you are using a microscope with an R value of 0.3 micrometer to view two cells that are 400nm apart will they appear as one object or two objects?
In this case, remember the R value represents the smallest resolvable distance between two objects under the microscope. If the true distance between two objects is lower than R, you will see both cells as one. If the true distance between two objects is higher than the R value, you will see both objects separate. In this context, 400 nm is a lower distance than 0.3 micrometer, so, you will observe both cells as one.

1.) you place a stage micrometer on a microscope and focus in it so the stage micrometer and ocular micrometer are alighned at zero. you observe that 20 divisions of the ocular micrometer aligns with 0.15 millimeters on the stage micrometer, when using the 40x objective with a numerical aperature of 0.80. the ocular lens (eyepiece lens) has a power of 10x. You then remove the stage micrometer and place a slide containing cells onto the microscope and find that...
Which type of microscope would you use to view the three dimensional arrangement of cells in a biofilm community? explain your reasoning.
Imagine that you are observing two human cells under a microscope. They are both from the same individual but do not look the same. You can conclude: 1.The two cells do not have the same genome 2.The two cells have the same genome but are experssing different genes 3.It is impossible to tell if the two cells have the same genome from what we know about the samples. 4.One of the cells is prokaryotic while the other is eukaryotic
The diameter of the field of view of a microscope at 40X total magnification is 4.5 mm Suppose you were viewing an object using a total magnification of 250X. a) What is the field of view? b) If your object takes up 1/4 of the field at 250X, what is the approximate size of your object?
In focusing a compound microscope, one should view the slide under: Lowest magnification first Highest magnification first It doesn't matter which magnification one first views the slide No answer text provided. Question #12: What makes meiosis different from mitosis? Meiosis produces diploid cells, while mitosis produces haploid cells Meiosis does not have a G1 phase while mitosis has a G1 phase Homologous chromosomes randomly line up in pairs during metaphase I in meiosis, whereas in mitosis during metaphase, each chromosome...
. You observe plant cells living in various conditions using high power on your microscope. Describe what you would expect to see when examining plant cells taken from a high salt environment compared to those from an isotonic environment. What kind of differences do you expect to see? Why (include osmosis in your explanation)?
RESOLUTION: This property of the compound microscope is the degree to which the detail in the specimen is retained in the magnified image. It is the ability of a microscope to distinguish two closely spaced objects as separate and distinct entities. Conventional light microscopes have a resolution of about 0.2 μm. RESOLVING POWER (d) is the closest spacing between two points at which the points can still be seen rly as separate entities. The smaller the resolving power, the smaller...
You have a dish of mammalian cells in culture that are all about to enter mitosis (it is a synchronously replicating culture of cells). You add to the dish a drug that is a potent inhibitor of RhoA activity. Two hours later you analyze your cells under the microscope. Which of the following best describes what you might observe ? A. All cells appear to be in telophase. B. All cells appear to be at metaphase. C....
you are using a microscope with an objective lens with a numerical aperture of 0.75 and light source with a wavelength of 500nm what is the R?
Emphasis Heading 1 Heading 2 b. With a compound microscope, which objective lens would you use to initially locate a specimen? (1 ) C. Mary is using the high-oil objective to view a strand of her hair. What is the total magnification at which she is viewing her strand of hair? (1 pt) d. Which part of a compound microscope is the flat platform on which microscope slides with mounted specimens are placed for viewing? (1 pt) e. Which part...
