Micrometer

The five isolated nuclei measured had lengths of 2.5µm, 5µm, 3µm, 5µm, and 4µm, and therefore an average length of 3.9 micrometers. This data reflects an almost accurate measurement because according to Essential Cell Biology eukaryotic nuclei have an average length of about 5 micrometers (p.16). The total number of nuclei isolated was 3,125,000. This number was calculated by multiplying the amount of nuclei found per mL by five because 5mL was the size of the sample taken. The amount of nuclei per

could not be taken. The ruler was measured under 40x, 100x, and 400x magnification. First, the ruler was measured under 40x magnification and had a diameter across the field of view of about 4.5 millimeters. The fit number was converted to 4,500 micrometers. When the magnification increased to 100x magnification, the field of view decreased to 1.8 millimeters in diameter.

structures such as cell wall, nucleus and other unique features of microorganisms, learning different techniques such as proper handling and use of microscope, knowledge to prepare a smear from broth, gram staining, measuring microorganisms using ocular micrometer and to learn aseptic (sterile) techniques. The cell is the smallest basic structural, functional and biological unit of life. As we know variety of different types of cell, they all differ in their type on the basis of their structure and function

adhesive ability is given by various hair-type augmentations, called setae, on the feet of the gecko. Gecko setae incorporate stalks having widths in the scope of 5 micrometers. At the distal end, each one stalk limbs out into nano-sized spatulae, with approximately 100 to 1000 spatulae on each one stalk, each of which is around 0.2 micrometers long. Bond between the spatulae and a reaching surface is gotten because of vander Waals powers. The appealing constrains between a solitary spatula and a surface

appropriate, experimental procedures are planned, designed and evaluated properly, the use of microscopes, producing valid results and recording results. To develop techniques of measuring the size of plant fibers under microscope using stage micrometer and eyepiece graticule. Introduction: Pumpkin plant Pumpkin is of the genus Cucurbita and family Cucurbitaceae . Pumpkins are grown all around the world for a variety of reasons ranging from agricultural purposes

engineer’s workshop are Micrometers, Bore Gauges and Vernier Callipers (pictures found in Appendix A). They are a useful tool because they can give very accurate measurements for specific components and parts; as these will measure very small distances. Which could be the difference between a very smooth and effective engine opposed to a rough and uneconomical one. There are three main basic types of micrometer: inside, outside and depth (see Appendix A). An outside micrometer is used for measuring

numerous of the eukaryotic cell organelles (Plant, Animal and Bacterial Cells). Animal cells doesn’t contain a cell wall, plasmids, chloroplasts and permanent vacuole” (Plant, Animal and Bacterial Cells). The size of this cells “range from 10 to 30 micrometers in length (Bailey). The Animal cells tends to “come in various sizes and tend to have round or irregular shapes (Bailey). Lastly, the way that animal cell gets energy is by “the form of the complex carbohydrate glycogen” (Bailey). Plant cells are

Comparing the Zeeman Effect of Different Wavelengths of Light Group 32: Matthew Howard, Harriet King, Daniel Moore Abstract The experiment’s purpose was to observe the Zeeman effect on light through two different colour filters (a yellow filter and a green filter) to see if there a significant change in the fringe pattern between the two colours when the magnetic field is at different values. The Zeeman effect is when light from a gaseous light source travels through an external applied magnetic

Identification of Unknown Organisms Benjamin Nibarger Professor Hoffman Monday 11:15 AM Group Members - Jamie Jerome, Natalie Perez, Ruth Pinzon September 27, 2014   Introduction The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi

Pseudomonas aeruginosa, was a gram-negative aerobe, which was the first piece of evidence used to narrow down to the identification of the unknown. The morphology of the unknown was short rods organized in pairs, and they were about 1 micrometer wide and 3 micrometers long. It also showed true motility, which
