the blood under a microscope and counted the blood cells. Another way to diagnose Acute Lymphoblastic Leukemia (ALL) is through a bone marrow biopsy, the child is sedated and given a shot in the hip area to numb it. After the hip on the child is numbed the area is ready for the biopsy. A thin needle is quickly inserted into a bone in the hip and a small amount of marrow is removed. The bone marrow from the hip is then sent to the laboratory where it is examined under the microscope to determine…

organism among other things with a microscope that had a magnification of up to 500X. Through the microscope lenses, he observed cells. He was able to become the first person ever to describe the single celled organisms after he looked at the matter scraped from his teeth. Van Leeuwenhoek published and wrote about his findings just like Robert Hooke and called the single celled organisms “animalcules”. During his time, Antony not only improved the design of the microscope through his more…

Viruses are miniscule organisms which are too small to be seen with a normal microscope. Invented in the 1940s, the electron microscope allowed scientists to see that a virus is nothing more than a core of genetic material (RNA or DNA), concealed in a protective protein coat. The tiny agents of disease are not referred to as living things, due to the fact that they cannot replicate on their own. They must attack the cells of another living organism and take over the cells' machinery to then make…

Dr. Edmond Locard is considered to be the father of forensics. He was a French criminalist who had created a principle called the Locard's exchange principle. Before he started working on his law career, he had began working as an assistant to Dr. Alexandre Lacassagne; he passed his bar exam in 1907. During World War I, Locard began to worked as a medical examiner with the French Secret Service. By examining the stains and damages on the soldiers and prisoners uniforms, he could determine the…

would be separated by doing a careful disection. Dr. Mark Adeelman donated the rhodamine-123 for the study which was used a methanol stock. This stock was used for the fluorescent probes. In order to be able to examine the lens with the confocal microscope one needs to stain it with the fluorescent dye. This process didn 't seem to work accordingly therefore another method was adapted lens slicing. Article two states that although cell on the outer layer of the slice was being damaged there were…

Introduction Evolution is the process in which organisms change from one generation to the next over a period of time. The Hardy-Weinberg equation is one of the most popular ways to determine if a certain trait within a population is changing. The Hardy-Weinberg equation provides a null-hypothesis to compare to the observation of the population. One can predict the outcome of the estimated amount of offspring in a population by using two alleles to determine which will be present in future…

timer, a microscope tray and a microscope. First, our group gathered our focal temperature water at 40°C and a Daphnia Magna as the equipment was set to collect its heart rate. We then placed the organism outside room temperature water into the 40°C water and allowed it acclimate for an interval of 30 seconds. When the time was met, we used the dropper to place the Daphnia Magna onto microscope tray with the net attached for support. Next, we examined the Daphnia Magna underneath the microscope…

States when he was two years old because his father was a Methodist minister. Baez grew up in Brooklyn and considered becoming a minister before turning to mathematics and physics. He made important contributions to the early development of X-ray microscopes and later X-ray telescopes.[1][2] Contents [hide] 1 Early life 2 Academic life 3 Retirement 4 References 5 Further reading Early life[edit] Baez's father was a Methodist minister who had left Catholicism when his son was two. During his…

Step 1. Make Drosophila culture medium First, to prepare a culture medium, four plastic vials were obtained and labeled with numbers 1 – 4. In each of the four vials, two teaspoons of medium mixture were added. Next, using a graduated cylinder, tap water (10 mL) was added to each vial containing the culture medium. Upon addition of water, white culture medium turned blue. Additional amounts of tap water were added to each vial to provide more moisture. Next, three grains of yeast were…

room’ a word used by Hooke (in the year 1665 while observing a cell with the microscope he built by himself) to describe the cells. The cell is considered as a living thing because it has the ability to metabolize, grow and reproduce. Before the invention of microscope, it was difficult to talk about cells as they were tiny and so not visible with the naked eyes but in the 17th century after the invention of the microscope, Robert Hooke and Anton van Leuwenhoek (1675) were able to see and draw…
