different species of protists found in pond water. The group prepared a preparation to be able to culture the protists until it was time to view them. After a few days‚ the group got a few drops of water from the preparation and observed it under the microscope. The experiment was a success because the group got to see the structure of the protists. They also saw the protists moving and feeding. The group saw some protists‚ mostly Paramecium caudatum and Balantidium coli. The group also saw a Paramecium

We let them sit for two nights in a row and while in class checked for different organisms under microscopes. We calculated the different amount of species and how many there were of each. Introduction: Antonio Berlese was an Italian entomologist. He worked on pest insects (arthropods)‚ usually those of fruit trees. Arthropods are the most successful

A Full Laboratory Report on: The Detailed Microstucture of Primary Materials This report presents a study on the microstructure of 8 material samples using the proper optical microscopy techniques. Emphasis is given in sample preparation‚ the right use of transmitting and reflecting optical microscopy methods‚ and a detailed analysis of the distinct microstructure of metal‚ ceramic‚ and polymer materials. For metals and ceramics‚ preparation procedures include grinding‚ polishing‚ and surface

This will be done using my powers of observation and testing numerous factors‚ Later the water will be observed under a microscope slide. Hypothesis The larger pond will hold a wider array of biotic factors but similar abiotic factors. Variables Independent: Choice of pond Dependent: Biotic and abiotic factors at the pond sites.

| 20.0 | 250.0 | 20.0 | 150.0 | 30.0 | Observations: The appearance of the Allium cepa cells through the microscope was more of a regular‚ rectangular shape in brown colour. The colour of the cell was due to the iodine solution used to stain. As the size of the Allium cepa cells was bigger‚ the nucleus and cell wall of the cells could also be spotted through the microscope. On the other hand‚ the cells of Ovibos moschatus Oculi were in an irregular shape with much smaller size. Thus‚ the

Overview Plankton is a microscopic drifting organism present in most of the water bodies around the world. There are three categories of plankton‚ but only Phytoplankton and Zooplankton are of our interest. Phytoplankton is the primary producer and forms the base of food chain in most water bodies. Among these phytoplankton groups‚ there are some species that harm aquatic organisms mechanically or by toxin production either at low concentrations or by forming high concentration blooms known as Harmful

MB2: THE MISSED CANAL A source of great frustration associated with the endodontic therapy of maxillary molars is whether or not a second mesiobuccal canal (MB2) exists‚ and to what extent practitioners should go in pursuit of locating it. Failure to find and to fill a canal influences the prognosis of endodontic treatment. The frequency of second canal in mesiobuccal root of maxillary molars is quite high‚ so time should be devoted in its location and treatment. The present article describes
