Although I was only there for a short period of time I saw general x-rays, CT scans and ultrasounds. The images I saw in absence of being able to observe the exam included bariums (swallows and enema), MRI and I was also shown an interesting cases folder they keep for students. I feel the opportunity solidified my desire to work in radiography. It conveyed that it is a career that combines three elements which I am interested in; patient care, technology and science. I have a great interest in science- particularly biology which I
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.
And do the same procedure from step 3. Do the same procedure again from step 3 but this time putting the net more closer to the ground but not touching the ground. Now after you are done with steps from 3 to 5 pour the bucket water into the tray and examine the water to find different types of species of animals in the water. Use the spoon to scoop up the species and put it in the microscope to get a better view of the species and try to identify the specimen/species of
To be call life, it also must have biological nervous system. Geologists identify the evidence for life through different methods. Fossil Record is the one of the most common way the geologists use to identify the history of life today. They are “any preserved evidence of life from a past geological age.” However, fossilization is rare, only hard part can be preserved, but it usually decayed before it can be preserved. Molecular Record usually contains information of history that is based on the current organisms.
It is very easy and simple to conduct an experiment on C. elegans that’s why the majority of laboratories use this organism. The reason for using the C. elegans in an experiment and in research’s is because they are harmless it humans they are non-parasitic. C. elegans grows on. E. coli which can be easily found in rotten fruit or vegetables. This organism is very small and can be handled easily the adult C. elegans is about 1mm in length, C. elegans have
In nature, C. crescentus usually adopts a curved shape attributed to the presence of a cytoskeletal protein called crescentin (CreS). But when creS mutants which have a straight shape, were grown in laboratory conditions they did show any visible defect in growth rates. This raised the question: Does the commonly curved shape confer any selective advantage to the bacteria? The answer is apparently yes. In their natural environment which is freshwater lakes and streams, C. crescentus experience moderate flow.
Biology isn’t focused solely on humans and their existence. The concept of biology is a broad one as it focuses on more than one species of living thing. Biology also focuses on other living things such animals, bacteria, fungus and so much more. There are also several branches of biology. Some branches of biology are palaeontology which is the “study life in the past” (McMillian Science page 44); it is the study of fossil animals and plants.
Microscopes can be divided into several different classes. The most commonly used microscope is the light or optical microscope where light is used to generate the image. The second microscope is the electron microscope which unlike the optical microscope uses the electron beams instead of light. The last microscope is the scanning probe microscope where with the help of a probe the specimen gets scanned and the image gets formed. The microscope has helped humankind a lot in the medical field in several ways.
Bacterial culture is a perfect way to study the growth rate. This method is not specified for a matter, it is a necessary part of microbiological studies. The growth of bacterial cells is affected by different factors such as temperature, waste, pH and nutrients resources. Since the study is related to numbers and amount of substances, mathematical methods are needed to know the quantity of bacteria in the experiment hence, exponential. In addition, growth rate is proportional to the number of cells.
The microbiology laboratory is take a sample from patient to know what type of bacteria or another microorganism a causing the disease, and what the best treatment for it. The main purpose of the microbiology laboratory is work to discover the reason and causes of the diseases and treatment medical microbiology laboratory is one of important laboratory in clinical laboratory. The microbiology laboratory is very important that help to the diagnosis and pathogenesis of infectious diseases . The microbiology laboratory has many section such as bacteriology, parasitology, virology and mycology . Microbiology laboratory has many sections and each section do many type of test.
