Cell Story It all started on October 18. I had Biology homework, and I forgot about it until about 11:30 pm. I was about a third of the way done filling out my diagram, and I think that I was just a bit too tired. I was having trouble spelling the word cell, which gives you a pretty good picture of my mental state. I messed up so many times that I had to get two extra erasers just to get as far as I did. But, as I read about lysosomes and mitochondria, I knew it was a losing battle. I was never…
An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…
Campana Lab Starting of Lab They have been given a vacuum sealed preserved Squalus Acanthias. They cut open the top of the bag and drained the fluid into the sink. Then they cut open the top of the bag and drained the fluid into the sink. Then they grabbed the tools they needed to dissect the Squalus Acanthias. Tools that were used are forceps, metzenbaum scissors, scalpels, and teaser needles (angled and straight). They put the Squalus Acanthias into a pan. They measured it and it was 31…
methylene blue on a slide, then smear a toothpick amongst the inside of the cheek, lastly smear the toothpick onto the stained slide. Cheek cells just like starch cells are hard to be viewed without the addition of a staining chemical, in this case, the methylene blue will make the cheek cells have a slight blue tint so they are more easily observed. Place the slide on the stage of the microscope then view and center the cheek cells under the scanning-power objective, move the slide and alter…
Created by Ernest Ruska and Max Knoll of the Berlin Technische Hochschule in 1931, the invention of this novel microscope allowed for the surpassing of the visible light resolution barrier. Since its inception, the TEM has become a resolution standard in the field of imagery, and further advances have led to the progression of high quality atomic viewing. The development of the electron microscope in the 1930s revolutionized biology, allowing for organelles, such as mitochondria, to be seen in…
Running late, I speed into the Matt Ross Community Center parking lot Saturday, September 10th while the clock on my dashboard turns to 2:15. I park my car, grab my bag, and begin to briskly walk into the building, my whistle bouncing against my chest with each step. The brick crosswalk underfoot, the flags blowing in the breeze, and cars driving on the busy streets of downtown Overland Park greet everyone who visits the center. Pushing my way through the glass doors, the employees at the front…
it be physical or emotional. But everyone does not have the courage or strength to push through troubled times, and many people fall short. In the stories “Up the Slide” by Jack London and “Glow in the Dark” by Gary Paulsen, the main characters go through an ordeal, and manage to persevere. While Clay, the main character of “Up the Slide”, faces a physical hardship, the narrator of “Glow in the Dark” faces an emotional ordeal. The themes of the texts are similar in a way, but the mood of the…
playing, while outside he was running around and said, “They are telling secretes about me and they are not telling”. After that he ran away to the playground with the swings, and slide. I walked behind him trying to understand what was going on, as he ran as soon as he told me that statement. While walking up the steps in the slide one of the supposed kids who was telling secretes was in front of him. The kinder gardener grabbed his leg and started to pull him down. I told to stop as I was…
I wasn’t happy with that suggestion since I really wanted to go on the blow up slide, but I had not wish to be rude, so I reluctantly replied with “ok.” As we went around the festival all I could think about the blow up slide, sure the other rides were fun, but I was convinced that the slide will be so much better. The closer and closer we got to the slide, the harder and harder it became to hold in my excitement, which caused me to start to bounce around. Matt just…
for people to do their. It is about six hours from mount Rushmore tho we were gonna go there while we were in north Dakota but we didn't but in Jamestown we found a pioneer village. I had a lot of fun while I was in Jamestown going down the water slides and going to pioneer…
