The invention of the microscope help the development of the cell theory by allowing them to see the cell clearly and know the most amount of information about new discoveries. 2a. How do microscopes work?
Then, 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
Question 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. Modified Mercalli Intensity Scale: Measures the intensity of an earthquake Richter Scale: Used to measure the magnitude of an earthquake (Tarbuck, 2013)
Bacteria 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.
Obtain a small sample of the red epidermal cells from the stalk of the rhubarb by carefully peeling away the layer with forceps. Prepare a wet mount slide of the rhubarb tissue in distilled water only. View your slide under low power on your microscope, and then switch to high power. Draw a diagram of the field of view, and label.
Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. 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.
These 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
Unknown Lab Report Mikee Lianne Gonzales Biol 351- 1005 Holly Martin Unknown: # 76 Abstract This report is about identifying the respective genus of the given unknown organism. The goal is to show and prove the student’s understanding of microbiology and laboratory learned experimental techniques.
DNA Fingerprinting Using Agarose Gel S. Aaron Sowards Bio 122 Lab 04 Brianna Adanitsch Jakob Lester Minhenga Ngijoi 2/21/18 Dr. Chad R. Sethman Abstract DNA fingerprinting is the process of analyzing an individual’s DNA base-pair patterns. The DNA fingerprinting lab involved identifying the suspect using Agarose Gel and Polymerase Chain Reaction. It was found that suspect two s DNA matched the crime scene DNA.

The GOM system was utilised to photogram and create fringe projections of the deceased external findings. Photogrammetry is accomplished by taking photographs from varying angles; this will allow measuring distances in the created 3D model. Figure
Introduction 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.
Microbes were the first organism to occupy the Earth. They are a group of the smallest organisms and are single cellular organisms. Microbes are becoming important in areas such as biochemistry, genetics, agriculture and medicine. They are also important decomposers. One example, of a microbial life is the prokaryotes called bacteria.
Crime 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.
