b. A group of spine animals.
c. Cells with a nucleus.
d. A group of one-celled organisms with no nucleus in their cells.

- 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.arrow_forwardGive typing answer with explanation and conclusion The antibiotic bacitracin binds to bactoprenol after it inserts a peptidoglycan monomer into a bacterial cell wall. Explain why this would lead to the death of the bacterium. 2. Penicillin antibiotics bind the bacterial enzyme transpeptidase. Explain why this would lead to the death of the bacterium. 3.
