- 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.Bacterium A Bacterium B Bacterium C Bacterium D A Phylogenic Tree is a way to show the relationships between species, the way a family tree shows relationships between people. We use similarties and differences between organisms to determine their relationships by placing them within the tree. Instructions (1) Pick an unknown bacterium from the top of this sheet, and beginning at the top of the tree use the prompt at each junction to decide which branch to move down. (2) Once at the bottom, the bacterium has been identified within the C phylogeny. Yes (3) Repeat with the remaining bacteria to determine how they're related! CILIA?

- Find the large nucleus located near the cell. Make several outline drawings to illustrate the successive changes of 1. shape of the amoeba. Make drawings of the Amoeba you observe, and label its structures. C O O liko mer 0 AS 6 0 O Paramecium -- Paramecia are quite large, straw-colored, slipper-shaped and move rapidly, and they are thus very noticeable. If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again. Often, Paramecia tend to move to the edges of the coverslip, and even "escape" the coverslip at its edges. The trick to slowing the Paramecia is to mix a drop of methyl cellulose with a drop of the cell culture, as…Labe A.
