Using the microscope Answer the following questions as you work through this exercise: 1. How is the letter “e” on the slide oriented when you see it with the naked eye as you mount it on the stage (i.e., is it right side up or upside down)? 2. How is the letter “e” on the slide oriented when you see it under low or high power magnification? 3. What effect, if any, does the compound light microscope have on the orientation of the image?

Hi I hope you're doing fine. I need help with these questions, please!   thank you!

I don't understand this problem. Can you help me to explain to me? I'm lost and i have a hard time.

Using the provided materials and the microscope itself, review the parts of the microscope including the name, where it is located, its function and the appropriate times to use. Record your observations and notes as vou will require this information when writing yourlab report

Question 3 When carrying a microscope, what two part or parts should you be holding? Base O Coarse Adjustment Knob O Ocular Lens O Arm O Objective lens Stage

Please answer fast

Can you help me please

Question Completion Status: A Moving to another question will save this response. Question 13 Total Magnification of a microscope is O 1. Product of Ocular Lens and objective lens magnification O 2. Sum of the ocular lens and objective lens magnification O 3 Magnification of ocular lens minus magnification of objective lens O 4. None of above Moving to another question will save this response.

Hi, there! Just subscribed to Bartleby! So excited to be here, and thanks for your help! Can you assist me in answering this? (This is not graded but, rather, an excersise conducive to acquisition).

I have a hard time with this picture and I don't know which I put the right label on this picture. Can you help me?

Label the microscope

List the learning goals that was listed from the picture

USING & FOCUSING THE MICROSCOPE: 1. List the following items into their correct order for proper set-up & use of the microscope: set scanning lens (4x), set low power lens (10x), turn on power, place slide on stage, set light to medium, look through eyepiece (= oculars), fine adjustment focus, coarse adjustment focus, center specimen 1. 2. 3. 4. 5. 6. 7. 8. 9.

PART C: CALCULATING THE DIAMETER OF THE FIELD OF VIEW (FOV)_ The field of view (FOV) is the circular area you can see when you look through the microscope. The diameter of the field of view is different depending on which objective lens you are using. For example, you are using the medium-power objective lens, then the area you can see is actually smaller than if you were using the low-power objective lens. Knowing The diameter of the field of view can help you estimate actual size of objects / cells seen through the microscope. When the revolving nose piece is turned to the low power objective lens, a dear plastic ruler can be placed on the microscope stage (see figure 1). Then, the coarse adjustment knob can be used to focus on the millimeter marks of the ruler making sure that one of the milimeter marks is at the left edge of the field of view (see figure 2). NOTE: Slage cip I-1000 Objects in the FOV are usually measured in micrometers (um). To convert, a FOV in mm, times it by 1000…

What's New Great job! You made it! In the previous activity, you were able to familiarize a parts as well as to describe the functions of the microscope which is an important the in learning science. Furthermore, it is necessary for you to recognize the rolao microscopes in studying tiny objects and organisms and enable you to understand of itself. As a budding scientist, you should be able to develop the skill in manipulating the microscope, calculating how much objects are magnified under the microscope, and proper use and care of the microscope. Moreover, this is an expensive instrument. It neede to be handled carefully and properly. There are ways on how to useit. Tosee the image properly it should be used appropriately.

Please answer question 1

Shown below are several micrographs (images from microscopes) that were taken using different microscopy techniques. Write down what method of microscopy was used and why you thought so. Choices for microscopy techniques are: Transmitted Light Microscopy (techniques of brightfield, phase-contrast, darkfield, DIC all fall under this), Fluorescence Microscopy, Scanning Electron Microscopy, and Transmission Electron Microscopy.

I need help with a microbiology question comparison of the 3 types of microscopy including which shows more detail, which is clearer, and explain which would be preferred when observing paramecium. The three types of microscopy that were used to view paramecium were brightfield,darkfield, and phase-contrast microscopes. Thank you!

What 3 simple ways of preparing microscope slides for light microscopy.

When carrying a microscope you should always have one hand on the base and the other on the arm. True False

3. Please number these steps, in the order they should be completed when using a microscope. Remove specimen, lower stage, wrap cord, and return covered microscope to numbered shelf. Move to other objective lenses to increase magnification. Rotate lowest-magnification objective lens into position (probably 4x or 10x). Clean all lenses with lens paper. Place specimen on stage. Adjust chair to a comfortable height. Use coarse focus knob to adjust stage until an image is visible. Be careful to use only the fine focus knob with the longest objective lenses.

Answer the following questions and uploa assignment. 1. What is the difference between a zoom knob and focus knob? 2. What is another name for the ocular lens? 3. Define working distance. 4. When would you use top illumination vs. bottom illumination? 5. What two parts of the microscope should you touch when carrying it? MacBook Air 吕0 F3 F4 F5 F6 F7

Analysis: Write your answers on the space provided. 1. How does the letter “e” as seen through the microscope differ from the way an “e” normally appears? 2. When you move the slide to the left, in what direction does the letter “e” appear to move? When you move it to the right? Up? Down? 3. How does the ink appear under the microscope compared to normal view? 4. Why does a specimen placed under the microscope have to be thin?
