Microscope components

Then, observations were made of the mCherry fluorescence under a fluorescent microscope with a “Flur 20X” objective and FIT-C Filter Set, which produced green light and made the specimen’s basal body formation glow red (shown in Fig. 6). Each strain of fixed cells was prepared on a separate wet mount slide, and the observations made…

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…

Since producers won’t be able to make food, the consumers won’t be able to eat, and then decomposers won’t have anything to decompose and break down. The cycling in the ecosystems will eventually not happen so the ecosystem will fall apart. Other trees that have already grown are blocking the sunlight from reaching the sprouts. In other words many sprouts are competing for the sparse amount of sunlight. The sprouts may also be competing for water and other ingredients necessary to grow.…

Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down…

Recruitment of Organisms in the Galveston Ship Channel Abstract A study was done in the Galveston Ship Channel to see the recruitment of sessile or fouling organisms to a substrate. A total of six organisms were found. They were Barnacles, Serpulid Worms, Bryozoan, Limpets, Tunicates, and Amphipods. Recruitment structures were created by the students and were put into the Galveston Ship Channel and left for five weeks to allow adequate time for organisms to adhere to it. A full mesh cage was…

1. Inquiry, inquiry based learning, is when simple observations turn into a curious question like “Why does it do that?” “Why does it change colors?” “What makes it move?”. Then that simple observation will catalyze an experiment, causing the individual to make a discovery proving that their idea is right or wrong. They will learn through trial and error, they will be able to grasp why something is the way it is or why that happens. 2. An example of a guided inquiry project I could facilitate…

important roles in the savanna and help biotic factors live. Fire as we know burns and destroys many things. Although this is true it actually helps renew and change the savanna so that it doesn’t become a tropical forest. The soil also is a big component because without soil there would not be plants and without plants the animals would not be able to survive. These 2 abiotic factors, although, they are small they definitely have a great impact on the…

(EDS) images and spectra were obtained from various samples of silica and platinum on silica. Each sample contains unique structures which were prepared by etching the surface of silica in different conditions. A scanning electron microscope is a type of electron microscope that produces images of topography and composition by scanning a sample with a focused beam of electrons. Samples can be observed in high vacuum, low vacuum, in wet conditions, or at elevated temperatures. The images in this…

Spatial variability in local plankton communities can have large effects on the composition and diversity of the secondary production with in an area. Therefore, it is important for scientists to study the factors that affect plankton community’s abundance, diversity and dominance. In this study multiple physical and biological factors were observed in order to examine how surface plankton communities varied with distance from shore in the nearshore environment of the Southern California Bight.…

This study examined the effects of physical factors on diversity in freshwater environments by observing invertebrate diversity in riffles and pools in a freshwater stream. It was hypothesized that differences in invertebrate diversity between riffles and pools would be due to physical factors in the environment. To test this hypothesis, invertebrates were collected from each environment and classified by their taxa, and Shannon-Simpson indices were produced from these data to analyze the…
