INTRODUCTION As for the visual documentation of a living or dead specimen‚ digital photography has largely replaced traditional illustrations of the living specimen as the standard method of recording the colour and anatomy of the specimen in the field today. Earlier traditional illustration (coloured and black and white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations

1. Introduction Microscopy is an essential technique not only in cell biology but natural science as a whole. We compared different types of microscopic techniques ‚ according to the specimen used and the scope of the experiment. Two specimens‚ stained and unstained‚ containing CHO cells‚ were prepared‚ examined and analyzed under the microscope using bright field (HF)‚ dark field (DF) and phase contrast (PH) settings. In addition‚ the four phases of cell division cycle were estimated.. Bright

Introduction: The purpose of this lab was to differentiate chemical changes from physical changes. During the separation lab we were given a test tube with Styrofoam‚ sand‚ salt‚ and Iron fillings in it‚ our goal was to issolate each component from the other. We were given certain tools and materials to help us figure out how to divide the components‚ therefore creating our lab. Doing this lab helped us figure out what component used physical change and which used chemical change‚ it also showed
