- PARTS OF THE MICROSCOPE. Match Column A with Columns B and C. Example: 1). A, C1. Identify features of Dark-field Microscopy (1-2 paragraph) 2. Give three examples of the uses of microscopes outside the field of biology and medicine. (3 examples with 5sentences explanation each)How does the microscopy in Figure 2 show that the capsule and an S-layer can exist in the same cell at the same time? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/
- Non-conducting materials can be studied by scanning tunneling microscope(STM). 1.True 2. FalseTell me three things that you know about microscopes? Why do we use them? How do you feel about using them in the lab?A student missed the laboratory period where the use of the microscope was demonstrated. The instructor asked the student to read the description in the laboratory manual and then proceed to examine bacterial cells with the oil immersion lens. The student skimmed the directions and began. After about 15 minutes of struggling, the student gave up in despair without seeing anything. Below is a detailed description of what the student did. How many mistakes did the student make and why didn’t the student see anything? a. Plugged in the microscope and turned the light source to maximum intensity. Made a wet mount and placed it on the stage with the low-power objective lens in position. Tried to focus with the coarse adjustment, but decided the bacteria were too small and needed to be seen with the high-power objective lens. Rotated the high-power objective lens into position, but saw the lens would likely touch the slide, so lowered the stage so that the objective lens rotated freely.…
- A lab revolving around compound microscopes was conducted. Please answer the following questions (questions 1, 2, and 3).

Which objective should be in position before you start to focus the microscope? Which focus knob should you use first with this objective?Which microscopy technique is BEST at determining the presence of physical microbial interaction(s)? a Light microscopy. b Scanning or transmission electron microscopy. c Fluorescent microscopy. d Phase contrast microscopy.1.
