Concept explainers
(a)
To determine: The type of microscope which is used to study the change in form of white blood cells.
Concept introduction: Microscopy is the use of microscope to see an object that cannot be seen by the naked eye. Light microscopy uses the light to view the specimen but, in electron microscopy, a beam of electron is used to view the specimen. With the help of light microscope, it can be possible to view different cell types, bacteria, algae, and fungi. Scanning electron microscope is used for topographical and compositional study of a sample.
(b)
To determine: The type of microscope which is used to study the surface texture of a hair.

- (a) If you were to magnify a cell 10,000-fold (typical of the magnification achievedusing an electron microscope), how big would it appear? Assume you are viewing a“typical” eukaryotic cell with a cellular diameter of 50 μm.(b) If this cell were a muscle cell (myocyte), how many molecules of actin could ithold? Assume the cell is spherical and no other cellular components are present; actinmolecules are spherical, with a diameter of 3.6 nm. (c) If this were a liver cell (hepatocyte) of the same dimensions, how manymitochondria could it hold? Assume the cell is spherical; no other cellular components arepresent; and the mitochondria are spherical, with a diameter of 1.5 μmarrow_forwardIn your everyday life, you have probably noticed that certain instruments are ideal for certain situations. For example, you would use a spoon rather than a fork to eat soup because a spoon is shaped for scooping, while soup would slip between the tines of a fork. The use of ideal instruments also applies in science. In what situation(s) would the use of a light microscope be ideal, and why?arrow_forwardDo you expect any color or labeling in onion cells? Why not? 2. Would you expect Lugol's Solution to stain onion cells? Why or why not? Finally, look at cheek cells. Can you find the nucleus? 3. What strikes you as different in terms of cell shape compared to onion cells or cork cells? Why do you think that is? Think about differences between animal and plant cells (Figure 4.4 and text on page 59 of your textbook).arrow_forward

"Eye color" refers to the color of the iris of the eye. Melanin is a dark pigment produced by cells in the iris that gives the eye its color. What determines the color of the eye is a combination of the amount, location, and qualities (e.g., different types) of the melanin present in the iris (Sturm & Larsson, 2009). The iris has a front layer and a back layer. The space in between them, called the stroma, is filled with various proteins, including white collagen fibers. For almost all eye colors, there is a lot of melanin on the back layer of the iris (Sturm & Larsson, 2009). Where people differ is in the melanin in the front layer of the iris. A lot of melanin in the front of the iris makes the eye look brown because, as light hits the front of the iris, the pigments absorb the light. Blue irises have less melanin in the front layer, so light can go through it. As light…arrow_forward
- -Mature parent cell Budding- cell 1 μη Test II. Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1 um. The scale bar works in the same way as a scale on a map, where, for example, 1 inch equals 1 mile. In this case the bar represents one thousandth of a millimeter. Using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. Start by measuring the scale bar and the diameter of each cell. The units you use are irrelevant, but working in millimeters is convenient. Divide each diameter by the length of the scale bar and then multiply by the scale bar's length value to give you the diameter in micrometers.arrow_forwardus DOD Part II-Eye Coloration Puzzled, Alexia and Evan used the internet to research the its color. what gives eye eye. the cyc "Eye color refers to the color of the iris of the Melanin is a dark pigment produced by cells in the iris that gives its color.
