Which of the following is an advantage of confocal microscopy over conventional fluorescence microscopy? The interaction of the laser beam with the cell surface allows the imaging of individual macromolecules O Only out-of-focus light enters the microscope lens, making the object appear illuminated against a dark background The use of electrons instead of light to image the specimen results in greatly increased resolving power O Optical sections in a single plane of focus can be visualized at different depths in the specimen The natural contrast of an unstained specimen is enhanced
In your everyday life, you have probably noticed thatcertain instruments are ideal for certain situations. Forexample, you would use a spoon rather than a fork to eatsoup because a spoon is shaped for scooping, while soupwould slip between the tines of a fork. The use of idealinstruments also applies in science. In what situation(s)would the use of a light microscope be ideal, and why?
If you made a plant cell drawing and that drawing measured 100 mm, what is the plant cell's magnification that measured 20 µm under the microscope? Answer: You were interested to see a human cell under the microscope, so you went to the lab to look for a dye to stain human cells you looked for a stain called. Answer:
A student has a compound microscope equipped with 10X ocular lenses and 4X, 10X, 40X and 100X objective lenses. The student has a slide with cells that are -100 microns (1 micron = 103 mm) in diameter, and wants to view a magnified image of a %3D cell so that the cell appears to be 10 mm in diameter. Which objective lens should the student use? O 10X O 40X O 100X O 4X Question 7 2 pts

What does parfocal mean? How does this affect the process of using a microscope? What could happen if your microscope is not parfocal?
Imagine you are using a microscope with 5x eye pieces (instead of 10x like ours). If you change from the 10x objective lens to the 40x objective lens, how does the total magnification change? Group of answer choices: -it is 5 times stronger with the 40x -it is 5 times weaker with the 40x -it is 4 times stronger with the 40x -it is 30 units weaker -it is 30 units stronger -it is 4 times weaker with the 40x
If someone is looking at a fly wing that is 3mm long with a microscope, which objective would allow them to see the entire fly wing? Group of answer choices 40x 10x 4x 100x
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.…
