Importance Of Microscope
The microscope is one of the most important tools used in chemistry and biology. This instrument allows you to magnify an object to look at it in detail. Many types of microscopes exist, allowing different levels of magnification and producing different types of images. It is also very important in microbiology fields, it enables them to study specimens that are too small to see with the naked eye. In microbiology, microscope is an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times. Light (natural or artificial) is transmitted through, or reflected from, the specimen and then passed through a system of lenses that produce a magnified image. It is also possible to measure the actual size of your specimen. A mini ruler called an eyepiece graticule that is placed in the eyepiece is needed. This is then calibrated using a special microscope slide called a stage micrometer. There are two types of microscope that are simple microscope and compound microscope. Simple microscope is a single lens system that magnifies the object being viewed. Compound microscope consists of two lenses. The image produced by the first of the two lenses is remagnified by the second lens. The magnification is thus compounded. The microscope we used in the experiment is light microscope, it is an example of compound microscope. The compound microscope is the most familiar form of optical microscope. A

839 Words | 4 PagesBacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt.

1830 Words | 8 PagesQuestion Set 7 A) What types of methods and tools are used to measure, document and analyze ancient fault activity along the San Andreas Fault and its associated faults? For example, how do geologists determine how long a fault has been active, how often it ruptures, its relative offset motion, and how much offset? Note that the term "ancient" means fault activity that occurred thousands to millions of years ago - long before seismologists were around.

1444 Words | 6 PagesThese microorganisms are used to teach us how multicellular organisms came to be and how they can survive today. These small, microscopic organisms are so unique that the identification of them is paramount in the advancements of science. Knowing the chemical makeup, the shape, and the biochemical processes is important in identifying these organisms to understand how they survive and where. A number of tests can be ran on an unknown bacteria to determine their ideal

692 Words | 3 PagesThen, by holding the nose of the bullet pointing away from you, the direction the impressions run away from you (either to your left or right) determines the direction of twist. If the rifling impression pattern on the bullet matches the rifling pattern in the barrel of the questioned firearm, the next step is to measure the rifling impressions on the bullet. The lands and grooves on a bullet are measured in thousandths of an inch or in millimeters. One way to measure individual rifling impressions is to use a micrometer, or with advanced technology the majority of crime labs use a comparison microscope; which is two microscopes connected to an optical bridge which allows the viewer to observe two objects simultaneously with the same degree of

1125 Words | 5 PagesDescribe the main difference between a compound light microscope and a dissecting scope. The main difference between a compound light microscope and a dissecting scope is that a light microscope has a higher resolution and a dissecting scope displays the image in a 3D form. 6. a. Distinguish between magnification and resolution? The difference between magnification and resolution is that magnification refers to how large an object appears compared to its actual size, while resolution describes how clear the specimen can be viewed in the microscope.

They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.

Chromatography Lab Report Discussion
1458 Words | 6 PagesIntroduction The term chromatography actually means colour writing, and signifies a technique by which the substance to be examined is placed in a vertical glass tube containing an adsorbent, the different segments of the substance traveling through the adsorbent at distinctive rates of velocity, according to their degree of attraction to it, and producing bands of colour at different levels of the adsorption column. The substances least absorbed emerge earliest; those more strongly absorbed emerge later. (Wixom et al., 2011) In chromatography of all types, there is a mobile phase and a stationary phase.
Why Is Crime Scene Photography Important
879 Words | 4 PagesCrime scene photography, sometimes referred to as forensic photography or forensic imaging, is the art of producing an accurate representation of an accident or crime scene. Crime scene photography is an important asset in the collection of evidence at the crime scene, documents the appearance and location of victims, shell casings, footprints, bloodstain patterns, and other physical evidence. In order for photographs to be admissible in a court of law, the standard for photographs of crime scenes and evidence must be of sufficient quality. Photography has a vital role in the decision made in court because the pictures are to represent the scene as it was exactly. Digital SLR single reflex camera is the most often used camera in crime scene investigations.
