Abstract: The reason for performing this experiment was to test the agnostic behavior coming from the male Betta fish. This experiment was conducting by taking a male Siamese fighting fish and placing its fish bowl next to a mirror so it would be able to see his reflection. We also exposed the fish to many others to see if the behavior was the same or different when placed next to: a goldfish‚ a female Betta fish‚ and a zebra fish. My hypothesis was supposed by this experiment and it was observed

The Chromatography of Food Dyes and determination Of the Dyes Present in M&M Candies Procedure To complete this lab‚ I first mixed the solvent solution consisting of the proper ratio of water‚ salt‚ and isopropyl alcohol in a Pyrex measuring cup. I then prepared my chromatography papers for 2 trials by drawing‚ with a pencil‚ the appropriate lines and labels. Using a toothpick‚ I added the color to the paper‚ and then repeated until the color was strong. I repeated this step several more

she recently discovered. As part of her visit she brought several supplies‚ so that my class could watch an experiment of the drug taking action in the stomach. The experiment didn’t go as planned. It exploded and nearly killed Ms.Gura. Now as her Bio-Med class we were subjected to find out whether it was an accident or attempted murder. After the incident we were instructed to remember what we saw during the explosive experiment. Each observation was written into our notebooks for recording purposes

the soil. It consists of ground limestone which is predominantly calcium carbonate. Different soil types behave differently hence there is the need to test for acidity. To raise the pH and lower the acidity or sweeten the soil‚ lime is added. Agricultural lime or garden lime is made from pulverized limestone or chalk. Some types of garden lime are dolomite lime‚ quicklime and slaked lime. Calcium carbonate
