similar characteristics to one of a shrimp. Another name for it would be the fairy shrimp. During this observation‚ only two eubranchipus were identified. We did not have as many eubranchipus as the other groups but we were able to put one under the microscope. This organism has very fast movement and many legs. Another observation we made was that they swim upside down instead of right side up. Bothe of he fairy shrimps were translucent. The colors of them are determined by the food supply of their environment

environment. The reason why I did it was because I wanted to find out where in the environment bacteria and fungi can live. In order to do my study I had to collect a sample of soil and put it in a dish. After I did that I could look at it underneath a microscope. I found that bacteria did in fact live in the soil so the soil was a sustainable environment for the bacteria to live. Introduction: The problem that I investigated was where in the environment would certain bacteria and fungi be more common

How does the relationship between salt concentration effect osmosis in the aquatic plant Elodea? Quantitative data From observing the cells under a microscope‚ we see that they are continuously moving and therefore are alive. We have observed that when the cells are in the 10% sodium chloride‚ the chloroplasts are positioned to the sides of the cell wall and the cytoplasm is more expanded. Cells in the distilled water are slightly smaller than the cells in the sodium chloride solution and

Benedict reagent is probably positive for glucose because it is a fructose. Distilled water with Benedict reagent should be negative for glucose. The third experiment to test for starch using with and without the IKI reagent by looking under a microscope a slice of potato cells should have several shapes to it and with the IKI reagent should look have more of a stronger shapes and color to it. The onion cells should have a more stringy look to it and with the IKI more color. The fourth experiment

people developed the tools that could assist us to study those tiny organisms that cannot be seen by the naked eye. In the year 1590‚ the very early microscope was invented. (Satellite Events Enterprises Inc.‚ 1999) This tool made it easy to see microscopic organisms that people were unable to ever seen before. The first time that the microscope was used to in a study was in the early 1660’s by the English Scientist Robert Hooke. Hooke examined plants and that is when he first saw what we now
