The active region displayed in Figure 1 show a larger pore and several smaller pores in G-band. Bright points and several micropores are also visible. This active region was observed from 18:08 UT to 23:38 UT. However, there are three gapes from 18:42 to 19:08 20:21 to 20:47 and 21:59 to 22:26. Figure 1 shows the first image of the time series. Figure 2 illustrates the evolution of the fine structures at the inner part of the granules (i.e. towards umbra) at the pore boundary. Several dark…

〖Na〗^+and K^+channel relationship Figure one shows the temporal relationship between 〖Na〗^+ conductance (g_Na) and K^+ conductance (g_(K )), and the relative changes in the V_m during an action potential. 〖 g〗_Na increased as the V_m moved towards 0 mV causing depolarization of the membrane and started to decrease immediately after the peak of the action potential. Whereas, g_(K ) increased immediately following the action potential peak during the repolarization of the plasma membrane where…

just as curious as George himself. Since the age of five, I’ve been amazed by chemistry (and I didn’t even know what it was). This included everything from why oil and water never mixed together to where my water disappeared to after being unattended. While the interactions of polar and nonpolar molecules drew my attention, I wanted to learn more about how molecules interact with each other, so I joined the AP Chemistry class offered at my high school. On the first day, I was overwhelmed. I…

Since the naming of the dinosaurs in 1842 it has been thought that their metabolisms were similar to current day ectothermic, cold blooded reptiles., In the 1960’s- 1970’s; however, it started to become apparent that an endothermic metabolism (warm blooded, like mammals) is more conformable with new evidence and observations. Originally, predictions on the paleothermometry of dinosaurs was based on the physical performance such as the estimation of running speed from trace fossils as well as…

For our experiment, we will test SRT protein ligaments in a variety of conditions to determine the functionality and resilience of SRT protein ligaments relative to artificial and native human ligaments tested under the same conditions. The first test will examine the effects of the internal environment of the human body on SRT proteins. For this section of the experiment, we will place SRT ligaments in a solution analogous, in temperature and acidity, to the environment of the human body. The…

Draw resonance structures showing all the positions at which the positive charge is delocalized on the aromatic ring in the phenonium ion. If a methoxy group (-OCH3) or a nitro group (–NO2) were substituted in the 4-position on the aromatic ring, how would the stability of the phenonium ion change? Compare methoxy substituted, nitro substituted and unsubstituted, and order them by increasing stability. Explain your answer thoroughly. 2) Benzopinacol and benzopinacolone have nearly…

atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of chemistry but also initiated its progression into a modern science. In 1869 Dmitri Mendeleev discovered that the properties of elements "were periodic functions of the their atomic weights.” This later on became known as the “Periodic Law.” At his…

Imagine trying to figure out one possible combination to a mixture, when there are over 100 possibilities. The 8th graders had to look at the physical and chemical properties, to somehow figure out the mixture. A group of students thinks that Baking Soda and Citric Acid is what’s in the mystery mixture. That group thinks that Baking Soda and Citric Acid is in it for a lot of reasons. One reason is that the mystery mixture has circular round objects in it and the Citric Acid is circular and…

1. What are your education goals? Graduation with a Chemistry Bachelor is my long-term goal. For me, on the studying journey, earning good grade is not everything. School is a place where I meet friends and professors; alternatively, access a variety of resources from them. 2. What do you envision yourself doing in a STEM career 10 years from now? In the future, I may work in the lab to create new medicine and vaccine that help others get over mental and physical pain. I might cooperate with…

To begin the experiment, the Spec 20 was turned on to warm up for 15 minutes and set to maximum absorbance wavelength. Ten test tubes were then prepared. The Spec 20 was set to 0% and a test tube of blank solution (water) was wiped off and placed into the Spec 20. Transmittance was then set to 100% to calibrate the machine. Next, five test tubes were prepared and labeled with one of the standard solutions of 0.05 M, 0.1 M, 0.2 M, and 0.5 M CuSO4 in them. The Spec 20 was set to 600 nm and %…
