This is a group assignment and I only need to do the introduction. Please see the attached doc where I have provided all information and answers regarding the experiment. Introduce the topic by describing the question, concern, variable that was tested. An introduction clearly defines the purpose of conducting the experiment and states the hypothesis.Include any background research conducted. Describe the types of microscopes and define the properties of microscope lenses such as magnification, resolution, inversion, and depth of field. Include how the size of a specimen can be determined using a microscope. Use in-text citations in APA format when referencing previous study background information retrieved from outside source.
