THIS IS A MULTIPART QUESTION, PLEASE ANSWER ALL QUESTION
Using the image:
5. Identify whether the organism is a green alga, a diatom, a dinoflagellate, Eubacterium, or a Cyanobacterium. Explain the characteristic(s) that led you to that identification.
6. a. What type of microscopy (brightfield, darkfield, or phase contrast) was to obtain the image? Explain how you can tell.
b. Name a different type of microscopy would be also appropriate to use to visualize the organism in the image. How would the image change if you used that type of microscopy instead?
7. The image was taken using a microscope that has 10X, 40X, and 100X objectives. What is a possible magnification for the ocular lens on this microscope? Explain your response or show calculations.
