. Pineapples have special enzymes that denature gelatin molecules. Which is the reason why the pineapple and gelatin test tube remained filled with liquid‚ instead of turning into jelly which gelatin does when it’s molecules are not disturbed. Why our hypothesis was partly incorrect was lacked depth in that when changing the temperature by heating the pineapple

Medicine Analysis – Synthesising Aspirin results After recrystallisation differences between the crude and purified aspirin were noted. The impure (crude) aspirin was powered and fluffy with small clumps and was slightly yellow in colour whereas the pure aspirin has a less fluffy crystalline powder and was whiter. This showed distinct differences in the two substances but similarities were also apparent showing aspirin‚ in some level‚ was created. Before recrystallisation the crude aspirin could

10. Errors and Redesign. Throughout this experiment a number of random and procedural errors were apparent; these errors could have affected the results of the experiment in a number of ways. One experimental error that occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by

Prior to starting the Trinity TEFL course‚ I had little teaching experience in a classroom environment and only in my own language. I had little knowledge of the teaching techniques and methodology used to teach a foreign language and having to put theory into practice almost from day one seemed quite daunting. From one lesson to another I learnt different type of technique used in the classroom: using flashcards‚ elicit vocabulary‚ concept checking throughout‚ encouraging pair work and group

This post is the thoughts and points. after today’s lecture (8/31). In the novel‚ Like Water for Chocolate‚ by Laura Esquivel‚ love tensions and rebellion play a role into both the theme and the plot. The popular TV reality show and “soap opera” like content‚ The Bachelorette follows one lady looking for love in the mist of many male suitors. In this instance‚ Tita‚ is the contestant. She narrowed it down to her final two‚ John Brown and Pedro. Let’s get to know our contestants background. John Brown

Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

Fan Cart Lab We did a fan cart for our physics class the other day. To set up the lab first‚ we measured the effect of the mass of the fan cart on the acceleration of the cart. The mass of the fan cart was the independent variable and acceleration was the dependent variable. We kept the speed of the cart on medium‚ and calculated the acceleration and motion. As a result‚ we had figured out that the bigger the mass the slower the acceleration‚ as we all should have known. To calculate this we used

One size doesn’t fit all. Many companies find that the best way to get ahead is to expand ownership boundaries through mergers and acquisitions. For others‚ separating the public ownership of a subsidiary or business segment offers more advantages. At least in theory‚ mergers create synergies and economies of scale‚ expanding operations and cutting costs. Investors can take comfort in the idea that a merger will deliver enhanced market power. By contrast‚ de-merged companies often
